LaRue Polaris Pro R Head Gasket

Head gasket thickness 0.042 inch

The head gasket is the single most overlooked failure point on a high-horsepower Pro R, and after dealing with one too many blown gaskets on stock and aftermarket options, we set out to engineer a solution that wouldn't let us down. Designed by us, for us, with the kind of clamping and combustion sealing that big power builds actually require. Built for the everyday boosted Pro R for performance and reliability. 

What sets our gasket apart is an additional ring around each cylinder that dramatically increases clamping pressure right where it matters most, sealing the combustion chamber against the kind of cylinder pressures that high-boost applications generate. It's a feature designed specifically to stop the lift-and-leak failure mode that takes out lesser gaskets when the boost climbs.

This is the head gasket sealing every Pro R we build from 200 to 800+ wheel horsepower, and it's what's holding the cylinders shut on our 970 whp Pro R. Tested and proven at power levels most platforms never see.

And it's not just for the big-boost crowd. If you're running an everyday Pro R and you want a gasket that's going to seal reliably for the long haul, trails, dunes, desert, or daily, this same gasket gives you that confidence in any style of riding. If it works for us, it'll work for you.
