The LS Accessory Drive Brkt Kit LH for P/S & Alt by HOLLEY is purpose-built for LS engine swaps and builds requiring a left-hand accessory drive configuration. This bracket assembly coordinates power steering and alternator mounting on the driver's side of the engine block, eliminating fitment guesswork during complex engine conversions. Whether you're retrofitting an LS into a classic platform or optimizing accessory placement on a modern street engine, this kit delivers the precision engineering necessary for reliable, long-term operation without clearance conflicts.
Constructed from heavy-duty cast iron and steel components, the LS Accessory Drive Brkt Kit maintains OEM-grade durability and load capacity under sustained operation. The left-hand configuration positions both the power steering pump and alternator for optimal belt routing and minimal parasitic drag, critical factors in maximizing engine efficiency during high-performance or daily-driven applications. HOLLEY's engineering accounts for standard LS block mounting points, ensuring straightforward installation without modification to core engine structure or auxiliary systems.
This bracket kit serves engine builders, fabricators, and enthusiasts performing LS swaps into vehicles originally equipped with small-block Chevy, big-block, or foreign powerplants. Compatibility extends across most LS variants—including LS1, LS2, LS3, and LSx platforms—making it a versatile solution for street rods, race cars, and restomod projects. Installation pairs seamlessly with HOLLEY's broader accessory drive ecosystem, allowing builders to source matching components and achieve factory-quality assembly without trial-and-error fitment. Weighing 6.21 lbs and measuring 7.1 x 5.3 x 14.6 inches, the kit ships complete and ready for bolted installation.
