Product Description

FTI GEN6C PAC Racing Dual Valve Spring Kit (Steel Retainers)

Hardcore racers and top engine builders of cylinder heads for six cylinder engines utilizing forced induction and high RPM powerplants, now have a brand new, extreme usage valve spring, spring retainer, valve lock and valve stem seal kit that extends engine RPM and boosts valvetrain performance capability. This severe duty valve spring package works best with "limited travel" hydraulic roller lifters. Some applications using tight lash solid roller lifters can also use this spring assembly.

The valve springs in each kit are carefully tension matched and all supplied components come complete and ready to install. Included are twelve CNC machined, chromemoly alloy valve spring retainers, CAD designed to deliver maximum strength and durability. Twelve precision fit spring locators are included and are designed to accurately locate the inner spring, preventing abrasion with aluminum heads. Twelve fully machined and hardened 4140 steel alloy 7-degree valve locks are also provided for superior valve stem holding reliability. Premium quality, Viton® steel reinforced valve stem seals are included for correct valve stem lubrication and oil control.
