Description

Greater Displacement, Enhanced Torque, and More Power!

Our 1312 autoparts Stroker kit is specially crafted for BMW S58 Engines.

Incorporating Custom Forged Pistons and upgraded Rods, along with the 1312 4340 Billet Steel Crankshaft, our stroker kits have consistently proven their reliability in high horsepower applications.

Advantages of Engine Stroking:

• The increased displacement allows your engine to generate more power and torque due to greater cylinder volume and improved combustion of the air-fuel mixture.
• A longer stroke in the crankshaft enhances leverage on the connecting rods, resulting in greater torque at lower RPMs.
• Enhanced throttle response.
• Higher horsepower output.
