Kbuskill's 2008 Burb LTZ "MOD" Thread

Only idiots experiment with their suspension.

[emoji1787] I got that one dub!

Are you leaving the coil spring and adding helper bags or just running the airbags? If you're leaving the coils, you should be fine. If not, it will have an exaggerated amount of body roll.

I haven't followed the whole process, I just recall seeing bags...

Just the TBSS bags, or air springs as GM calls them.

I already have 6" drop springs and Helper bags along with air shocks.

I am not sure how the compressor and relief valve works but maybe a simple system with two check valves in the pressure lines and a pair of relief valves independent of each other would work. I dunno how the pump is assembled.

Dump valve is built into the auto leveling compressor so if I put a check valve in line with each bag the rear would never dump once it lifted.

To put a relief/dump valve on each bag would make it manual dump and defeat the "auto" in auto leveling... lol

Who knows, you all may be (probably are) right and I may hate it and I may have to figure something else out, but I don't drive the truck like a race car so it may be fine for what I need.

Time will tell.

So the Moog rear upper control arms arrived yesterday.

They too are supposed to be RK series.

The box says RK series but the bag has this part number on it...



Kinda weird.

Kinda weird.

I thought the only difference between the RK and the CK was the warranty?

New Moog CK series upper and lower control arms, outer tie rod ends and SKF X-tracker Hybrid wheel hubs installed and the new polyurethane bushing upgrade kit installed on the steering rack.

Noticed a leak on one of the power steering lines so they will all get replaced.

New 305/40/22 Michelin tires and front end alignment done.

261,361 miles.

305 tires rub the wheel well liners slightly under certain conditions. Will have to massage the liners a little more.

My 14 yr old son is becoming quite the mechanic with my supervision since I am not able to do as much as I used to.

How did that bushing install go?

I'm not sure, everything I read said that the RK was their economy line and CK was their Premium line.

I know the CK series is their "Problem Solver" series for whatever that is worth. They market the problem solver stuff as being an improved design over stock.

You are correct though, the RK series has a 36 month warranty while the CK is lifetime.

Short Answer: R Series is a value-driven replacement part while the CK Series incorporates Moog’s premium Problem Solver components for a better than OE upgrade.

Are you talking about the poly bushing for the rack?

If so, it was a real pain to get the bushing back onto the rack once it was inside the bracket.
