コレクション: BMW Stroker Kits by 5150 AutoSport

5150 BMW Stroker Kits are engineered to deliver maximum performance, strength, and reliability for BMW enthusiasts who demand more from their engines. Each kit is designed with premium, race-proven components, including forged pistons, forged connecting rods, and a precision-machined 5150 billet steel stroker crankshaft. Together, these parts increase engine displacement, torque, and horsepower while ensuring durability under the most demanding conditions.

Whether you’re building a high-performance street car, a dedicated track machine, or a forced-induction setup, our BMW stroker kits provide the foundation for serious power gains. The longer stroke crankshaft improves leverage and low-end torque, while forged internals withstand the stresses of high RPM and boost pressure. Drivers benefit from improved throttle response, stronger midrange power, and the ability to reach higher overall output without sacrificing reliability.

Designed specifically for BMW applications, 5150 BMW stroker kits are available in multiple configurations to meet your build goals. From naturally aspirated to turbocharged projects, our kits give you the strength and performance advantage needed to take your BMW to the next level. Built for racers, tuners, and performance shops, 5150 BMW Stroker Kits are the proven choice for serious engine upgrades.
