All Pro Off-Road Coil Spring Spacer

Coil Spacers as Received from All Pro.

The introduction of the 1990 Toyota 4Runner, also known as the Second Generation 4Runner, hosted a handful of changes to both the chassis and body of one of the very first vehicles known as a sport utility. One such change was the departure from a leaf-spring rear suspension to one that utilized coil springs to support the truck and multiple control arms and links to locate the axle. While this system works, it is geared mainly towards ride quality, and lends itself to some compromises for those 4Runner owners who wish to wheel their trucks on more difficult trails. In addition, coil springs can only yield so much in suspension lift before other related componentry (such as the aforementioned control arms and locating links) also need to be changed or modified.

4" Lift Coil Springs.

So, suppose the owner of a coil-sprung 4Runner wishes to achieve more lift for the rear of their 4Runner say, to fit larger tires. What are the options? First, many companies offer lift springs and/or spring and spacer combinations. Taller springs work to an extent, but often at the cost of ride or weight carrying capacity. Spacers work well also, but often times, when combined with a tall lift spring, results in the problems discussed above.

A good combination would be a mild lift spring that has a higher spring rate, and a coil spring spacer designed to increase lift, but not go overboard and stress the other rear suspension parts.

All Pro Off-Road, known for building quality aftermarket off-road parts and accessories, has seen the need, and addressed it with their aluminum 2.5" lift spacers. These spacers allow just enough extra lift and can be used in conjunction with the stock rear springs or 1.5" lift aftermarket units. Follow along on the install and overall impressions we had when we installed the All Pro spacers on our 1992 4Runner V6, which by the way has a Pro Comp Stage II front lift.

After recently installing a set of used 4" lift springs that were way too soft, we ordered a set of All Pro's 2.5" spacers. The spacers are aluminum and come with small metal strips to hold the springs to the spacers.

We chose these spacers because we were very unhappy with the 4" lift springs and wanted to switch back to the feel of the previous rear springs. Initially, the 4Runner was equipped with Downey's 1.5" polyurethane spacers on top of Downey 1.5" lift springs, for a total of 3" of rear lift. The desire to fit 33" tires necessitated at least a 4" lift.

Removal of Coils and Spacer Installation:

Removing Springs with Coil Spring Compressors. Coil Spring Removed. Installing 1.5" Springs with the All Pro Spacers (Note 2x4 to secure axle).

Replacing the rear coil springs on a 4runner is relatively easy. The short step by step is: Secure truck STRONGLY on big jackstands, remove rear tires, disconnect sway bar and shocks from axle, press down on the now free-hanging axle and swap the springs. If you are going from stock height springs to any lift, you will need to replace the rear axle brake line with a longer one.

By jamming a 2x4 between the brake drum and the wheel well, the axle should be low enough to work on the springs. In the case of this install, the 4" springs were already on the truck and needed to be shortened with spring compressors. Stock springs and 1.5" springs can pretty much just be pulled out at this point. Once the springs are removed, and all the mud cleaned (Wonder how that got everywhere!?!), the compressed springs and new 2.5" spacers were pushed into place. The only tricky part of this was getting the springs compressed a couple of inches, as the spring compressors were difficult to work with in this confined area.

Completed Installation. Closeup through Wheel Well.

Once the springs and new spacers were installed, the axle was jacked up a little and the shocks and sway bars reconnected. The entire job took 2 hours from start to finish. Granted, we have removed/installed springs on this truck 3 or 4 times now, and on this go around, an impact wrench was used on the spring compressors.


Spacers Installed under Full Vehicle Weight.

Pros/Cons: Overall we are very happy with these spacers. They fit great, were easy to install, look pretty good, and allowed the use of the current springs. The only problems found were that the metal strips were bare steel with no paint, and were about 1/8" too long causing them to get pinched between the spacers and the springs when compressed. Both of these items are tiny and easily corrected.
