The RT Pro RXP Arm Kit is a direct bolt-on replacement front arm kit which maintains the use of the OEM length shocks and axles while drastically improving the steering and handling characteristics. The 2012+ RZR XP 900 came with improved geometry over the 2011 version. Our kit improves even further than the advances of the 2012. The RT Pro RXP Front Arm Kit fits all years and delivers better steering characteristics than any model RZR XP to date.
In an effort to minimize weight gains, we’ve developed a new process of manufacturing our lower A-arms. The result is a 100% boxed sheet metal arm with higher ground clearance and 35% less weight than equivalent previous designs. We’ve also found another way of substantially reducing the overall weight of the kit by building the upper arms with a simple, minimalist tubular design which results in a stylish and indestructible design which weighs almost the same as the OEM components. This complete kit only adds 12.5 lbs. to the machine over stock weight arms. Even with the reduced weight, The RT Pro RXP Arm Kit is just as strong as any of our previous designs and stronger than any other arm kit on the market for the RZR XP 900.
All RT Pro suspension systems eliminate the dangerously weak OEM ball joints with our proven FK Bearings heim joints. Don’t ever let someone tell you the OEM ball joints are just as strong! It is simply not true. This kit uses the same proprietary design “spindle adapters” as we use in all of our arm kits on both the upper and lower arms. After years of testing and experience we feel these are THE strongest solution in the word to connect heim joints/mono balls to Polaris OEM spindles and eliminate the weak OEM ball joint set up. The lower heim joint on the RXP Arm Kit is a massive 3/4” chromoly unit. It affords the user unmatched strength but also easily adjustable camber settings to fine-tune the performance to their individual preference. The upper arm uses 7/8” diameter chromoly mono-ball design which increases the strength of the tubular upper arm design while it simplifies the initial setup for the end user.
This kit fits all RZR XP 900 models and years!
Dust Cap Option: For those who run in a lot of mud we recommend our Dust Cap Upgrade. These are NOT required but they are an option for those who want it. The mono balls we use have teflon linings in them so they may be run dry but some people like to grease their joints for certain applications and these caps also give you a clean way to do this if desired.These caps are for the upper arms only. Caps are installed by tapping them in place. To remove they must be pried out. The upgrade on this page is for a pair of caps with “press-in” grease zerks.
