Small Block Chevy Gilmer Drive Pulley Kit LWP

The Small Block Chevy Gilmer Drive Pulley Kit LWP from Racing Power Co-Packaged is engineered for hot rodders and performance enthusiasts looking to upgrade their engine's accessory drive system. This aluminum pulley kit replaces the factory serpentine configuration with a Gilmer belt drive setup, a proven modification that improves underhood aesthetics while offering reliable belt tension and reduced drag. Whether you're building a street rod, restoring a classic Chevy, or optimizing a carbureted engine bay, this long water pump (LWP) version integrates seamlessly with existing cooling systems.

Crafted from durable aluminum and finished in natural (unpainted) form, the Gilmer drive pulley system uses toothed timing-belt technology to distribute power to the water pump, alternator, and power steering pump with minimal slippage and exceptional concentricity. The natural aluminum surface allows for easy polishing or painting to match your engine bay aesthetic, while the kit's precision engineering ensures proper belt alignment and tensioning. The long water pump configuration accommodates tall-deck small block installations and works flawlessly with both carbureted and fuel-injected platforms, making this a versatile choice for diverse build scenarios.

Installers value this kit for its bolt-on compatibility with small block Chevrolet engines and its ability to shed pounds compared to serpentine alternatives while improving engine bay visibility. The aluminum construction keeps weight at just 5.1 lbs, reducing rotating mass and parasitic drag on the engine. Proper installation requires attention to belt tension and pulley alignment, but once set up, the Gilmer drive system delivers years of reliable service and distinctive visual appeal that separates a serious build from stock configurations.
