Chrome Crank Pulley Double Groove

The Chrome Crank Pulley Double Groove by Mr. Gasket is a precision-engineered crankshaft pulley designed for Small Block Chevy engines running serpentine or V-belt drive systems. Built for serious enthusiasts and professional mechanics, this double-groove pulley delivers reliable belt tracking and power transmission while upgrading the visual appeal of your engine bay. Whether you're restoring a classic Chevy or modernizing your existing build, this pulley serves as both a functional component and a polished centerpiece that demands attention under the hood.

Manufactured from durable steel and finished in mirror chrome, the Chrome Crank Pulley features a 6.25-inch diameter with two grooves sized to accommodate standard V-belt configurations. The long water pump design ensures proper belt tension and alignment across multiple accessories—alternator, power steering, and cooling system—without binding or slippage. Precision-machined grooves reduce friction and vibration while the chrome plating resists corrosion and maintains its shine through years of engine heat and road exposure. At 3.25 lbs, the pulley balances mass requirements for Small Block applications without adding unnecessary rotating weight that could compromise engine efficiency.

This pulley is ideal for Small Block Chevy platforms—262, 283, 302, 327, 350, and 400 cubic-inch engines—making it a universal choice for street machines, restorations, and race-prepped builds. Installation requires standard pulley removal and bolt-on fitment to the crankshaft snout; proper belt adjustment and torque specification are essential for optimal performance. Mechanics appreciate the Mr. Gasket name for quality control and dimensional accuracy, ensuring hassle-free fitment with factory accessory brackets. If you're upgrading from a worn pulley or seeking a chrome alternative to stock steel, this double-groove design delivers both aesthetic impact and mechanical reliability for long-term service.
