So there's not much out there for lifting Denali's so I figured I'd throw a How-To out there to help out all my AWD Autoride buddies.

First off this kit was from Summit Machining on eBay. It was on sale for $90 for 2.5'' front and 1.5'' rear. The front offers an upper and lower spacer, instead of one giant spacer up top. I like how it adds a little on both sides, in a way that keeps the strut centered.

My truck does not have any weird vibrations, my autoride still functions perfectly normal, and the truck rides just like stock. So if any of these are deterring you from lifting your vehicle, have no fear she'll be fine. The one thing you will have to deal with is the occasional "Service Suspension System" light. I'm still not sure what causes this, but I am looking into a fix for that.

So let's get down to business! First, lets talk front end disassembly.

1. Jack up truck, put jack stands on front subframe.
2. Remove wheels.
3. Take a socket and wrench and remove the swaybar end links.
4. Take a 10mm socket and remove the brake line/wheel sensor bracket off the upper control arm.
5. Pull the plastic clips out of their slots for the wheel sensor to give it some slack when raising and lowering the spindle assembly.
6. Take a wrench and pull off the tie rod.
7. Take an 18mm wrench and loosen the upper ball joint, but do not remove the nut so the whole assembly does not fall.
8. Smack the upper ball joint with a BFH lol
9. with the lower control arm supported, remove the ball joint nut.
10. Pull the three upper nuts and two bottom bolts off the strut.
11. Remove strut and prep for spacer install.

So now that the strut is out take the 3 ( nuts and use them as a guide to trim the studs on the strut, so they do not protrude from the recesses on the new upper spacer. A grinder works great here. Also, be sure to get the orientation of the upper spacer to the body correct and mark it with a sharpie. This will keep you from having to guess which way the strut goes in.

Reassembly is the same just backwards. One word of caution, place the lower spacer on the lower control arm before the strut goes in, it is easier then trying to wedge it in between the strut and its bottom mount.

Also, when raising and lowering the control arms make sure you don't lower it too much, you don't wanna be pulling or ripping out your brake lines (See step 4 ;) )

This is a pretty straight forward install. The new nuts will go on the top mount under the hood, and the old nuts will be used to attach the spacer to the strut in the machined recess.

Back end:
1. Jack up truck on pumpkin
2. Place jack stands under the frame.
3. Pull of wheels.
4. Unbolt the lower shock mount.
5. Unbolt sway bar.
6. Pull the electrical line clips out of the frame for slack.
7. Disconnect the brake line brackets near the shocks and near the pumpkin. These are some solid lines and you don't wanna pull on these.
8. Now that everything is disconnected lower the jack slowly until there is no pressure on the springs. Watch your brake lines.
9. When there is no pressure on the springs pull them out. Put the spacer in the bottom of the spring, and on top of the rubber on the lower mount. Have your buddy stand on the axle/rotor so you can get the taller spring assembly back in there. Repeat on other side, and reassemble.

All in all this took about 2-2.5 hours and was super easy. The lift may sound small but it made a huge difference and I love the way it sits. Not too big but noticeably "stout" compared to stock. Stock size tires look ok, but going up a size or two will make the truck even bigger.

Additionally, I pulled off my front valance to make it look taller, but there is a bunch of holes where it clips in and it looks unfinished so I will be re-installing that piece.

If anyone has any questions feel free to hit me up. I am looking forward to seeing more lifted AWD trucks, and it really rides and performs like stock, so don't hesitate.

Love the mild lifted Denali! I put a 7" lift under mine and love it! The "service suspension light" is due to the ride height sensors being lower. You need to make longer rods for all corners or a spacer like such from Full Throttle Suspension. Hope this helps others lift Denalis

Thanks man it's kind of uncharted waters and you don't see many so I figured I'd make a write up! How can I extend the links and what angle do they need to be at?

How's your fuel economy with those huge tires and lift? I wanna go up a little more in the future. Only getting 12-12.5mpg right now, but hey didn't buy it for fuel economy lol

I'm not too sure how to extend the front but I know you could order a front set and install on rear but don't know where it will put the switch. I recommend ordering 2 sets (4 spacers) from Full Throttle that allow adjusting with set screws.

Mine gets 12.6-13 all city driving right now. Need to see what I get on the highway. I have a tune and intake. Trying to get it back up to 14 average with summer gas.

Jeeze....i would love to get that mileage and I'm only 3'' higher than stock with stock tires. Im averaging 12.5 right now.

I will check out FTS website.

I put the 2" rancho quicklift loaded on 2 days ago, and I already want to take it off. I like the look and it has a slight Cali lean. It did come with an autoride over ride feature so I'm not getting any error message, but I don't have autoride. The reason I want to take it off is because it bounces like crazy. Like a car that needs new struts... I have tried every adjustable setting... Still bounces. I have driven a stock 09' Yukon and it doesn't ride like this, so I know it's not normal. I've never ridden in anything this bouncy... It's terrible. Help, suggestions... Anything!

^I no longer have front autoride. The rear autoride works fine.

Good job, looks good, I'm wanting to do this soon on my caddy with the same suspension. Does anybody use the differential drop brackets with these?

Return it and order a kit like mine. The quick lift changes how it rides, but mine rides great and is firm but comfortable just like stock. Return the rancho's while you can still get your money.

Pm me with any ?'s

No need for the diff drop with these. However I have considered going taller than 2.5 up to 3.5 and anything over 2.5 needs the diff drop to retain better quality CV angles.
