Best Ls Valve Cover Gaskets for LS Engines

#1 · Best Overall

1. Michigan Motorsports LS Gasket Set

• Material: Rubber
• Warranty Description: 30 Days
• Material Type: Rubber

Best for: Grommets Included For Refreshes.

Why it ranks #1: Lists fitment for LS engines from 4.8L through 7.0L and includes both molded-rubber gaskets with pre-installed grommets.

Pre-installed grommets distinguish this Michigan Motorsports kit, which pairs them with both valve-cover gaskets for a more complete LS refresh. Its listed engine range runs from 4.8L to 7.0L, making it the broadest explicitly stated displacement coverage among these LS-focused gasket sets.

The kit combines both molded-rubber gaskets with pre-installed grommets, so the listed components address the sealing surfaces and grommet locations together during a valve-cover refresh. Michigan Motorsports specifies 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, and 7.0L LS engines. Its OEM-style direct-fit design is described as requiring no trimming or modification, while the rubber is intended to resist heat, oil, and pressure in service.

Skip it if you have a 7.0L LS engine and want only a gasket pair; the BTR pair lists fitment through 6.2L.

This kit fits buyers refreshing both covers on a listed LS engine who want grommets included and an OEM-style installation. Its range reaches 7.0L, but verify the specific engine and vehicle application before beginning the repair.

#2 · Best BTR Pair

2. BTR LS Gasket Pair

• Warranty Description: 30 Days

Best for: Complete Pair For Both Covers.

Why it ranks #2: A complete pair for 4.8L to 6.2L LS engines, with OEM-style dimensions and rubber described as heat- and oil-resistant.

Two gaskets for both valve covers make this BTR pair a practical choice when refreshing both sides of an LS engine at once. Its OEM-style molded-rubber construction is specified for 4.8L through 6.2L engines, connecting factory-style dimensions with a consistent-seal goal.

The pair is listed for 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L LS engines, and the description names LS1, LS3, LQ4, LM7, L96, and LC9 examples. Molded rubber and factory-spec dimensions are intended to provide proper compression, while resistance to heat and oil exposure addresses the conditions a valve-cover seal encounters. Supplying both sides supports a coordinated two-cover replacement rather than a one-sided repair.

Skip it if you want pre-installed grommets in the kit; the Michigan Motorsports AB631 set includes them.

This pair suits an LS owner replacing both valve-cover gaskets and seeking OEM-style dimensions in molded rubber. Its stated range covers engines through 6.2L; buyers needing grommets should note that the supplied listing does not include them in its stated contents.

#3 · Broad LS Fitment

3. Armker LS Gasket Set

• Material: Rubber
• Material Type: Rubber

Best for: Broad LS V8 Engine Coverage.

Why it ranks #3: Explicitly lists LS V8 capacities from 4.8L to 6.2L and describes a gasket set intended to restore the cover-to-head seal.

A stated 4.8L-to-6.2L LS V8 range is the Armker set’s key advantage, spanning several common engine sizes in one listing. Its rubber gaskets are presented as a replacement for worn seals, giving owners addressing oil seepage a direct valve-cover-to-cylinder-head sealing repair.

Armker lists compatibility with 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L LS V8 engines, making engine displacement the central fitment check. The product description connects hardened, heat-aged gaskets with oil leakage and says the replacement restores a seal between the valve cover and cylinder head. That makes it relevant for a seepage repair, while the supplied details do not specify included grommets or additional installation hardware.

Skip it if you need grommets explicitly included; the Michigan Motorsports AB631 set lists pre-installed grommets.

Choose this set when the engine falls within its listed LS displacement range and the job is focused on replacing worn valve-cover seals. Check the exact engine application, and account separately for grommets because their inclusion is not stated.

#4

4. Yeqeyiq LS Gasket Set

Best for: Gen III And IV Compatibility.

Why it ranks #4: Lists 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L LS engines, plus replacement references VS50504R1 and VS50250A.

Yeqeyiq names LS Gen III and Gen IV engines across 4.8L to 6.2L, giving this set a clearly stated span for owners identifying parts by engine family. The listing also names LS1, LS2, LS3, and LS6, tying its compatibility claims to familiar LS applications.

