Moose Offroad Universal High Pressure Radiator Cap

Moose Offroad Universal High Pressure Radiator Cap raises cooling system pressure to boost coolant boiling point, preventing overheating during intense off-road sessions. Available in multiple pressure ratings from 1.6 to 2.1 bar (23-30 psi), it delivers reliable sealing for ATVs, UTVs, and dirt bikes.

This black-anodized aluminum cap features high-temperature, corrosion-resistant silicone seals that maintain system pressure while allowing safe overflow release. It fits most Japanese off-road vehicles universally, serving as a simple upgrade over stock 1.1 bar caps to support harder riding in heat-soaked conditions. Riders benefit from elevated boiling points—up to 25°F higher—enabling sustained performance without boil-over failures.

Moose Offroad (About)

Our story starts in the mid 1980’s in the shadow of the Rocky Mountains. The question in those days was how to prepare for an ever changing ride but for a core group of offroad riders it was a question of how, and out of their passion came a small offering of hard parts that would put Moose Offroad on the map. What they didn’t know was their desire to make the ride unforgettable would turn into a worldwide force of the finest collection of parts and gear for them and their machine.

In the early 1990’s, visionary Wayne Cornelius came along with distribution giant Parts Unlimited. Wayne knew Moose Offroad was good but he had a desire to make it great. His method to reach that goal was to consult the services of 8-time National Enduro Champion Dick Burleson. Utilizing Burleson’s experience the goal was to design gear that was comfortable to ride in all day rather than a 20 minute moto. That concept was launched in 1994 at the ISDE in Tulsa, Oklahoma, where a team of World-class riders emblazoned in new gear they served notice that Moose Racing has arrived on the scene.

As the 90’s continued, Moose Racing became the go to for hard parts but gear was the avenue to get brand recognition as it performed better than anything else in the market. This strategy blanketed races from the deserts in the west to the steamy woods of the GNCC with Moose Racing gear. It hasn’t been all offroad however, Moose Racing has been a staple of motocross as well. Moose Offroad is proud of its support for racers and riders at all levels from the bright lights of Supercross to the 8am races in the GNCC. Today, Moose Offroad continues the vision and strives to stay ahead of the pack, thirty plus years of blood, sweat, and gears has only made us more passionate to push on and keep evolving.
