BTR PLATINUM GEN V LT1 DUAL SPRING KIT - .660" LIFT - TI RETAINER - STOCK GUIDES - SK007/0545/BB

The BTR Platinum Spring Kit would be inducted into the LS Aftermarket Hall of Fame if such a thing existed. Whether you’re putting together a daily driver with a mild cam, a 600 hp N/A stroker, or a turbocharged 1000 hp brawler, our Platinum Spring Kit will make sure your valves are right where your cam wants them to be at all times. With that said, when the Gen V LT engines came out, we knew our Platinum Springs would be right at home on the direct injection platform with the correct supporting parts. They are designed to be used with stock rocker arms. This is a drop-in kit for Gen V LT1, L83, and L86 engines with stock powdered metal guides.
