The Slee lift kits were designed to give you the ultimate in off-road ability yet retain great street manners. Offered as a direct bolt on or DIY kit.
These kits consist of all the parts necessary and recommended to lift the 80 Series correctly while addresses all of the drive line and steering geometry changes when going to a 4" or 6" lift. Using proper spring rates and adjustable rods and arms, together with caster correction methods that does not require drop brackets, you achieve the maximum under carriage clearance without sacrificing driveability.

The 6" lift kit was develop as the ultimate off-road kit available for the 80 Series Land Cruiser. This kit approaches the maximum possible lift for a 80 Series Land Cruiser before one enters the world of custom fabrication and redoing the link system due to excessive angles and possible damage/binding when articulating. Although the truck is still 100% drivable and has handling, this is the kit that we recommend for the people that want to run 35" or larger tires and want to play hard.
The Slee 6" coil springs are a heavy spring rate to accommodate most accessories commonly fitted to off-road trucks. The SOF5FM and SOF5RM Medium Load springs are set up to handle 250 lbs in the front and 400 lbs in the rear and still yield a 6" lift. For extra heavy applications the SOF5RH Rear springs can be installed.
The stiffer spring rate were chosen for minimal body roll on-road, yet still retain good articulation off-road. This offers a much improved ride over using a softer spring with spacers to achieve the same lift height.
Caster is addressed by custom Slee front control arms that machined as a single piece from 1.75" plate. The arms are ready for installation with Toyota OE bushings installed. The arms correct both caster and the positioning of the front axle.
Panhard rods (sometimes called lateral rods or track bars) are supplied with custom machined adjustable joints ensuring that the axle tracking can be dialed in 100% for each vehicle, no matter the lift height.
Vibrations are addressed by a double cardan front drive shaft to ensure smooth operation. The rear drive line angles are adjustable by using the rear adjustable upper control arms. In most cases the pinion can be rotated down to correct the rear drive line angle changes. In rare occasions, this is not possible and a rear double cardan shaft must be installed to ensure smooth drive line operation.
To prevent over stretching of the brake lines, a set of direct replacement Slee DOT approved lines are supplied. These lines come complete with clips, and feature a sheath covered woven steel braid. The lines are 4" longer than stock length.
The necessary drop brackets and spacers are supplied to return sway bar close to stock positions. Bump stop drop blocks are supplied to ensure that the supplied OME Nitrocharger Sport Series Shocks are not over compressed and damaged. The kit is supplied with longer direct bolt in OME shocks to ensure proper articulation. Slee Shocks can be substituted for additional performance.
The 4" lift kit was put together for people that want to run up to a 35" tire, have good handling yet still use the vehicle on a daily basis for commuting or long overland trips. The spring rates were chosen to give a stable on-road ride, even for heavily loaded trucks.
As with the 6" kit, the spring rates of the SOF4FM and SOF4RM springs are chosen for 250lbs additional weight on the front and 400 lbs in the rear.
This kit contains all of the same parts as the SOF 6" Kit, except the springs yield 4" lift.
Instead of the front control arms, this kit corrects the caster with the Slee Caster Plates. These plates provide caster correction by using the stock front control arms but rotating the mounting points. Minimal cutting is required to fit the plates and a small amount of welding is recommended on the fitment.
Its recommended the adjusters be TIG welded into the arms to ensure proper weld joints.
This kit will allow for fitment of a true 35" tire. For larger tires trimming or additional bump stops are required since the wheel wells aren't large enough.
Tire size suggestions are made assuming stock wheels. However, with a 6" lift we suggest that the width of the stance is increased. This can be done by using wheel spacers or different offset wheel.
This kit will allow for up to a 35" tire. If larger tires are desired, we recommend going to the 6" lift.
