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, coil 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 BTR part number SP002/SK002 for roller rocker applications.
