Power Driven Hardened Chromoly Valve Spring Retainers for 4BT Cummins
Power Driven's Hardened Chromoly Valve Spring Retainers for 89-98 4BT Cummins are the best way to maximize the performance of 60-lb. valve springs.
These spring retainers for 60-lb. valve springs are precision machined from chromoly steel before hardening. They feature 10-degree locks and a structurally efficient design. One of the key advantages of these retainers is their ability to handle high speeds. With a capability of up to 4,200 rpm, they provide reliable and durable performance. They are remarkably lightweight, weighing just 30 grams. In fact, they are 25% lighter than the stock retainers commonly found in similar setups.
Installing these hardened chromoly spring retainers on a typical 12v head increases seat pressure slightly. Compared to the factory lock-and-retainer configuration, which results in approximately 155 lbs. of seat pressure, these retainers offer approximately 165 lbs. of seat pressure. This enhanced pressure contributes to improved valve control and overall engine efficiency.
