A-Premium Engine Serpentine Belt Drive Kit for Jeep WJ Grand Cherokee (1999-2004) & TJ Wrangler (2000-2006) 4.0L

Upgrade your Jeep’s belt system with the A-Premium Serpentine Belt Drive Kit

Built for the rugged reliability that Jeep owners expect, this A-Premium engine serpentine belt drive kit is designed to fit the 4.0L V6 powertrains in Jeep WJ Grand Cherokee models from 1999 to 2004 and TJ Wranglers from 2000 to 2006. The kit places a sturdy new belt, tensioner, and tensioner pulley at the front of the engine, where a single loop coordinates multiple accessories. When the belt is fresh and the tensioner spins freely, you may notice smoother transitions between components and a dependable rhythm as you drive. While no replacement can guarantee performance, fresh components can help your engine run in its intended sequence and reduce belt-related concerns on daily commutes or longer trips.
