2025–26 Polaris Matryx Tunnel Stiffener & Rear Bumper Kit
Built in Canada by CR Racing for the newest Matryx chassis.
Engineered specifically for the updated 2025–2026 Polaris Matryx, this tunnel stiffener + rear bumper system reinforces the rear tunnel for fuel racks, tunnel bags, hitches, and backcountry towing. Polaris changed the suspension bracket and step pattern on the 2025–26 models, so we redesigned our plates to match the new layout.
CNC-cut from 6061-T6 aircraft-grade aluminum and tied directly into the bumper, this system strengthens the weakest point of the tunnel and adds reliable pulling power without excess weight.
Note: Bumper shape remains the same. Photos may not yet show the updated 2025–26 plate design.
