Description
Replaces Worn or Faulty Main Bearings. The Jeep’s crankshaft main bearings are subjected to a lot of abuse and it’s no wonder that over time they’ll wear out or even fail. Thankfully, you can replace your Jeep’s factory-discontinued standard-sized bearings using the OMIX Crankshaft Main Bearing Set. It features a set of direct fit bearings for a hassle-free installation.
High-Quality Manufacturing. OMIX has been providing quality OEM replacement parts for over 50 years. The OMIX Crankshaft Main Bearing Set is made with their usual high-quality manufacturing processes. The precision-machined bearings have the excellent fit, functionality, and reliability that match the OE parts.
Professional Installation Recommended. While the Crankshaft Main Bearing set is a direct fit replacement, the process to get to the crankshaft is rather complex. It’s highly recommended that the installation of the replacement is performed by a professional mechanic.
OMIX 5 Year Warranty. OMIX warrants to the original purchaser that the Crankshaft Main Bearing Set is free of defects in material or workmanship. Exclusions will apply.
Application. The OMIX Crankshaft Main Bearing Set of standard-sized bearings is designed to fit 1987 to 1990 4.2L Jeep Wrangler YJ models.

I got into Jeeps at an early age, as a child around 3-4 year of age my parts got me a power wheel Jeep and the rest was history. Growing up I always wanted a Jeep, from the day I started driving I spent my days behind the wheel of a Jeep branded vehicle, which has not changed.
