1998-2007 Land Cruiser 100 Series


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.

riving 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. Also, The OEM upper Ball joint is not sold separately so you must buy the whole arms, which cost more than the pair of our heavy duty extended travel Ball-joint type arms available here. As an added benefit our arms accept the the Tundra type ball joint (as they are more common), they can be replaced with joints available at nearly any auto part store.

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)
- The arms are 100% BOLT-ON and fit in the stock tapered ball-joint location in spindle. That's right no drilling, no welding, no tapping. Arms allow for proper alignment.
- They are also fully serviceable, as the bushings and ball-joints can easily be replaced. The ball joints and upper bushings include zerk fittings for quiet squeak-free operation.
- Made in USA, TIG Welded, Chromoly DOM tubing for strength versus the flimsy OEM stamped steel arms.
- This design allows for a lower profile, thus providing additional clearance for larger tires, and/or larger/ longer shocks.

- The arms utilize a sealed 2007 Tundra type upper ball joint, making them serviceable at regular auto part stores.

This is for the UCA's Only. To Build and Purchase a Complete Suspension kit Click Here. or email info@justdifferentials.ru for more info. 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 UCA’s see the recommended Icon Vehicle Dynamics extended travel shock, as we worked directly with Icon to develop the proper Specs.

ICON2.5LC100-F Icon Extended Travel Front 2.5” Internal Reservoir Shock

ICON2.5LC100-EXT Icon Extended Travel Front 2.5” Remote Reservoir Shock

ICON2.5LC100-CDC Icon Extended Travel Front 2.5” Remote Reservoir Shock w/ CDC Adjusters

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