Part #


Presenting RT Pro’s weld-in chassis gusset kit for the RZR 800 50″ or RZR 800 S/4. This is the most comprehensive kit you will find, and at the best price! We’ve been racing the RZR since they day they came out. We’ve found the weak points and we know how to fix them, PERIOD.

This kit, when combined with our other bolt-on gusset kits, takes care of everything you need to make your RZR race ready or just plain indestructible on the trail. It covers all the failure points we found on the original RZR 800 chassis through years of racing in every series and environment. It covers the front and rear suspension pivot mounts by properly gusseting them for maximum strength. It also includes gussets for critical points on the main chassis we found failures in through the years of hard landings, crashes and roll-overs. If you’re building a RZR 800 50″, S or 4 seater to abuse it and don’t mind a bit of work, this kit is for you.

Kit is priced WITHOUT weld washers for the A-arm pivot points. If you want these washers you can add therm to your order HERE. The stepped washer kit is a machined part which makes the actual shear surface one continuous diameter. We highly recommend using the stepped washers on all a-arm pivot tabs for maximum strength and rebuilding the typically deformed holes in the chassis. To cover all the pivot holes on the RZR 800 chassis when installing this gusset kit you will need 18 stepped washers. The front tab for the front upper a-arm IS covered by this gusset kit which reduces the washers needed by 2.

NOTE: All kits come complete with some gussets to cover the 2008+ RZR 800 50″, S and 4 seat chassis. Some may not be needed on newer year RZR’s because Polaris added some gussets to the chassis through the years.
