COMP Cams 09-18 Dodge 5.7/6.2/6.4 HEMI 0.63in Lift Conical Valve Spring Kit

Starting with the .630-inch maximum lift capability, this COMP Cams Conical Valve Spring Kit is built for Dodge HEMI engines from 2009 through 2018. This kit is designed to handle the demands of high-performance and racing applications, offering improved stability at higher engine speeds. It's a comprehensive solution that removes much of the guesswork when upgrading your HEMI's valvetrain for more power.

The conical shape of these springs allows for a smaller base diameter, which means they can be used with a lighter, stronger Chromemoly retainer. This design contributes to reduced mass in the valvetrain, helping to prevent valve float and ensure consistent operation even when the engine is spinning fast. This kit is engineered to work with your stock cylinder heads, meaning no additional machine work is required for installation, making it a straightforward upgrade for many Dodge, Chrysler, and Jeep vehicles equipped with the 5.7L HEMI engine, as well as larger displacement variants.

When you're building a more powerful HEMI, ensuring the valvetrain can keep up is crucial. This kit includes everything you need to get the job done: the conical valve springs themselves, along with the necessary valve locks, seals, seats, and Chromemoly retainers. It's a well-built package designed to give you confidence in your engine's performance and reliability under demanding conditions.
