Product Description

New 1.260" Diameter Circle Track, Race or Hot Street Valve Springs

Drop in type SBC Hi Lift Valve Springs, Circle Track

Replaces OE Race Saver Springs

 

These drop in springs were manufactured for use with Race Saver 305 spec engines.

Manufactured in the USA by Peterson Spring.

These are not cheater springs, they are direct replacements with the proper loads and markings; each spring has the correct red paint stripe from the manufacturer.

Since Peterson was the original supplier to the cam company who supplies springs to the folks who assemble and sell race saver 305 circle track heads, those who need springs can be assured they're going to get the correct spec'd springs by ordering a set of these from us.

No need to pay more for springs which belong to a class where costs are supposed to be "affordable".
