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 155 outside the listed years? A: Fitment is stated for 2008-2013 and 2015-2016 GTX 155 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.
