![]() The stock hub assembly bolts right onto the Grounded 4 arms with the stock hardware. The arms and rods showed up raw, so we powder coated them to match the RZR. We have raced this machine several times and want to keep adding strength to it. The setup weighs just over 3 pounds more than stock. ![]() At the front end the pivot bearing and tip are much beefier than stock. The stock hub assembly will bolt right up to the Grounded 4 trailing arm. Stock trailing arms sell for just over $800 per pair. To replace the stock radius rods with OEM parts, you would spend over $525, and they are not adjustable. The radius rods are made from 4130 steel with 5/8-inch uni-balls on the bottom arm and adjustable heim joints up top in case you want to adjust the camber at the rear end. We made a pair out of strong semi truck mud flap material that cost us $10. Each arm accepts Grounded 4 mud flaps, or you can build your own. ![]() The arms are 3.2 pounds heavier than stock but appear to be way stronger. All the parts are Tig welded together, giving them a clean look. The arms are stock length and made from DOM steel tubing, with 4130 steel plates, gussets, shock and sway bar mounts. To try out the Grounded 4 products, we ordered a set of rear trailing arms and radius rods for our Fox Edition RZR XP 1000. It has a more angular look and is made from stronger 4130 steel.

So far the Grounded 4 RZR XP 1000 product line includes snap-in radiator grills ($120), trailing arms ($1575), mud flaps ($75), radius rods ($499) radius rod plates ($70) and A-arms ($1595). This SoCal based company has had decades of ATV racing experience, spent years perfecting the Yamaha Rhino, and is now transferring that knowledge into high-performance UTV products. Many companies offer replacement trailing arms and radius rods, and this month we are taking a look at a company called Grounded 4. If it’s too late and you have already ruined a corner, then you should probably consider new trailing arms, as well as stronger radius rods. To prevent this failure, be gentle on those rear corners and strengthen your components. When this happens, it could also take out the entire trailing arm, rear shock and axle. Drive extra hard into a square-edged berm or land sideways on one rear tire, and one or more radius rods can fail. Besides the drive belt, the easiest part to damage or break on a RZR XP 1000 is the rear radius rods.
