Extended Travel Ball joint style Nitro Gear Upper Control Arms (Pair)

The short-comings of OEM 100 Series IFS: In 1998 Toyota released the all new 100 series Land Cruiser to replace its solid axle 80 series models. While providing a much smoother ride and better handling on the road, the IFS proved to be very limited in suspension travel. Most lift kits for the IFS setup simply raise the front end by means of adjusting/replacing the torsion bars which actually reduces overall down-travel. This is the result of aftermarket suspension kits only utilizing stock length shocks. Driving over rough roads and potholes compounds this problem as the pre-loaded suspension, with fully extend shocks, has no more room for shock travel resulting in poor ride quality and premature shock failure. The only way to improve suspension travel is to run longer than stock shocks. The factory upper control arms also become a limiter as they will contact the shock body if using longer shocks. With a raised suspension height, the OEM upper ball-joint is forced to operate at an extreme angle and wider tires many times will not clear the factory upper control arms. The OEM ball-joint also has a potential to separate if a stock length shock were to break, leading to catastrophic failure of suspension, steering, and CV axle.

The Solution:

  • To solve the extreme ball joint angle of the stock arms the ball-joint cup is clocked to run level on vehicles with 2-3" additional ride height.
  • With the proper shock setup, this allows up to 50% increase in down travel over OE/Aftermarket suspension kits that use OE length shocks. (we offer these)

This listing is for the Upper Control Arms only.

If you already have aftermarket suspension, and looking to upgrade we also offer the extended length shocks needed to utilize the full increase in travel that these UCA's allow.

Shock tips:

To utilize the full benefit of these UCAs, see the recommended Icon Vehicle Dynamics extended travel shock, as we worked directly with Icon to develop the proper specs to maximize travel and optimal dampening. (yes we've tried all the others)

Tech Note:

We also recommend using a diff drop kit DIFFDROP-TLC100. Installation should be done by professionals with suspension experience. Suspension should be cycled prior to driving to avoid over-extension of steering components, cv"s etc.
