Raising the rear of the Montero

Installing the Valley springs are the best way to improve departure angles and rear articulation. Installing coil springs could not be easier. You will need a few basic hand tools including a pipe wrench, a pair of jack stands, and a pair of jacks. A Highlift jack and the stock unit that comes with the Monty will be sufficient. The best lift point on the back of the Monty is in the middle of the bumper where the hitch pokes out. I recommend cutting that flimsy little strip of metal below the hitch off, since it will get bent trail riding anyway and helps the departure angle. Remove the spare tire and chock the front tires then set the Highlift under the hitch. Lift the Monty with the Highlift until the rear tires barely come off the ground.

Removing the lateral rod

Once the tires clear the ground place a jack stand under the frame on each side of the Monty just forward of the sway bar mount. Place a jack under the pumpkin on the differential then unbolt the lug nuts and take off the rear tires. Take out the right side (passenger) lateral rod bolt and both lower shock mount bolts. Lower the rear end to the limit of the brake line travel. You might have to remove the sway bar mounts which consists of two bolts at the end of the sway bar. I did not have to remove mine. The old springs should fall right out. I was able to squash the new springs in the mounts, but others have needed to use a spring compressor. Make sure you line the end of the coil springs up to the end of the mount. You will see how the coil is made to sit in the mount. This will insure it is fully seated.

The finished product

I had four jacks and used two of them instead of jack stands, but for safety always use jack stands. You can see the sway bar mount in line with the trailing arm just behind the orange Mitsu jack . Notice how tight the brake line is. The brake line on the Monty is in the center of the diff where the least amount of travel is realized unless the whole rear end drops down. Raise the rear end with the jack under the diff until the trailing arm lines up with the hole. I had to use a pipe wrench to twist the trailing arm to get the bolt to go through the mount. The shock mount bolts went in with no problem. Depending on how old your Monty is you might want to replace all the mount bushings with poly bushings while you have them handy. Jack the rear end up and install the rear tires. Use the Highlift to raise the Monty enough to remove the jack stands. Clean up your tools and enjoy the new springs!

Full compression


If you have any questions or problems with the install feel free to give me a ring at the Outdoorwire Mitsubishi forum. These springs are 15% stiffer for a gain of 2.5 inches of rear lift, but are designed to compress fully for maximum articulation. Since they compress fully then they are not made to allow bigger tires, but the Valley springs do handle the 33x1250s BFG MT better than the stock springs.

*Editor's note: This tip applies to all coil sprung models of Montero/ Pajero, Montero Sport and Dodge Raider.
