2008-2010 Dodge Challenger Valve Springs, Retainers, and Accessories

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.

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.
