The Texas Speed 4.10" Stroke Forged Crankshaft is machined from 4340 steel for LS engine builds that need more durability than a factory casting offers. Texas Speed rates the crank for engines up to 950 horsepower and cuts every TSP crankshaft with a 2.100" rod pin and a .125" fillet radius, with a finished weight of 52 lb. It uses a 6-bolt rear flange and a standard snout for wet sump oiling.
A 4.10" stroke is the step beyond the common 4.000" stroker crank and is used for larger-displacement LS builds. The crank ships with GM short and long crankshaft keyways, and the buyer selects a Scat 24x or GM 58x reluctor wheel at ordering to match the engine's crank sensor and controller. Texas Speed recommends ACL bearings with its crankshafts and also offers complete rotating assemblies built around this crank, with balancing available, for buyers who want the crank, rods and pistons matched as a set.

FAQ
What engines does the Texas Speed 4.10" stroke forged crankshaft fit?
It is a 6-bolt rear flange, standard snout wet sump crankshaft for Gen III and Gen IV GM LS blocks, with a 2.100" rod journal. Texas Speed sells it with a 24x or 58x reluctor wheel to match the engine's crank sensor and ECM.
Should I choose the 24x or 58x reluctor wheel?
Choose the reluctor that matches the vehicle's engine controller. Gen III LS engines (1997 to 2006 style ECMs) use a 24x signal and Gen IV LS engines use 58x. The Scat 24x or GM 58x wheel is selected when ordering this crankshaft.
How much power is the 4.10" TSP crankshaft rated for?
Texas Speed rates its forged 4340 steel crankshafts, including this 4.10" stroke version, for engine builds up to 950 horsepower, with a 2.100" rod pin and .125" fillet radius for strength.
What bearings should I use with this crankshaft?
Texas Speed recommends ACL bearings for its forged crankshafts. Clearances should be checked during assembly as with any aftermarket crankshaft.
Is this crankshaft for wet sump or dry sump engines?
This version has a standard snout for wet sump oiling and a 6-bolt rear flange. It is not the long-snout dry sump design or the 8-bolt LSA flange.
