TSP 418 or 421 C.I.D. LQ4/LQ9/LY6 Rotating Assembly

Texas Speed & Performance rotating assemblies offer the best durability with the best pricing available! We offer both a 4.10" and 4.125" stroke crankshaft, which we have listed. All of the piston sets listed will work with either stroke crankshaft; The 4.10" stroke crankshaft will require a slightly shorter block deck height vs. the 4.125" in order to achieve a "zero deck" setup. You can choose from a variety of upgrades for the crankshaft, connecting rods, and pistons! FYI, All Wiseco piston sets will come standard with their steel top/napier 2nd ring set! Bearings are not included in the base price but can be added to your rotating assembly package. Give us a call, and we will be happy to spec out a rotating assembly that will match your needs!
