THESE ARE FOR STOCK ROCKERS

.660″ Lift Dual Polished Springs, these are a perfect upgrade to standard “Gold” springs and fit most aftermarket LS spring components.

Spring specs are 155 lbs @ 1.780″, 380 lbs @ 1.180″, 400 lbs @ 1.130, coild bind @ 1.070″, set of 16.

Matching retainers, locators and seals MUST be used with dual springs. Failure to use the required components can result in engine failure!

SP001/SK001 springs are designed for use with stock rockers.

Heavier roller rockers require more spring pressure to maintain control of the valve train.

We recommend our SP002/SK002 for roller rocker applications.
