Product Design Philosophy
Aluminum alloy split collets for 4HK1/4JH1/4JB1/4JA1 engines. Precision-machined to lock valve spring retainer onto valve stem, ensuring reliable valve operation at high RPM.
How it works
Two-piece split collets fit into a groove near the valve stem tip. When the spring retainer is installed, the collets wedge tightly, locking the retainer and spring to the valve stem.
Problems the product can solve
Fixes valve drop, spring retainer loosening, and engine misfire caused by worn or broken collets. Restores secure valve retention and prevents catastrophic engine damage in NPR trucks.
