Took the Suburban to Speed and Truck World here in
Fort Lauderdale to get the suspension parts installed that @07Burb had compiled and sent with the truck.

They installed the following parts:

- Belltech coilovers Part no. 5403-001 621
- McGaughy’s rear springs (Part no. 0307) with shock extenders
Kit 30014
- wired in the resistors to keep the rear auto ride 100% functional.

Being the wife’s daily driver, we could not get too aggressive with the lowered stance aka slammed and zero fender gap like my NBS was, so this is a “mild” drop to reduce that fender gap a bit.

I can see the difference in the rear and it shouldn’t spark any alarm with the wife. We did close the rear gap by about 2 inches.

Before drop measurements:
Front 35.5
Rear 37

After drop measurements:
Front 35
Rear 35

My NBS was sitting right around 32.5/33” on 24s with a 3/5-6 drop. Big difference.

The auto ride airs up like it should with no error code on the DIC. After driving it around before giving it back to the wife (who hasn’t said anything) it feels more planted in the rear. Not so bouncy. Of course zero rub on 20s. I would love to see it lower, but I’m pretty happy with it thus far. Will see how it rides over the next week. Maybe I’ll adjust the front coilovers down 0.5-1” after the rear springs have a chance to settle in. But, we will see. Still love the long body travel on the roads.

The OEM equipment that came off looked in pretty good shape for almost 9 years old and 68k miles. The shop replaced the rear sway bar end links while they were under there. One was rusted and busted in half before they hit it with a wrench. They threw those parts in at no charge.

- Moog Part Number K700538

Wow I’ve missed a lot these last few months! @Fosscore had no idea you were state side!! Glad you got the burn back! She’s a clean girl and so classy! Love to see the updates!
Hey Chase!! @adventurenali92 Thx mate! I’m back already falling into old habits with the TYF as you can see. Lol

She’s a good old girl and the family is excited to have her back.

Gotta hit you up for your latest detailing tricks and products.

The long body is ready for a DA spin to really make her shine.

Going to be a hot sweaty day to get her dialed in.

Hoping all is well over summer for you.

Those McGaughy's springs ride great, MUCH better than the super squishy Belltech "3/4" springs (which are really a 4/5). I had them in mine briefly but it wasn't as low as the Belltech's (especially since they're 1" lower than advertised).

I’ve still got some driving to do when I can wrangle the keys from the wife.

Initial impressions seem as you mention - more firm and less bounce and even though not as low as I would like , it still knocks out the rake , closes the rear wheel gap with a subtle drop and should not create any wife driving challenges around town while adding some upgraded components to the long body.
