CT Race Worx Polaris RZR Pro R A Arms, Turbo R A Arms

Lower Arms – 

The construction off this arm consists of a mix of .115″ and .135″ Grade 50 steel. The front face of the arm has a 45 degree face on the bottom edge so when you hit that rock or obstacle it will help push it up and over, and let us add these arms don’t mind being beat on things, they beg for it. The internal structure of this arm is very unique, it features an I beam style construction that is roughly 13″ long and starts at the uniball cut and run past the shock mount. The shock mount is machined into this chunk of steel and houses a WSSX12T FK uniball with stainless steel spacers. The bushing barrels are created to mimic the factory measurements perfectly, except we added 6mmx1 thread and we include grease fittings for serviceability without having to take the front suspension off to lube the pivot points on the chassis. At the spindle side we changed out the failure ridden factory ball joint for an FK WSSX14T uniball which is the top of the line 7/8″ FK spherical bearing. The uniball is held in a custom uniball cup that we machine here in house from 4130 chromoly. To finish off the spindle side of things the spindle pin is made and heat treated in house from 17-4 stainless to H900 standards and holds the factory geometry and pivot point location perfectly. Steering stops have also been added to the arms in the factory location to keep the outer CV within its tolerances through the suspension travel and steering angles.

Upper Arms – 

We started with our boxed a arm design which has be proven for a decade throughout our product line. The brake line bungs in the arm have a sealed bottom, they are not exposed into the internals of the a arm and they utilize 6mm hardware that we supply. The CT logo on top of the arm is cut from stainless steel and can be left bare, polished or powder coated depending on the look you’re going for. The bushing barrels are created to mimic the factory measurements perfectly, except we added 6mmx1 thread and we include grease fittings for serviceability without having to take the front suspension off to lube the pivot points on the chassis. At the spindle side we changed out the factory ball joint for an FK JMX14T-770 joint which is the top of the line 7/8″ FK Rod End. The joint is secured and kept in place by a pinch clamp that we machine here in house made from a block of 4130 chromoly. A 5/16″ Grade 9 bolt squeezes on the threads to make sure it doesn’t move, also this design doesn’t keep you wondering if a jam nut will break loose since there is no jam nut. The joint is threaded in and only leaves about 4 threads exposed, this allows you to add or subtract chamber to your likings or if you’re dealing with a tweaked frame and you’re trying to get your tires upright perfectly again. To finish off the spindle side of things the spindle pin is made and heat treated in house from 17-4 stainless to H900 standards.