The listed range covers 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L V8 engines, with Gen III and Gen IV and several LS engine names specified. The set is described as rebuilding the seal between the valve cover and cylinder head to address seepage from aged, hardened gaskets. Its stated 1999–2020 Chevrolet, GMC, Cadillac, and Buick compatibility offers a vehicle-level reference, though engine-specific fit still matters.

Skip it if you need rubber construction and included grommets stated; the Michigan Motorsports AB631 listing specifies both.

Consider this set when your LS Gen III or Gen IV engine falls within the listed displacement range and the repair targets valve-cover seepage. The supplied details do not state material or grommet contents, so those requirements may call for another listing.

#5

5. ChaoTianxia Valve Cover Set

• Material: Rubber
• Material Type: Rubber

Best for: GM Vortec Vehicle Applications.

Why it ranks #5: Names 4.8L through 6.2L GM Vortec engines and replacement references VS50504R1, 12637683, and VS50250A.

A long GM vehicle list is the ChaoTianxia set’s practical differentiator, spanning Chevrolet, GMC, Cadillac, and Buick applications with 4.8L-to-6.2L Vortec fitment. For owners identifying the repair by vehicle name as well as engine size, that breadth makes the listing easier to screen.

ChaoTianxia specifies compatibility with 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L GM Vortec engines, then names vehicles including Silverado, Tahoe, Sierra, Yukon, Escalade, and Rainier. The molded-rubber gasket is described as providing a superior seal and resisting oil and high temperatures, relevant to the heat and fluid exposure around the covers. Several replacement references are supplied to help cross-check an existing part listing.

Skip it if you require grommets explicitly included; the Michigan Motorsports AB631 kit lists pre-installed grommets.

This option suits GM Vortec owners whose engine size and vehicle appear in its extensive application list. Its molded rubber is specified for oil and heat resistance, but buyers planning a full refresh should account for grommets separately unless confirmed.

#6

6. MNJWS Valve Cover Set

Best for: Vehicle-Listed GM Replacement.

Why it ranks #6: Lists 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L GM Vortec engines, though LS-specific construction details are limited.

Named Chevrolet, GMC, and Cadillac applications give the MNJWS gasket set a vehicle-focused fitment reference for common GM Vortec repairs. Its listed engine sizes run from 4.8L through 6.2L, while the stated purpose is to restore the seal between the valve cover and cylinder head.

The fitment information includes 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L GM Vortec engines and names vehicles such as Silverado, Suburban, Tahoe, Sierra, Yukon, and Escalade. The gasket is described as sealing the cover to the cylinder head to stop oil from escaping onto the engine. That makes it relevant when addressing leakage symptoms, though the supplied product details do not specify material or grommet contents.

Skip it if you want a stated molded-rubber gasket and included grommets; the Michigan Motorsports AB631 listing specifies both.

This set is suited to owners matching a listed GM vehicle and Vortec displacement who need a valve-cover leak repair. Material and grommet contents are not stated in the supplied details, so consider those points when planning the job.

#7

7. Fel-Pro VS 50504 R-1

• Material: Rubber
• Warranty Description: 30 Days
• Material Type: Rubber

Best for: Fel-Pro Repair-Surface Sealing.

Why it ranks #7: Fel-Pro describes application-specific sealing materials, but the supplied fitment details emphasize vehicle applications rather than an LS engine range.

Fel-Pro’s application-specific sealing materials are the defining feature of the VS 50504 R-1 set, helping address oil seepage at the valve-cover joint. Its listed vehicle applications include several GM models, including Cadillac Escalade variants, so it may suit a repair where those fitments match the vehicle and engine.

The rubber gasket set is intended to seal the valve cover to the cylinder head, which gives the repair a direct role in preventing oil from escaping at that joint. Fel-Pro also describes its gaskets as using application-specific materials and sealing innovations to help achieve a dependable seal. The supplied compatibility list names Buick, Cadillac, and Isuzu applications, but is incomplete; use the vehicle’s year, make, model, engine, and trim to verify fit before starting the repair.

