Overview

The Halferland Performance lightweight crank pulley is designed for Honda/Acura J-Series engines with single accessory belt layouts. It is 84% lighter than the stock OEM pulley, significantly reducing parasitic loss in the drivetrain. This pulley offers immediate gains of 8-12 WHP and is a 100% straight swap, plug-and-play installation. It features a stock diameter and does not cause charging issues associated with underdriven pulleys.

Show original supplier description

The HalferLand Performance HLP V.2 lightweight crank pulley is a performance upgrade for Honda/Acura J-Series engines equipped with a single accessory belt. Weighing in at just 1.4 lbs, this pulley is an impressive 84% lighter than the stock OEM component. This significant weight reduction directly contributes to decreasing parasitic losses within the drivetrain, freeing up engine power. Installation is designed to be straightforward, described as a 100% straight swap and plug-and-play process. The pulley maintains stock diameter to avoid undercharging issues sometimes associated with underdriven pulleys. This component is compatible with Gen 2, Gen 3, and Gen 4 J-Series engines, with specific engine code fitments available in a dropdown selection. It is crucial to note that this pulley is exclusively for single belt drive configurations. If your J Motor utilizes two accessory belts, this specific pulley will not fit. HalferLand Performance plans to release a pulley for Gen 1 motors with dual belt setups at a later date.
