Currie Legacy Gears for the 2018 and newer Jeep Wrangler JL are forged from 8620 alloy steel for the greatest strength, precision machined for exact factory fit and quiet operation. All Currie Legacy gears are CNC lapped for reduced friction and provide quiet operation, with additional attention to detail of hand dressing each gear to eliminate any possible burrs on gear tooth edges to improve the break-in process.
