Larger Displacement, Enhanced Torque, and MORE Power!!!

Our 1312 autparts Stroker kit is uniquely crafted for BMW and Toyota B58 Engines, both Generation 1 and 2. This kit is expertly designed to withstand up to 2000 horsepower, making it ideal for high-performance turbo or drag racing, as well as street or strip use. It is also built to accommodate high engine speeds of up to 9500 RPM.

Featuring our bespoke Custom Forged Pistons and upgraded Rods, along with the specially engineered 1312 4340 Billet Steel Crankshaft, these stroker kits have consistently proven their durability in high horsepower scenarios.

Advantages of Engine Stroking

• The increased displacement leads to higher power and torque due to enhanced cylinder volume and better combustion of the air-fuel mixture.
• A longer crankshaft stroke provides more leverage on the connecting rods, boosting torque at lower RPMs.
• Enhanced throttle responsiveness.
• Greater horsepower output.
