Best Sbc Valve Springs For 600 Lift: Compare Seven Options

#1 · Best Overall

1. COMP Cams 26987-1

Best for: Single-spring orders for .600 lift.

Why it ranks #1: Its title explicitly lists .600 lift, 1.800-inch installed height, 1.442-inch outside diameter, a damper, and 391 lb/in.

The title explicitly identifies .600-inch lift, giving the Comp Cams 26987-1 a direct lift reference for buyers targeting that specification. It is a dual valve spring with damper, listed at 1.442 inches outside diameter and 1.800 inches installed height. The listing also names a 391-pound-per-inch rate and describes the item as single.

The .600-inch lift designation makes this spring directly relevant to a buyer screening for that target, while the 1.442-inch outside diameter and 1.800-inch installed height provide dimensions for a fit check. Its damper-equipped dual construction and listed 391-pound-per-inch rate add configuration and rate information for evaluating the spring with the rest of the valvetrain. The description calls the item single, so this listing is not a stated set of 16; plan the order quantity accordingly.

Skip it if you need a complete 16-spring set in one listing; this item is described as single, while COMP Cams 917-16 is listed as a set of 16.

This Comp Cams spring fits buyers screening for a .600-inch lift part who want a damper-equipped dual spring and can source the required quantity. Check its listed dimensions against the engine, and account for the single-item description.

#2 · Most Lift Capacity

2. COMP Cams 917-16

• Weight: 4.84 lb
• Dimensions: 13.5 x 3.7 x 2.9 in

Best for: Higher-lift builds near .600 inch.

Why it ranks #2: The dual spring lists .690-inch maximum lift, above the target, plus 200-pound seat load at 1.800 inches and 596-pound open load.

A .690-inch maximum-lift figure sets the COMP Cams 917-16 apart for builders evaluating lift headroom around a 600-lift target. This set of 16 dual springs also lists a 1.550-inch outside diameter and 0.824-inch inside diameter. Its 200-pound seat load and 596-pound open load are specified at stated heights.

The .690-inch maximum lift exceeds the 600-lift target named in the roundup, giving buyers a stated lift ceiling to compare against their cam specification. The 1.550-inch outside diameter and 0.824-inch inside diameter help screen the spring’s space requirements. Pressure figures are also provided: 200 pounds at a 1.800-inch seat height and 596 pounds at a 1.100-inch open height. Together, these details support a more informed check of lift, dimensions, and spring load before installation.

Skip it if you cannot accommodate a 1.550-inch outside diameter; compare the space available before choosing this spring.

The 917-16 suits builders seeking a stated lift ceiling above .600 inch and who can accommodate its 1.550-inch outside diameter. Use the listed load heights and dimensions to evaluate the complete valvetrain combination before installation.

#3 · Explicit 600-Lift Kit

3. Kibblewhite 20-20450

• Weight: 1.9 lb

Best for: 600-lift kit with alloy-steel springs.

Why it ranks #3: Its product title explicitly identifies a .600-inch-lift racing valve spring kit, although the listing provides no installed height or pressure figures.

The Kibblewhite 20-20450 is explicitly identified as a .600-inch-lift racing valve spring kit, making its lift designation the key differentiator for buyers targeting that figure. Its alloy-steel springs keep the supplied material clear, while the 1.9-pound kit weight offers a concrete handling detail. No spring pressures or installed height are provided.

The explicit .600-inch lift designation lets a buyer screen this kit against a cam’s stated lift without inferring capacity from dimensions that are not listed. Alloy steel identifies the spring material, and the included components are listed as springs, keeping the kit description specific. The 1.9-pound weight also gives a practical reference when handling the kit. Since the supplied information omits pressure figures and installed height, it cannot answer every valvetrain compatibility question on its own.

Skip it if you need stated seat pressure or installed height to complete your spring selection; neither figure is supplied for this kit.

The Kibblewhite 20-20450 is a candidate for a racing build targeting .600-inch lift, especially when alloy-steel springs suit the plan. Buyers who need pressure or installed-height data should obtain those figures before deciding whether it fits.

#4 · Race Street Option

4. COMP Cams 26925-16

• Weight: 3.23 lb
• Dimensions: 10.2 x 2.9 x 2.5 in

Best for: Street-strip hydraulic cam builds.

Why it ranks #4: The Race Street dual springs are described for race-oriented hydraulic flat and roller camshafts, with installed heights spanning 1.640 to 2.000 inches.

The COMP Cams 26925-16 Race Street line specifically accommodates race-oriented hydraulic flat and roller camshafts, making that application range its defining feature. This set has 16 dual springs, a 1.320-inch outside diameter, and a 1.810-inch installed height. The listing frames Race Street springs for street-and-track use, but gives no maximum lift figure.

