There are lots of choices on market for solid axle conversion. So what makes our kits stand out? We feature the highest quality parts, the most complete kit at the best price anywhere.

Our SAS kits include a front diff armor plate, upper axle gusset wheel bearing and knuckle service kits. Items most others charge extra for. To install your solid axle kit your going to need a rear matching lift kit, solid front axle from a Surf or Hi-Lux, and a long spline drive shaft.

We offer our kits in three different heights. The hangers and shackles included with each kit add one inch of lift. Thus our 3" spring kit has 4" lift and our 4" kit would be 5" of lift.

Our rear lift kits are designed to match our front IFS Eliminator kits and classic lift kits. For 4Runners we recommend using a rear kit with springs that are the same size as the front springs.

Kits feature long travel springs and shocks for super flexibility on the trail.

The Classic rear lift kits are supplied for use on 1979-1988 Trucks and for coil to leaf swaps on 90-95 4Runners.

• 56" Long Rear Leaf Springs

Our "Classic" lift kit is designed for factory solid axle trucks and Surfs. Kits include your choice of 3", 4" or 5" springs. Super flexible 47" leaf springs, long travel shocks and high steer crossover steering combine to bring you up to 20 inches of articulation for serious rock crawling ability.

Included with each kit is a knuckle rebuild kit, wheel bearing kits, upper axle gusset and differential armor.

Now our front 5" springs are available in a heavy duty version with a 25% higher spring rate. We have added a 7th leaf and readjusted the length of the leaves to match. If you are running a larger v6 or v8 motor you will appreciate the extra weight carrying capacity of these springs. These new springs can be supplied with your kit at no additional charge. Just ask when you order. If you order online, just put in the notes section that you wish to receive the 5" Heavy Duty option.
