SP602EC Economy Valve Spring Kit

For the racer on a tight budget, this is a better option than the hit-and-miss consistency of a box of springs from GM.

This NEW set of 16 springs is matched at exact poundage.

These springs go through the entire test cycle that our SP602+ springs do but fall short of our standard criteria for upper RPM stability.

We highly recommend adding keeper set 12495503 to your order as they are not included.

Note: Economy (EC) springs may need changed more frequently than SP602+.

All springs are from the GM 19154761 and in no way aftermarket or 'cheater' springs.
