      Upgrade to Longer Lasting Aftermarket Part. Generally, stock crankshaft harmonic balancers are not designed to handle upgraded engines. In addition, aged OE crankshaft dampers could fail anytime and that could cause a lot of problems for your Jeep Wrangler. Upgrade to Omix-ADA Crankshaft Harmonic Balancer to keep your engines running smoothly. These aftermarket dampers are designed to handle upgraded engines with faster RPMs. You don’t have to worry about engine breakdowns while on the road—whether your engine is stock or upgraded.

      Reduced Vibrations for Greater Horsepower. Harmonic Balancers or dampers are essential for keeping stress and vibrations in your engine to a minimum. Without these dampers, you’ll get damaged oil pumps, loose flywheel, split hubs among other issues. With high-quality dampers like the Omix-ADA Harmonic Balancer, you significantly reduce vibrations and make your engine more efficient, which translates to added horsepower.

      Omix-ADA Warranty. You need a better damper to handle your upgraded engine that’s why the Omix-ADA Crankshaft Harmonic Balancer is the one to beat. Backed by the company’s standard 12-month or 12,000-mile warranty, you’ll be sure you made the right call.

      Application. Omix-ADA Crankshaft Harmonic Balancer fits 2007 to 2011 3.8L Jeep Wrangler JK models.
