Summit Racing Equipment® Trapezoidal Tech Pro LST Pistons

Not Yet Reviewed

Summit Racing Trapezoidal Tech Pistons and Connecting Rods are designed for high boost and high rpm and the first to be designed as a matching system. Compression and tension loads are analyzed to maximize the Wrist-Pin's required bearing area where it's needed most. The resulting pin is Shorter/Stiffer/Lighter and the piston becomes lighter and stronger as well.. This reduces loads on the rods, bearings and crank for increased durability and saves on balancing costs.
