Good To Know

Q: What does a .040 oversize piston kit mean? A: It means the piston is sized to fit a cylinder bored 0.040 inches over stock, which is used to correct wear or scoring. The cylinder must be machined to match before installation.

Q: Will this kit fit my 2009-2014 TRX 400X? A: It is listed for those model years, but the cylinder must be bored to the matching .040 size first. Verify your engine's current bore and serial number 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.
