GM fullsize AWD Van Info thread

I have Bilstein in front and Gabriel Max Control #77638 on the rear, I like the ride of the Max Control better than the Bilstein for the rear, they seem to be a little better valved for the vans, less “jolt” a nicer ride overall. I can’t speak to the longevity yet, as I only have 1000 miles on them so far. The Max Control is a mono tube shock just like the Bilstein, big plus is, if you shop around you can probably find them for under $50. Steve

I can not comment on the Bilstein for stock ride height as I have the front lifted 2 1/2” and run Bilstein remote reservoir, they will only work with a lift. The Max Control are rated for a stock Express van but can be run up to about 2-2 1/2” lift. Steve

Hello, can anyone offer advice on mounting position of the ball joint on the Cognito UCA (top vs. bottom)? For reference, I have:
Suburban 6-leaf springs on the rear
Bilstein 24-186643 on the front
Bilstein 24-185615 on the rear
Maxx SMX-MC2 (probably at A4 but maybe at B3?)
Cognito 110-90289
I remember seeing one post with this but cannot find it for the life of me. Normal driving conditions include a lot of weight in the back with kids and gear. Occasional trailer towing. Thanks!

I did get an update for Cognito customer service - they said to mount on the bottom for my situation. But if anyone has input I'd appreciate it.
