1994-1996 Impala SS Valve Springs, Retainers, and Accessories

If you need assistance in selecting the springs that are right for you, Thunder Racing has spent a great deal of time researching numerous combinations of valve springs from various manufacturers.  Our  Power Technology PT-200 valve spring tester has been used to measure seat pressure, open pressure, coil bind height, and spring rate for each type of valve spring that we offer.  For an additional charge, we also have the ability to provide each customer with a printout outlining each of these parameters for your specific valve springs.

Incorrect valve springs can spell disaster for your engine.  Valve springs must be carefully selected to match your camshaft to maximize power.  No one understands this better than Comp Cams!  Comp Cams manufactures a wide variety of valve springs and retainers to meet your engine building needs.  Comp Cams valve spring retainers, locks, and spring locators are available to finish out your valve train with parts from a company you can trust.

Theoretically, it’s possible for almost anyone to make a good valve spring once. Even with rather “loose” manufacturing and quality control standards, they can simply be lucky. But, there is only one way to do it right every time. You must of course begin with the finest valve spring wire obtainable, wind it precisely on modern equipment and employ the special processing techniques necessary for maximum load retention. Even this however, is not enough, because valve springs that are routinely manufactured this way can and do experience failures. The only way to be absolutely certain every batch of endurance racing valve springs is “worthy” is to test them. Isky's 1,000 Racing Mile Endurance Test Standard is such a test, the first and only one of its kind in the industry.  Isky tests every batch of every part number they produce to ensure they deliver the absolute maximum endurance possible in a racing valve spring.

The easy-to-use, custom design of the new COMP Cams® Valve Spring Compressor for LS Engines enables the effortless removal of either one or two valve springs at a time, without the hassle of first having to remove the rocker stand or any of the other installed rockers.

The tool works on all GM Gen III/IV LS-type engines, both with cylinder heads installed or with the cylinder heads off. The simple design facilitates easy usage in vehicles where other tools are incapable of reaching the tight spaces. This innovative Valve Spring Compressor is a must have for all LS engine builders and enthusiasts.
