Sb Chevy Trpl Lwp Lower

The SB Chevy Triple Groove Lower crankshaft pulley from TRANS-DAPT is a vital component for small-block Chevrolet engine builds, modifications, and restorations. This pulley replaces the factory unit and serves as the interface between your engine's crankshaft and accessory drive system, managing serpentine belt routing for alternator, water pump, and power steering operation.

Designed to ensure proper belt alignment and reliable accessory drive function, this lower pulley features a triple-groove design that accommodates multiple belt widths. It bolts directly to the crankshaft snout and works with the upper harmonic balancer to maintain proper belt tension and prevent slippage under load. The construction material is either cast iron or ductile iron, providing durability against centrifugal forces and thermal cycling.

This lower pulley is ideal for engine builders, restoration shops, and enthusiasts performing crankshaft rebuilds or complete engine swaps on small-block Chevrolet platforms, including the 262, 283, 305, 327, and 350 engines. Its compatibility with various accessory configurations makes it a versatile choice for those looking to upgrade their engine setups.
