PISTON KIT
XR's Only performs extensive performance testing for each XR's Only Big Bore Piston Kit it offers to the public to ensure high performance and reliability standards. Piston kits are viable in compression ratios that range from the modest 10:5.1 up to 12:1. XR's Only recommends race gas with any piston kit above 11:1 compression ratio or higher.
The XR's Only Piston Kit comes with everything needed for complete top end reassembly and includes a new JE or Ross race piston, rings, wrist pin, piston clips, head gasket and base gasket.
XR's Only offers ceramic coating as an option on all of its performance piston kits, which provides a distinct advantage over conventional pistons because of its heat dissipation properties that contributes to component life. These performance pistons burn cooler and produce greater horsepower throughout the entire power band.
