Piston Kits
PROX pistons are precision machined on the latest, state of the art CNC equipment. The same low-expansion, low-friction piston alloy is used as
is used for all major Japanese engine manufacturers. PROX Piston Kits are a first class solution to replace the original piston in your Motorcycle,
Scooter, Moped, ATV, Personal Watercraft, etc. PROX Piston Kits for sleeved cylinders are available in standard size and a wide range of oversizes.
The availability of oversizes up to 2mm significantly helps to increase the lifespan of a cylinder by offering more re-boring possibilities. PROX pistons
for plated cylinders come in standard size, as well as in A, B, C, D+ oversizes. Take advantage of the additional oversizes to extend the lifespan of
plated cylinders. All PROX Piston Kits are supplied complete with Piston Rings, Wrist Pin and Circlips, ready to install!
Connecting Rods
PROX Connecting Rod Kits are made out of the toughest alloys available today. O.E. specifications and tolerances are meticulously maintained, a
guarantee for easy installation and trouble free performance. PROX Connecting Rod Kits come complete with Crankpin, Big-End Bearing, Small
End Bearing and Washers.
Gasket Kits
Precision engineering and the use of first class materials guarantee that they meet or exceed O.E. standards.
