MX83 Front Lower Control Arms

  Our innovative new front control arm design uses two easily replaceable/adjustable heims and massive taper adapter along with a proprietary tension rod to give you a big range of adjustment from stock track width to +2" (50mm) per side.

   With our unique design using two heims and a dual position tensions rod, you can maximize wheel clearance to the tension rod and chassis while keeping the tension rod axis of rotation in a reasonable range helping with alignment and Caster. If you’ve ever tried to do cut and welded stock lower arms, you know how bad it gets when the tension rod get off axis.

  We’ve also included new heim sway bar end links and incorporated steering stops. On our test car we were able to get just over 8 degrees of Camber at full arm extension with coil overs and camber plates.

  If you think 2” per side isn’t enough track width, just give us a call. With all fabrication of the components done in house, we can make custom arms in any width you want.

  Due to the combinations of steering arms, track width, steering rack and inner tie rods, you will need determine how to appropriately modify your outer tie rod ends/steering. We have a few choices of options to help solve the problem. Our standard version Heim tie rods typically work up to +1.25" track width. The long version Heim Tie rods will work for +.75" to +2". Both are figured with MX83 factory inner tie rods. For specific combinations, please contact us with your details via send us email.

 While these arms are built to handle abuse, they are designed for intermitent track use. Daily driving is typically more abusive then track time due to the constant repetative shock, exposure to prolonged vibration and road grit and debris. Yes, public roads can be worse then track time. Solid components such as heims and taper adapters do NOT absorb any of the constant vibration associated with daily driven road miles and can cause component failure and expedited wear. There's a reason factory parts for road use are fully sealed, greased and mounted on rubber.
