As racers, we are always looking for that "edge". Light weight improves performance in many ways, but a broken part is a DNF (or leaves you stranded along the trail). Thunderhawk Performance looked carefully at the suspension design and dynamic loads when designing this radius rod kit, and then we selected the best material for the application. Since the loads on the upper and lower radius rods are different, we chose to use two different materials to optimize the design of these upper and lower radius rods. In doing so, we were able to reduce the weight of this radius rod kit by 1.9 lbs compared to the spindly, stock radius rods.
We did not build a high-clearance lower radius rod design as these are inherently weaker, prone to bending & flex and many have a nasty habit of damaging the frame. A straight radius rod is superior in all circumstances except abuse (yes, bending a radius rod when you drive into a big rock is abuse). Now, if you ride creek-beds (with rocks hidden below the waterline) or if you are a rock-crawler, then we understand the need for high-clearance radius rods. But, most trail riders should consider straight radius rods for their strength and durability under normal trail conditions. Thunderhawk's radius rods are race-tested, and trail-proven! You won't find a finer set of radius rods for the RZR.
Thunderhawk's lower radius rods are fabricated from 1.25" diameter x 0.095" wall DOM steel tubing with chrome-moly ends. DOM tubing was selected for it's strength & durability to withstand the under-car environment and normal trail exposure. The larger diameter provides additional strength and stiffness without adding much weight.
Thunderhawk's upper radius rods are made from 1.25" diameter x 0.160" wall 6061 aluminum that features swaged ends to create a one-piece rod without tooling marks from machining that can lead to cracking. This tubing was selected because it increases the strength to resist common failures (bending during suspension compression) while reducing weight.
To complete this kit, we also chose to use stainless steel spacer bushings which are stronger than aluminum and will not rust like steel. The rod end bearings used in this kit are the strongest available with a 19,750 lb. static load rating and they feature a high- strength 4130 chrome-moly body, a hard-chrome plated bearing and a nylon insert. The radius rods feature a durable black powdercoat finish. This radius rod kit installs in about 60-90 minutes. Kits are available to fit all 2014 & newer RZR XP 1000 and XP Turbo models. Owners of 2017 model year XP 1000 RZR's will need to verify the size of the radius rod bolts used on their machine - 10mm bolts have a 15 mm hex head and 12 mm bolts have an 18 mm hex head. We do not currently offer a kit to fit RZR XP Turbo S (72" wide model). Made in USA.
NOTE: We strongly recommend upgrading the factory four-bolt radius rod plate to a plate with a double-shear design on all RZR's. If you are upgrading the radius rods, that indicates that a double-shear plate should certainly be added as well. Thunderhawk Performance offers a plain double-shear radius rod plate, and also offers our rear 2" receiver hitches that feature this same double-shear design.
