Upgrade the valve train in your Hemi 6 with a serious roller rocker package designed for high performance street and street/strip engines. This 1.8 ratio Ultralite-Pro conversion kit is suited to Chrysler, Valiant and Charger Hemi 6 engines using a factory style cylinder head, including 215, 245 and 265 applications.

The higher 1.8 rocker ratio helps increase valve lift without relying solely on a more aggressive camshaft, making it a popular option for engines chasing stronger breathing and improved top-end performance. The Ultralite-Pro design reduces rocker nose weight compared with the factory pressed steel rocker system, helping improve valve train stability at higher RPM while maintaining strength where it matters.

These are full roller, stud mount rockers with hardened chrome moly roller tips, oversize trunnions and caged bearings to reduce friction and wear at the valve tip. The aluminium rocker bodies help manage top-end heat, while the adjustable posi-lock style setup allows correct valve train adjustment for hydraulic or solid lifter combinations.

As with any high performance valve train upgrade, pushrod length, spring clearance, retainer clearance and geometry should be checked during assembly.
