R1 Industries carries the best aftermarket side by side frame stiffeners and accessories for your Polaris RZR, Can-Am Maverick X3, Kawasaki KRX, and many more!

Shop trusted UTV parts and side-by-side accessories including doors, seats, windshields, tender springs, and tires, plus brand-specific upgrades for Polaris, Can-Am, and Honda.

Customers also searched for: UTV lift kits, dual-rate spring kits, ride height adjusters, shock spring replacement, off-road windshields for Polaris RZR, Can-Am Maverick suspension upgrades, Honda Talon comfort mods, UTV seat harnesses, and mud/trail tire setups.

Updated for 2025 models and the latest UTV accessories.

Do tender springs really help restore ride height?

Yes. Quality tender springs reintroduce preload and typically recover 2–4 inches of practical ground clearance when properly set up.

Which UTV brands do you carry parts for?

We stock parts and accessories for Polaris, Can-Am, Honda, Kawasaki, and Yamaha, with model-specific fitment filters on collection and product pages.

What’s the best way to make my UTV ride smoother?

Start with fresh tender springs and correct preload. Pair with the right tire setup and consider seat/harness upgrades for comfort and control.