COMP Cams identifies this Race Street spring line for race-oriented hydraulic flat and roller camshafts, giving builders a stated application context that spans street and track use. The 1.320-inch outside diameter and 1.810-inch installed height offer concrete dimensions for initial fit screening. Its 16-spring set supports a full-engine selection workflow, while the dual design and cited quality-control testing address strength, durability, and valve-train stability. No lift rating is supplied, so confirm capacity separately for a 600-lift cam.

Skip it if you require a listed .600-inch lift limit; the 26925-16 provides application and dimensions but no maximum lift figure.

The 26925-16 suits street-and-track builders using hydraulic flat or roller camshafts who want a 16-spring set. Its dimensions help with initial screening, but the listing does not confirm .600-inch lift capacity, so verify that boundary.

#5

5. COMP Cams 914-16

• Weight: 3.88 lb
• Dimensions: 13.5 x 3.7 x 2.9 in

Best for: Buyers checking pressure at 1.900 inches.

Why it ranks #5: This dual spring provides a 1.489-inch outside diameter and listed pressures of 122 pounds at 1.900 inches and 309 pounds at 1.400 inches.

A listed 122-pound seat pressure at 1.900 inches gives the COMP Cams 914-16 a specific pressure reference for spring selection. This set uses dual springs without a damper, with a 1.489-inch outside diameter and 0.819-inch inside diameter. Those figures help buyers screen dimensions and pressure, but the listing gives no maximum lift rating.

The 1.489-inch outside diameter and 0.819-inch inside diameter help a builder compare the spring’s envelope with available head and retainer space. Its 122-pound seat pressure at 1.900 inches and 309-pound open pressure at 1.400 inches provide useful reference points when checking a cam and valvetrain plan. The dual, damper-free design is explicitly identified, so buyers can account for that configuration during component selection; the supplied figures do not specify a 600-lift limit.

Skip it if you require a stated lift limit for a 600-lift build; the 914-16 lists pressures but no maximum lift figure.

Choose the 914-16 if its 1.489-inch outside diameter, 0.819-inch inside diameter, and pressure figures suit your build’s requirements. For a 600-lift application, establish lift capacity from information beyond the supplied listing before assembly.

#6

6. COMP Cams 995-16

• Weight: 3.9 lb

Best for: Damper-equipped dual spring selection.

Why it ranks #6: Its dual spring with damper has a 1.437-inch outside diameter and stated seat and open pressures, but the listing does not state a lift limit.

A listed 336-pound open pressure at 1.150 inches gives the COMP Cams 995-16 a concrete pressure point for buyers comparing spring requirements. It combines dual springs with a damper and has a 1.437-inch outside diameter. The listing also reports 115 pounds of seat pressure at 1.700 inches, but does not state maximum lift.

The 115-pound seat pressure at 1.700 inches and 336-pound open pressure at 1.150 inches provide two reference points for evaluating the spring against a cam and valvetrain plan. Its 1.437-inch outside diameter helps with dimensional screening, while the damper-equipped dual-spring construction identifies the configuration a buyer is considering. The listing does not give a lift limit, so these pressure figures should not be treated as proof that the spring supports a 600-lift setup.

Skip it if you need a verified 600-lift rating before selecting springs; the 995-16 listing gives pressure points but no lift limit.

Consider the 995-16 when its damper-equipped dual design, 1.437-inch outside diameter, and stated pressure points align with your build. It is not a confirmed 600-lift choice from the supplied listing alone; establish lift compatibility first.

#7

7. COMP Cams 924-16

• Weight: 5.15 lb
• Dimensions: 13.4 x 3.7 x 2.8 in

Best for: Street builds with 1.900-inch height.

Why it ranks #7: The 1.509-inch outside diameter and 1.900-inch installed height are listed, but this spring has no stated lift capacity or pressure figures.

A 1.509-inch outside diameter paired with a 1.900-inch installed height defines the COMP Cams 924-16’s fit profile. Its set of 16 dual springs gives builders a complete spring set to assess for a street valvetrain, while the dual design targets strength and valve-train stability. The listing does not state a maximum lift rating.

The 1.509-inch outside diameter and 1.900-inch installed height give a builder concrete dimensions to compare with the cylinder head and retainer arrangement before assembly. COMP Cams says the dual springs use Super Cleanwire and undergo extensive quality-control testing, supporting a focus on strength, durability, and valve-train stability. Because no lift capacity or pressure figures are supplied, those dimensions alone do not establish suitability for a 600-lift cam; verify the required spring data before choosing it.

Skip it if you need a published 600-lift rating or spring-pressure figures; this listing supplies neither for the 924-16.

The 924-16 suits a street builder whose dimensions match its 1.509-inch outside diameter and 1.900-inch installed height, and who needs 16 springs. Treat those measurements as a fit starting point, not confirmation of 600-lift capacity.
