ATR Chassis Bones strengthen RZR’s chassis by sleeving front and rear of the main frame tubes.

Easy Bolt in Installation taking approximately 30 minutes with basic hand tools. No Welding or Cutting required!

The Chassis Bones feature ATR’s unique Torque-Lock design. Once Chassis Bones are in place you simply bolt on the machined end caps and as you torque the machine bolts down the Chassis Bone’s end features lasercut tabs that spread out, firmly clamping the Chassis Bones in place.

The Chassis Bone’s machined end pieces also feature rubber O-rings that will seal out mud and water. The machined end pieces also add to the finished look of your RZR by closing up the open, un-finished looking chassis tubes. Chassis Bones come in Zinc Chromate finish that will resist rust and corrosion.

With lift kits, larger tires, long travel kits, damaged RZR frames has become extremely common. While the RZR is a great platform to build from, the strength factory chassis really is the RZR’s Achilles’ heel.  The ATR Chassis Bones are the best available complete bolt in Chassis Strengthening solution allowing you to hit the trail or track with confidence. The Chassis Bones sleeve the entire length of the thin wall chassis tubes and greatly increase the strength of the RZR’s chassis frame where it receives the most forces from the A-Arm suspension mounts.

The Chassis Bones also prevent the RZR’s lower frame tube from getting dented from rocks or stumps. For RZR’s not running full skid plates that cover these frame tubes it can be very easy to dent the exposed tubes. Once they are dented it is easier for your chassis to bend at crucial areas. The Chassis Bones can in a lot of cases salvage dented or bent frames and re align them. This may require the use of a torch to heat up the bent / dented tubes.

Without having to go through the headache of repairing a damaged frame simply install Chassis Bones and be able to have the confidence of having a properly reinforced frame!
