FTI-PAC Racing - Solid Roller Dual Valve Spring Kit
This is one of the most reliable solid roller valve spring kits available for an LS or other small diameter spring pocket cylinder head. The proven PAC Racing 1300 series package is a nearly bullet-proof dual valve spring for most aftermarket cylinder heads requiring solid roller valvetrain in a tight space. High lift, high RPM camshaft designs do not scare this spring. Features Peterson's patented Pacoloy wire design and the matching titanium retainer/lock package.
The PAC Racing titanium valve spring retainers used in this kit are manufactured from the finest titanium alloy for maximum stiffness and minimal warpage. The alloy used is heat-treated and processed to stringent tolerances which makes the base material so strong that it is even used in the aircraft industry. These titanium retainers will not deform under load. From a standing idle to the most extreme RPM, this spring package will perform flawlessly and without compromise.
Hardened chromemoly spring locators are also included and are designed to accurately locate the inner spring to the valve guide, preventing abrasion with aluminum heads. Precision machined and titanium alloy "mini-8" 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.