Skip it if you need a clearly stated 4.8L–6.2L LS fitment range; the Armker set lists those engine sizes.

This is a candidate for a Fel-Pro repair on a vehicle within its listed applications, especially where application-specific sealing materials matter. The supplied fitment details are partial, so establish exact engine and vehicle compatibility before purchase.

#8

8. Fel-Pro VS 50504 R

• Material: Rubber
• Warranty Description: Contact retailer/seller for assistance
• Material Type: Rubber

Best for: Imperfect-Surface Fel-Pro Repair.

Why it ranks #8: The product lists a cork-rubber formulation and repair-oriented sealing, but the supplied fitment details do not clearly specify an LS engine range.

Fel-Pro specifically says the VS 50504 R is engineered for imperfect sealing surfaces, a useful distinction when a repair involves less-than-ideal mating surfaces. Its application-specific materials and listed GM vehicle fitments make it a candidate for a targeted replacement when the exact vehicle application matches.

The gasket set is intended to seal the valve cover to the cylinder head and prevent oil from escaping at the joint. Fel-Pro’s description says its proprietary cork-rubber formulation and repair-environment engineering help seal imperfect surfaces, which is relevant when restoring a used engine assembly. The supplied fitment list includes Buick, Cadillac, and Isuzu models but is partial; check the vehicle, engine, and trim before relying on it for an LS repair.

Skip it if you need explicit 4.8L–6.2L LS coverage; the Armker set lists those engine sizes.

Choose this Fel-Pro set when its vehicle application matches and sealing an imperfect surface is a priority in the repair. The fitment information supplied is incomplete and does not give an LS displacement range, so verify the exact engine application.

#9 · Single-Gasket Option

9. BTR LS Valve Cover Gasket

Best for: Single Replacement BTR Gasket.

Why it ranks #9: This BTR gasket is identified as LS-compatible and usable in place of GM part 12637683, but it is sold individually.

Sold individually is the crucial detail for this BTR LS valve-cover gasket: it suits a one-side replacement or a buyer assembling the required quantity separately. BTR identifies it as an OEM-quality gasket and says it can replace GM part 12637683.

The listing identifies a single LS valve-cover gasket, rather than a pair, so the quantity suits repairs requiring one gasket or buyers sourcing each side separately. BTR describes the part as OEM quality and states it can be used in place of GM part 12637683. Those details provide a specific cross-reference for part-based shopping, but the supplied information does not state an engine displacement range or material specification.

Skip it if you need both sides in one purchase; the BTR BTR-37683-2 listing supplies a pair for 4.8L–6.2L engines.

Pick this gasket when you need one BTR LS replacement and the GM 12637683 reference matches your part requirement. It is sold individually, so plan quantity for both covers and verify application details not supplied in the listing.

#10

10. Fel-Pro 1628 Gasket Set

• Material: Silicone
• Warranty Description: 30 Days
• Material Type: Silicone

Best for: Silicone And Steel-Core Construction.

Why it ranks #10: Its listed applications include several older GMP Performance V8 engines, not an LS-specific engine range, making it the least targeted option here.

A solid steel core inside molded silicone rubber sets the Fel-Pro 1628 apart, pairing reinforcement with a sealing material intended for valve-cover service. Its listed applications include several GMP Performance V8 displacements, making it a specialized option rather than a broadly stated LS-specific set.

Fel-Pro’s PermaDry molded-rubber formulation is described alongside a solid steel core, which adds strength to the gasket while the material is intended to maintain a seal. The application list names GMP Performance V8 engines from 4.3L through 6.6L, including 5.7L, plus 18 Degree High Port. Because this is a different stated application range from common LS fitment listings, buyers should use its specified engine applications to guide selection.

Skip it if you need named LS1–LS6 coverage; the Yeqeyiq set lists those engine families and 4.8L–6.2L fitment.

This Fel-Pro set is for buyers whose application matches its GMP Performance V8 or 18 Degree High Port listing and who value a steel-core construction. Its supplied fitment does not name common LS families, so select by exact engine application.
