Description
The CP Carrillo M9039A forged piston kit is designed for Sea Doo RXP and other 215, 255, and 260 4TEC models that want a stronger bottom end and a higher 9.5 to 1 compression ratio. Built for 100mm standard bore and 63.4mm stroke 1494cc engines, this kit keeps displacement stock while raising compression to deliver sharper throttle response and stronger mid range power. When paired with proper tuning and fuel, it offers a potent blend of reliability and performance.
Each M9039A piston is part of the CPK9039A configuration and is intended to work with rod 5476, 905 2250 19CP3C wrist pin, 905X073 SWL locks, CPN 3937 ring set, and H30220305 gasket. The forged design uses reinforced ring lands and a robust crown to handle the demands of boosted operation. This makes the kit a smart upgrade for riders who want more power without sacrificing durability.
- Fitment 2005 2015 Sea Doo RXP 215, 255, 260 turbo or supercharged engines with 100mm standard bore.
