GM 3.622" Stroke LSx Crankshaft

GM Stock 3.622" Stroke Crankshaft

Replaced PN: 19431872

Factory replacement crankshaft for LS1, LS6, LS2, LS3, L99, LQ4, LQ9, and LY6 GM engines. It has the 6-bolt rear flange for most of the popular applications. It will NOT work with the LSA or LS9 engines since these engines require an 8-bolt and 9-bolt rear flange, respectively. This crankshaft can also be used in engines with forged pistons and connecting rods without modification! It comes standard with a 58x reluctor wheel on it, but we can swap it to a 24x reluctor wheel if you need.
TSP will not install reluctors unless also balancing, as it must be removed to achieve proper balance.
