1998-2007 Land Cruiser 100 Series Super Deluxe 2.5" Suspension Kit

1998-2007 Land Cruiser 100 Series Super Deluxe 2.5" Suspension Kit

The Toyota Land Cruiser 100 Series has proven to be one of the most versatile platforms of any 4x4. Used worldwide, the vehicle blends on road handling and comfort while retaining much of its off-road capability, ruggedness and durability. Problems arises when you want to lift the vehicle and run larger tires. Most other suspension kits simply offer shocks, torsion bars, and coils and do nothing to address the suspension geometry, cv angles etc. If you plan to lift your vehicle over 1-1.5" the competitors kits present an issue as they offer very little suspension droop, which gives a harsh ride and is hard on your shocks.

Our Upper Control Arms (UCA's) allow you to run the included extended length 2.5" Diameter shocks, for a much better ride, resistance to fading, superior dampening and increased performance as a result of the increased suspension travel. To maintain proper angles we include a powder-coated-bolt-on diff drop kit, premium quality Old Man Emu torsion bars & improved coil springs to match your accessory and cargo carrying needs.

This kit has been installed our very own 1999 100 Series Land Cruiser along with 35” tires, Nitro 4.88 gears, ARB Air Locker and much more. The vehicle is daily driven and sees 20k miles annually. It has been the testing platform for our suspension kit as well as many other products. So far the vehicle has seen 100,000+ miles of all types of driving. From daily errands and highway commuting to rigorous mountain snow and road deicer, thousands of miles of rugged-washboard dirt roads and Moab rock crawling, this truck has done it all. Not only is this the most complete off-road suspension you can buy for your 100 series, it is also one of the smoothest riding and most daily-use-friendly. This setup truly is the best of both worlds.

Tech Info:

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 cost to replace one OEM upper ball-joint from Toyota, is nearly the same cost as the pair of heavy duty Uniball arms available here.

The Solution:

- To solve the extreme ball joint angle of the stock arms the uniball 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 suspension kits that use stock length shocks.
- The arms are 100% BOLT-ON using a taper adapter to 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 uniballs can easily be replaced. The upper bushings include zerk fittings, and each pair recommended DuPont Silicone/Teflon spray lube, 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 1" I.D. Teflon lined uniball which has been proven strong, reliable, and long lasting, for years in all areas of use from Highway, to Baja trucks and more.
