How to: Install of Eibach Pro kit (non auto ride)

This install took me about 3.5 hours and was somewhat involved. A friend to help is a must to make it go smoothly. Here's what you need to do it:

1. Hydraulic jack, stands, and wheel chocks
2. Air compressor (optional, but it will go 2X faster)
3. Spring compressor (You can get at any auto parts store)
4. 21mm deep socket
5. 18mm deep socket
6. 15mm deep socket
7. Pry bar or something for leverage

I opted to do the rear first so you will need to chock the front wheels and loosen the lug nuts slightly on the rear wheels.



Next, position the jack under the rear differential and jack the truck up until the rear wheels are off the ground a couple of inches. Place the jack stands under the frame rails, then drop the weight of the truck onto them, making sure they are level and secure.



Now, remove the rear wheels and use the 18mm socket to loosen the sway bar nuts as shown



Now, remove the shock bolts using the 21mm socket



Once the sway bar connections and shocks are disconnected, very slowly drop the rear end down, careful not to snag any sensor wires or brake lines.
As the rear end comes down, the springs will loosen and free up. Go ahead and pull the springs out. It might take a little bit of gentle persuasion.

Notice the difference between the stock and the new Eibachs:



Take the rubber off of the stock springs and put on the new ones. The rubber prevents any noise from the spring coils touching.



Reinstall everything in reverse. Have a buddy jack the rear up as you guide the springs back into position. Re-tighten everything up and that's it for the rear.

Now the fun part! The front!

Use the e-brake to keep the back from moving and use the engine crossmember as a jacking point. Position the stands like before on the frame rails and remove the front wheels. The front uses coil over shocks and provides a pretty supple ride.

Start by removing the two 15mm bolts on each side that hold the bottom of the coil over assembly to the lower control arm.



Now, locate and remove the 3- 18mm nuts on each coil over holding it from the top. You can do it from underneath or on top. (I did both) The top will require the use of some extensions to reach.

Now once all the nuts/bolts are removed, use the pry bar to remove the assembly from the bottom.



Here's the assembly next to another important tool...



Now, loosen the 18mm nut on each top hat of the coil over SLIGHTLY. Do not take it off, you will be SERIOUSLY INJURED by the spring. Use the spring compressor to take the tension off the spring. Once the tension is off, remove the 18mm nut and pull the top hat and spring off the shock.



You need to replace the stock bump stop with the supplied bump stop or cut 2" off of the stock one. This will allow for use of the stock shock and make for a factory ride.

Be sure to do one side at a time to allow a stock reference to the order of the dust boot, spring top and bottom, bump stop, etc. Reinstall everything in reverse and tighten up all nuts and bolts. Drop the truck down and admire your new stance!!

Here's the before and after. Not a huge difference, but better! Happy slammin!!

Nice!!

Great write up and step by step pics. Thanks. Tahoe looks awesome.

How does it ride compared to factory? What size tires do you have and the offset of the wheels, and does it rub any?

It rides nice and handles great. There is less suspension travel so it doesn't feel like you are floating on a cloud anymore. As with any lowered vehicle, you trade off a little comfort for performance. To each his own!

As for the size, they are 275 55 r20's and IIRC, the offset is +40. I have had no rubbing issues whatsoever.

lift, not drop

Nice write up. Pretty straight forward. However, I'm looking for about a 2-3" lift. Any suggestions w\out messing up the ride or gas mileage?

Eibach w/ autoride

I installed a set of Eibach springs on my 07 w/ autoride this weekend. The front dropped 2-3/4" and the rear 2-1/2". The install went very well. Eibach includes shorter push rods for the autoride sensors. The ride is great but the front is so low I can't roll a floor jack under. The truck still has the stock looking rake. I was looking for a level look as well. I ordered 2" spacers for the front to level the truck. I hope I can cut them down to 1-1/2". I think this will give the truck a good "SS" look.

i like it. looks like it leveled it a tad as well.

did you need an alignment right after the spring swap? i wouldnt think so since you didnt have to pull the spinles or anything.


SlickTahoe - that sucks that your kit made your rake worse! doesnt eibach advertise more drop in the rear on those springs???? i want my tahoe to be level.

I added a 2" leveling kit from Super Lift in the front. Now it looks perfect. I have about 1/2" of rake and the truck corners like it's on rails.

You should always get the alignment checked when you do anything that changes the attitude of the vehicle.

im talkin about getting it to the shop. when i did the drop on my S-10 with spindles & springs in the front, i was lucky i didnt wear my tires out driving 15mph for 2 miles. i had to do a cave man alignment at home to drive it to the shop.

with the coil over set-up on the tahoes it should only be a slight adjustment needed. im excited about it now. i wasnt going to touch my tahoe suspension untill i saw this thread!

hey man, i just noticed something. i can see the numbers writen on your spring box and it says 38106.540.

according to the eibach website, the PN for the non-autoride vehicles is 38107.540, and the PN for the autoride tahoes is 38106.540.

looks like you might have the springs for the autoride vehicle on your tahoe.

just thougth id let you know....

Thanks, I have a LTZ w/auto-ride

my previous post was meant for GAPP. but obviously the springs for the autoride trucks fit the non-autorides....

post some pics slicktahoe.

the kit for the none a/r comes only with 4 springs?
