Good To Know

Q: Can I replace just one main bearing? A: Yes, this is sold as an individual bearing, though many builders replace all main bearings at once during a rebuild. Check the crankshaft and crankcase for wear before assembly.

Q: Will this fit my GTX outside the listed years? A: Fitment is stated for 2002-2003 GTX models with the 1503 engine. Confirm your model year and engine code before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
