Cool Egan's Mini Lift

This past Memorial Weekend I decided to take advantage of the nice weather and get my suspension goodies installed. The goal was to lift the Sport Luxury Utility Truck (SLUT) by about 2? via Torsion Twist and rear coil spacers.
Parts list:
? Traxda keys
? Traxda 1.5? rear coil spacers
? Bilstein shocks x4
? Cognito UCA?s with replaceable ball joint
? Kryptonite front endlinks
? Traxda shock extenders (ended up not needing these)

I started in the rear since it?s easy. First job is to jack the truck up, put it on jack stands, remove the wheels, and support the diff.



Next I disconnected the top of the swaybar endlink from the frame and completely removed the shocks since I was replacing them anyway.



Then I lowered the diff as far as I could to make room to install the spacers above the coil springs. I had to detach all of the ABS lines from the diff in order to drop it far enough.

Then it was a simple matter of placing the spacer above the coil.



The last thing to do was install the new shocks. For whatever crazy reason, I put the driver?s side shock on upside down. Of course I did not catch this until I finished up for the day and had to spend a quick half hour the next morning flipping it around.

With the wheels back on and everything buttoned up in the rear, I moved to the front. Jack it up, put it on stands, and remove the wheels.



First stop was the torsion bars and keys.



I spent the $120 on the proper tool having learned my lesson over the years that I would pay 10X that amount in frustration and/or damage otherwise. The tool worked great, especially with an air tool to crank it up and down. I placed the tool on the key and cranked it up to take pressure of the nut that holds the key bolt. Once I removed the nut, I uncranked the key, completely unloading it.



At first I struggled with trying to push the torsion bar forward, but all it took was some PB Spray and jiggling the key at the same time I pushed the bar forward to get it out.

Then I installed the replacement keys and cranked them back to their stockish position.

Next I moved on to the front components. Here?s the stock set up:



Removing the stock UCA was a pain because I didn?t have a pickle fork, but I eventually got it out of there. With the UCA out, I then removed the shock and shock mount. I installed the shock mount, then the new shocks. I built the Cognito UCA?s on the ground before installing each in place. Tip: grease up the sides of the UCA bushings because it will be a tight fit!

After a lot of research I discovered I didn?t need the longer shock mounts which is why the shocks look so scrunched up in the pictures. I put the stock ones back on to take advantage of the longer travel shocks. I did have to raise the LCA/hub with the jack to get the shock to line up at full droop.
I also added the beefier front swaybar endlinks while I was at it. When everything was done, I cranked the torsion keys until I got the lift I was looking for.



I had measured the ground to fender lip distances at the center of each wheel before I started. I now compared my new readings to the old (after a short test drive to settle the suspension).



All looks good at about 2? up front and level side to side. I must have recorded the initial left rear incorrectly because there is no way I got 1.7/8? of lift from a 1.1/2? spacer!

Here?s a side by side with the before on the left and after on the right. I still have a slight rake (hard to tell in the pictures due to driveway slope), but a 2? lift in the front.

The rear was probably a couple of hours of work. The first front side I did (including changing both torsion keys) took the better part of 5 hours. I did the other front side in about 3 hours.
Next up is 37? tires!

The front is definitely stiffer and feels like it has more control. The rear feels a little squishier, but that could be the spacer. All in all, I like it.

This is an AWESOME write up! Excellent detail!

I've got the same setup as you and thought that I too still had a slight rake, but the body of the truck itself seems to rake downward as it goes toward the front.

I always take my 'level' measurements at the front and rear of the rock sliders since they're level with the frame; even with them equal I still have about an inch clearance difference at the top of my Gobi...the front being about an 1" lower (6' 8.75" at the front of the front of the rack and 6' 9.5" at the rear).

FYI: I take my roof measurements by laying a level on the rack, letting the end stick out off the side of the truck, then measure from the ground up.

I think I installed this lift just in time. I hit a deer on the way to work this morning and caught him with the bottom left corner of my bumper. 2" higher and he would have hit the plastic "bumper", daytime running light, and my fastrack transponder (bridge tolls). Other than a seriously dented license plate there is no other damage. The deer wasn't so lucky - he was thrown into the median and then rolled into oncoming traffic on the other side.

This was a two lane (in each direction) road. The speed limit is 45 and most people are doing 55-60. I was in the left lane and a guy on a motorcycle was in the right lane and we were side by side when the deer ran out. The motorcycle guy is a lucky SOB because if that deer had come out 1 second earlier he would have hit it. He's also lucky I knew he was there and didn't try to swerve to avoid the deer.

And now I am really glad I didn't drive the BOSS this morning!

Not sure. Traffic is very light when I go into work (6AM). I hit him pretty good, but I was braking and it was a deflecting blow, so he might have got back up.

NICE WORK! Do you mind posting a pic of the suspension loaded instead of drooping? Would like to look at the angles. I have been thinking of a lift but I really like the nice ride of the stock suspension. How does yours ride?

It rides great! I'll have to take some pictures with it loaded.
