      Description

      Over time all internal engine wear surfaces become worn. This is true for crankshaft journals, connecting rods, camshaft lobes, piston rings, bearings, etc. When rebuilding a worn out engine you'll need to replace them all in order to regain the engine's original performance. And, let's face it, Jeep's need all the power we can get. We offer new high quality replacement engine parts to get your Jeep back on the road. This replacement main bearing set fits 07-11 Wrangler JK / JKU models equipped with 3.8 liter engines with standard crank. Replaces OE 5175980AA. This standard size main bearing set fits the 3.8L engine used in 2007-2011 Jeep Wrangler.
