Reduce friction. Improve durability. Protect under load.
Wrist pins operate under extremely high load with constant oscillating motion, making them one of the most critical wear points in any engine. Limited lubrication and high contact pressure increase the risk of scuffing, galling, and long-term wear.
WSX coatings provide an ultra-low friction surface that helps protect against metal-to-metal contact, especially during startup and high-load conditions. For complete piston assembly protection, pair with our piston coatings.
Built for the unique stress of back-and-forth movement.
Protects under extreme pressure and RPM.
Works before full oil pressure builds.
Maintains factory tolerances without modification.
Unlike rotating bearings, wrist pins experience oscillating motion — rocking back and forth under extreme pressure rather than spinning continuously. This creates unique wear patterns that standard lubricants can't always protect against.
WSX coating is an ultra-thin, extreme-pressure dry film lubricant. It creates a slick surface that reduces friction at the pin-to-piston and pin-to-rod interface, protecting against scuffing when oil film breaks down.
The coating is so thin it doesn't affect clearances — making it ideal for tight-tolerance engines where every thousandth matters.
It reduces friction between the pin, piston, and connecting rod, helping prevent wear under high load and during cold starts.
Negligible thickness. The coating is extremely thin and designed to maintain proper clearances.
No. It benefits both high-performance and street engines where durability and reduced friction are important.
Yes. We recommend coating both for complete piston assembly protection — pistons for heat and friction, pins for contact wear.
When properly applied, WSX coatings are extremely durable and designed to last the life of the component.
Reduce friction and wear where it matters most with precision-applied wrist pin coatings.
