      Specs. When the idler pulleys that your Wrangler's engine belts run on start to squeal loudly, it is a sign that they will soon freeze, damaging the belts, the drive bearings, and possibly other components. Omix-ADA's Idler Pulley is a direct fit replacement for the stock pulley, providing years of smooth, silent use and keeping your belts humming busily away. Install these quality pulleys for superb, quiet, reliable function and to ensure your belts continue to work properly.

      Construction. Omix-ADA manufactures this solidly constructed Idler Pulley out of high strength steel and finishes it with a black powder-coated finish, ensuring that it remains immune to rust. This is a serpentine style pulley and does not include a bracket or idler cover. It is designed to work with JK and JK Unlimited models with the 3.8 liter engine. The part is covered by Omix-ADA's typical 5 year warranty against all types of defects.

      Application. Fits 2007-2011 Wrangler JK and Unlimited models.
