  • Easy 3 bolt installation per side
  • Constructed from laser cut 3/16" steel, with 3 layers of added internal gusseting.
  • Turning clearance maintained with 37x12.5 tires on factory +57mm offset wheels with zero rub at full steering lock*
  • Turning clearance maintained with 40x13.5 tires on +18mm offset wheels with zero rub   at full steering lock*
  • Uses proven OEM rubber rear pivot bushings
  • Multiple hole mounting positions for limiting-straps, if needed
  • Maintains factory OEM alignment and axle placement geometry, so they function great from 0-3.5" of lift
  • Does fit the 2014-2023 Power Wagon, but be sure to read the below notes.

*You will need the Thuren High Clearance Sway Bar, and you must replace/modify/trim your fender and liner/rocker seam, to take full advantage of a larger tire size and new turning radius ability.

Power Wagon fitment details: This arm fits the Power Wagon perfectly, but you will loose some articulation with the Swaybar disconnected. You will gain some better road manners with our arm, and gain similar turning radius advantages, but only if your OEM Radius Arms are the first point of tire contact. The second point of contact will still be the OEM swaybar, so the turning radius gains will not be identical to the 2500/3500 regardless, so long as the OEM swaybar is retained. Naturally, our arm is much stronger than the OEM Power Wagon radius arm.

    Shipped fast. Very well built products. Also installed the sway bar and the front end is now solid.

    Excellent service

    Ram 2500 2022. Radius arm. 56 pounds each. It wasn’t easy to ship to Puerto Rico
    But they got it (they went the extra mile)

    2020 Dodge Ram 2500 Alien Radius Arms?

    Twice as heavy as stock clears nitto 37x12.5 all day on stock rims. I drive a lot of gravel and didn’t want offset rims sticking out beating rocks off the side of my truck.

    Massive ! Your fed ex guy will hate you !

    These things are amazing ! They are beefy and look great. They look so much better than the stock ones. The front in on my 2018 2500 feels solid and no rub from my 37s. Love them !
