NORCAL SS Kit info/tech on how to level the rear of a 2015 up GM SUV

[CMoore711]

Anyone else using the 1" spacer and stock sway bar have any extra sound from the rear when going over bumps?

Same rear set up on my ‘15 Yukon XL Denali and no odd rear end noises here.

Only thing I can think of is when I placed the top rubber mount on it wasnt in the exact same groove as the stock spring was but figured the rubber would settle and conform to the new spring. Maybe when the second ring pushes up and makes contact with the rubber I hear a rubber squeak? IDK

Just dont like rolling through the neighborhood making noise like that....makes me feel cheap

So I’ve got the springs and spacers installed, but my question is in regards to the links. From what I’ve gathered, 3-11/16” is the distance from the shoulder to the other shoulder of the end links. But the new rods are about the same length as factory. So what’s the rough length to start with and how do I take the end links off the factory rod? They just spin and spin so they aren’t threaded, I assume. Thanks

 

[Dearmosd]

They shouldn't be same length. You will have to pull the end caps off. Yes they spin but will pop off. The new rods should be about 1/4 shorted easy. From center cup to cup should be about 3" with new rod. I ended up a little shorter when using the plastic 2" spacer instead of the factory rubber piece.

So I just got my kit in the mail for my ‘16 Yukon. I want the rear lowered ~3” in the rear.

If I install the isolators on the axle and the supplied springs and links, how much will this drop the truck?

Being a dealer for Belltech/DJM/Mcgauhys/Eibach/Matrix I tested them all on the 15 ups and tested which one works best and the 5305 belltech springs by far are the winnners. This customer came to me today so I just wanted to show how simple it is to lower the rear. Hearing shops charging 2 hours to do this is a rip off. NOTE THIS IS FOR A AUTORIDE TRUCK INSTALL

KIT FOR AUTORIDE IS 250 SHIPPED AND 1.75- 4 ADJUSTABLE

KIT FOR NON AUTORIDE IS 275 SHIPPED and adjsutable 2-3 inches


Lets get onto the install.

1) Jack truck up and put jackstands on both sides in front of lower a arm frame brackets

2) Next pop open the clip that holds the abs lines on the frame and make sure they hang freely

3) Pull out oem bumpstop and instert new shorter bumpstop

4) AUTORIDE ONLY --- Next pop off autoride links on upper a arms and replace with the rod that is included with my kit. Due to different spring rates on the front of the these trucks my rods are longer so you can adjust the rear not to sit lower than the front.

5) Place a floor jack under the rear end and pump it up just enough to release tenstion on the shocks

6) Remove the brake line bracket on diff. If you do not do this when you go to release rear end it will snap the brake line

7) Remove shock from oem bracket and install shock extenders but do not bolt shock back yet
View attachment 169633

8) Unloosen endlinks on both sides and remove from bar. I usually put the bolts on ends to keep work area cleaner

9) Now SLOWLY release floor jack to let rear end down. Making sure the ABS lines and the brake line bracket on the axle are free to move around

10) The spring you will be able to pull right out. Then you put the new springs in WITH CLOSER COILS FACING UPWARDS and the 1 inch spacer goes on the axle

11) The top coil will have a insulator and this pic shows whats under the insulator. MAKE SURE THE INSULATOR SITS CORRECTLY ON THIS LIP AND THE INSIDE OF THE TOP COIL SHOULD WRAP THE OUTSIDE OF THIS LIP. I usually jack up the rear end while guiding it in

12) Once you jack up rear end tighten shocks to shock extenders

13) Pop on the abs lines back into the frame clip

14) Bolt the brake bracket to the top of the rear end

15) Put tires back onto truck drop it down and drive around the block. On my kit I will update all info on how to dial in ride height in rear.

Tony I noticed your website has the lowering kit supplied with Belltech 5305 coils. My kit came with 5301 coil. What would be the difference?
