Overview
The SCAT Series 9000 4 inch stroker crankshaft is a strong, practical upgrade for small block Chrysler 318 and 340 engine builds where extra capacity and torque are the goal. With its 4.000 inch stroke, this crank is well suited to street performance and mild competition combinations, giving your Mopar small block the added leverage needed for stronger low and mid-range power.
Manufactured from cast steel, this crankshaft is a sensible choice for enthusiasts building a tough street engine without stepping up to a full forged race crank. It is precision ground and micro-polished for accurate bearing surfaces, helping promote reliable oil film control and consistent operation when matched with the correct bearings, rods, pistons and clearances.
The 2.125 inch rod journal diameter suits common small block Chrysler performance rod combinations, while the standard snout and 2-piece rear main seal configuration make it appropriate for traditional LA-series style engine builds. It is designed for internal engine balance, however any stroker engine assembly should still be professionally checked and balanced as a complete rotating assembly before final fitment.
This is a quality choice for Valiant, Chrysler, Dodge and Plymouth restorations or performance builds where you want more cubic inches while keeping a classic small block Mopar foundation.
