89-98 Dodge 5.9L 12 Valve Cummins PDD Hardened Chromoly Spring Retainers

PDD’s Hardened Chromoly valve spring retainers are the best way to maximize the performance of 60lb valve springs.

These Chromoly 60lb valve spring retainers are precision machined from chromoly steel before hardening. They feature 10-degree locks and a structurally efficient design. This results in a lock & retainer assembly capable of up to 4200 rpm, at an assembly weight of only 30 grams, 25% lighter than stock.

When installed on a typical 12v head, they deliver a slight increase in seat pressure as well. A factory lock & retainer setup results in approximately 155 lbs of seat pressure. These deliver approximately 165 lbs of seat pressure.
