I didn't want to hijack RustTBSS thread, so I'm starting my own.
I did the rear 30.5 coil conversion, with the adjustable SPohn Pan Hard bar, Upper and lower control arms as well. With Tony's belltech shocks and the DJM rear sway bar.
I either have bad shocks or I did something wrong, because when I go over really big bumps, it feels like the entire rear is about to rip out of teh vehicle. It feels like the shocks are too short and are hitting the end of their travel and the weight of the entire rear is slamming the shocks at the end of their travel. Does this explanation make any sense? BizzzzNYC has been trying to help me, but something just doesn't seem right. what am I missing?
:dunno:

Well, that was apparently NOT my issue, since I cut them down, and I'm still getting the same problem.
It feels like I'm riding on all springs, with no dampening from the street performer belltechs. And when I hit a large bump, or pothole? It literally sounds like I'm going to leave the entire rear end on the ground behind me. Argh!!!

Shocks installed upside-down? Sleeved area should towards the top.

It's hard to see, bit this is the driver side shock. Both sides are mounted like this.

Need some flash or light so we can see the whole setup underneath.

1) are you sure exhaust is not hitting the axle over the rear hump?

Did you change the endlinks on the rear sway bar after you lowered the truck to shorter ones? If not, that bar will definitely hit.

Would that bar hitting, make it feel and sound like there's no damper happening? Like I'm riding on nothing but springs? I did not do the sway bar links yet, but I do have the ones from the group buy, to install with the djm sway bar. Tomorrow morning for sure.

If you were riding on just springs you'd be bouncing down the road. Being that low you'd bottom out constantly. Are the shock bolts really tight? Triple check everything.
