LS Forged Crankshaft 4.0 STRK w/58X Reluctor

The LS Forged Crankshaft 4.0 STRK w/58X Reluctor by Brian Tooley Racing is designed for high-performance LS engine builds, where reliability and aggressive power delivery are essential. This forged crankshaft is ideal for serious engine builders, track competitors, and street enthusiasts looking to enhance their LS platforms beyond stock capabilities. Whether constructing a race engine or upgrading an existing LS setup, this crankshaft serves as a critical foundation to prevent catastrophic failures under extreme conditions.

Constructed from high-quality forged steel, this crankshaft offers superior strength compared to cast alternatives, allowing it to endure the stresses associated with high-horsepower engines and forced induction applications. The 4.0-inch stroke specification increases displacement and enhances torque characteristics across the RPM range, making it suitable for both naturally aspirated and boosted configurations. The integrated 58X reluctor ring ensures compatibility with modern LS engine management systems and aftermarket ECU tuning, facilitating precise ignition timing and fuel mapping.

Engine builders working on LS1, LS2, LS3, and LS-based platforms will find this crankshaft particularly beneficial for displacement increases and durability upgrades. Proper installation requires engine disassembly, adherence to precise torque specifications, and alignment with OEM or performance-matched components. This crankshaft is an excellent choice for those aiming to push their LS engines to new performance levels.
