Description

Proven to eliminate the OEM valvetrain's weakest link, APR valve spring and retainer kits are high performance, lightweight upgrades that increase valve control and eradicate valve float, common on many applications. The advanced design of these valve spring, retainer, and spring seat combinations are 28 percent lighter yet 20 percent stiffer and will not overpower and snap the OEM valves or erode the aluminum spring seat.

Features:

* Increase valvetrain control
* Supports higher revving applications
* Weight saving beehive spring design
* ASTM A877A OTSC round wire steel springs
* 6AL4V American titanium retainers
* 4140 heat-treated chromoly steel spring seats with black oxide coating
* 29 grams per spring
* 2 grams per retainer
* Compatible with OEM valves
* Spring seats protect against aluminum erosion in the head
