Should have been screwed together like that before it rolled out of Fort Wayne.

What's the part number for the Bilsteins and how much did they cost ?

Any fitment issues on the right hand side around the exhaust pipe? I have a 6.2 EC

Wonder if that'll clear the 14 bolt diff, or if I put a diff girdle on later.

Can’t speak definitively to 6.2 fitment as mine’s a 5.3 EC.
It’s difficult to tell from this lousy lunchtime picture, but the vertical link is rearward of the hanger by ~3/4” and clears the pipe fore-aft by at least 2” at its closest point.

Looks to be plenty of clearance for aftermarket differential covers. Alternatively, the bar-to-axle housing mounts can be rotated rearward to gain extra space.
Picture is with them almost exactly level (parallel) with the garage floor.

In the spirit of full disclosure…some minor trimming of the upper LH shock mount is required for saddle bracket clearance on our NNBS.
Nothing 5 minutes with an angle grinder and some Rustoleum couldn’t handle.

On the 6.2 trucks there is a resonator right where the exhaust gets close to the link.

Whoops! Of course I’ve seen many a 6.2 Silverado and Sierra with a resonator in that exact spot.
Since it’s never my intent to post faulty intel, I regret the omission.

Telling GM saw fit to install a substantial rear bar on most every Tahoe, Yukon, Escalade and Avalanche it builds.
Coil suspension to be sure, but the improvement in directional stability and crosswind resistance increased rear roll stiffness provides is undeniable.

My previous ’92 Sierra had a Hellwig bar that mounted above -and in front of- the differential with its arms extending forward, similar to this NBS article in GMHTP:
2004 Chevy Silverado - Modified Truck, Custom Truck - GM High-Tech Performance Magazine

Addco may make a GMT900 rear bar with similar mounting configuration:

Ill take a few pictures of my exhaust and post them up. Hopefully you can tell from them if they will clear the 6.2 exhaust or not. Sway bars is pretty high up on the list for me to do.
