      Ensures Smooth Crankshaft Movement. The crankshaft main bearing helps keep the crankshaft in the proper position while also letting it rotate smoothly. With such an important task, worn or damaged crankshaft main bearings should be replaced immediately to prevent catastrophic engine failure. With this Crankshaft Main Bearing, you can replace your Jeep’s factory discontinued part and keep it running like it’s brand new. Note that the bearing is sold separately and your Jeep will need 1 for each cylinder.

      High-Quality Construction. The replacement Crankshaft Main Bearing is precision-machined from high-grade materials to meet OEM specifications. This provides the bearing with excellent fit, functionality, and reliability that match the OE part.

      Professional Installation Recommended. The Crankshaft Main Bearing is designed as a direct fit replacement for a clean and hassle-free installation. However, due to the complex tear-down required to replace the main bearings, professional installation is recommended.

      Backed with 12-Month/12,000-Mile Warranty. The Crankshaft Main Bearing is guaranteed to be free of defects in material or workmanship. This warranty is only valid for the original purchaser and exclusions will apply.

      Application. The standard-sized inch Crankshaft Main Bearing is designed to fit 1987-1990 2.5L or 4.2L Jeep Wrangler YJ models.
