      Smooth Engine Performance. One of the most critical parts of your engine is the main bearing set that supports the crankshaft. It allows for the free rotation and movement of the crankshaft, cushioning against harmful friction. Bearing failure causes catastrophic issues on your engine, which is why regular the inspection and replacement of parts is essential. This Main Bearing Set is the premium choice for aftermarket parts. It’s engineered for a precision fit and maximum durability, both important factors when choosing your replacement bearings.

      Fits Line Bored Engine. A line bored engine block would need oversize main bearings to compensate for the loss of ground material from the bore. Fortunately, this Main Bearing Set is actually a 0.10” oversize bearing set. The outside diameter of the bearing is thicker than a standard main bearing to fit the thinned bore it faces. With the modified bearing, you could still achieve an optimal clearance between the bore and the bearing for improved engine performance.

The company consistently delivers only quality automotive parts and that includes this Main Bearing Set.

      Application. This Connecting Rod Bearing Set fits 1991 to 2006 4.0L Jeep Wrangler YJ and TJ models.
