2017.5 and newer Polaris RZR XP 1000 and RZR XP Turbo owners run the 12mm Bolt rear radius rods, and the factory arms flex and bend before anything else back there does. This LM UTV 64-inch kit replaces them with Billet high clearance radius rods in 6061 Aircraft grade aluminum, lifting the lower arms clear of rocks and ruts and running F1 Fitment on all bearings.
The lower arms are fixed length so the high clearance geometry holds, and the uppers are adjustable, which is what lets rear toe be set with the arms still bolted to the car. LM UTV lists it as a Direct Bolt-on Replacement, and this kit does fit with the OEM rear bumper.

Built To Solve: Flexing And Low-Hanging Rear Radius Rods On The 2017.5+ 12mm Bolt Polaris RZR
- Lower arms hanging in the strike zone. The factory lower is the first thing to meet a rock or the edge of a rut, and high clearance geometry moves it up out of the way.
- Rods that flex under load and stay bent after. A deformed arm holds the wrong rear geometry from that point on.
- Rear toe that walks after an impact. The car hunts under throttle and eats the inside edge of the rear tires.
- Sloppy, loose-feeling rod ends. The 3 Piece Chromolly PTFE lined 5/8 bearings run F1 Fitment on all bearings rather than a loose press.
- Lower arms twisting in the mount. The 17-4 Stainless Steel spacers designed to keep the lower arm upright hold the arm square.
- Giving up the rear bumper for clearance. This kit does fit with the OEM rear bumper.
Best For: 12mm Bolt Polaris RZR XP 1000 And XP Turbo Owners On The 64" Chassis
- 2017.5 and newer RZR XP 1000 and RZR XP 4 1000 owners on the 64-inch chassis
- 2017-2018 RZR XP Turbo and RZR XP 4 Turbo owners, 2 or 4 seat
- Riders in rocks, ruts and technical terrain who keep catching the lower rear arm
- Owners replacing a bent factory rod who want to upgrade the geometry at the same time
- If your car takes 10mm Bolt hardware at the radius rod mount — 2014-2016 RZR 1000 and 2016 RZR Turbo — order the 10mm Bolt kit instead; these two part numbers do not cross over
- Polaris RZR Turbo S owners are on the 72-inch chassis, and Pro XP owners need the Pro XP kit; neither is served by this 64" part number

Fitment
Fits 2017.5 and newer Polaris RZR XP 1000 and RZR XP 4 1000 through the current model year, and 2017-2018 Polaris RZR XP Turbo and RZR XP 4 Turbo, in 2 seat and 4 seat form on the 64-inch chassis. LM UTV states the fitment as: Fits 2017 .5+ RZR 1000, 2017-2018 RZR Turbo. 2/4 Seat. 12mm Bolt. The split is by bolt size, not just by year — 2017 is a transition year, so confirm you have 12mm Bolt hardware at the radius rod mount before ordering. Fitment is not guaranteed on applications not listed here.
FAQ
Why do the factory rear radius rods flex on a 2017.5+ Polaris RZR XP 1000?
The stock arm is the soft point in the rear suspension, so it absorbs deflection that the rest of the car will not. Once it takes a set, it holds the wrong rear geometry permanently. This kit replaces the arms with Billet high clearance radius rods in 6061 Aircraft grade aluminum.
My rear rod ends have gone loose and clunky — does this kit address that?
Yes. The kit runs 3 Piece Chromolly PTFE lined 5/8 bearings with F1 Fitment on all bearings, and 17-4 Stainless Steel spacers designed to keep the lower arm upright, so the joint is held to a specified fit rather than a loose one.
How do I know whether my Polaris RZR is a 10mm or 12mm Bolt car?
Look at the bolt through the radius rod mount. 2014-2016 RZR 1000 and 2016 RZR Turbo use 10mm hardware and take the other LM UTV kit. This part number is for 2017 .5+ RZR 1000 and 2017-2018 RZR Turbo, which use 12mm Bolt hardware. 2017 is the transition year, so measure rather than assume.
What exactly comes in the kit?
Kit includes 2 Fixed length high clearance lower arms with 5/8 spherical bearings and 2 Adjustable upper rods with RH/LH 5/8 Heims, using 3 Piece Chromolly PTFE lined 5/8 bearings in 6061 Aircraft grade aluminum. Finish is available in machined finished or Type 3 Hard Black Powder Coat.
Is any fabrication needed to install these, and does the rear bumper stay?
No fabrication. LM UTV lists it as a Direct Bolt-on Replacement on the factory mounting points, and this kit does fit with the OEM rear bumper. Plan on a rear alignment afterward, since the upper rods are adjustable.
How does this compare to the Polaris RZR Pro XP radius rods?
The Pro XP kit is a different car and a bigger joint — it uses 3/4 spherical bearings and 3/4 Rod Ends rather than the 5/8 bearings and 5/8 Heims here. This 64" kit is for the 12mm Bolt RZR XP 1000 and RZR XP Turbo; a Pro XP needs its own part number.
Why LM UTV
LM UTV designs and manufactures its parts in-house, in the USA, and backs them with a Lifetime warranty. The company builds around specific OEM failure points on Polaris and Can-Am machines — radius rods, tie rods and ball joints — rather than covering every category thinly. It is also why this kit's spec sheet names the bearing construction, the bearing fitment and the spacer alloy instead of leaving them to the imagination.
Finish Your 12mm Bolt Polaris RZR Rear Radius Rod Setup
Verify the bolt size at the radius rod mount first — 12mm for this kit, 10mm for the 2014-2016 version — and pick your finish, machined finished or Type 3 Hard Black Powder Coat. After the arms are on, book a rear alignment so the adjustable uppers actually get set, and look at what the arms bolt into, since the mount is where load goes next. Matching rear tie rods and spare 5/8 bearings are the companion parts worth having on hand before your next trip.
