Lowered 1988 Chevy CK1500

[Scotts1988chevy]

I have a 1988 Chevy CK1500 and had it Lowered 5x7 it's bottoming out it has a c- notch plenty of room between axle and c-notch I'm using Belltech street performance lowering shocks and coil Springs. I'm thinking of going to use coil overs in the front maybe adjust a shocks in the rear end anybody have any ideas ?

Thanks

Have someone jump on the back bumper while u look under it. Shocks might be bottoming out before it hits the frame. Or it hits the inner fenders in the front, etc. hard to give more info without tire size but usually if it bottoms out it’s either shocks, inner fenders or the frame.

Yeah.. need a whole lot more info. Tire size would help. They almost look like OEM size 235/75/15, too tall for a 5/7 drop, especially with stock type wheels.

The C-notch could be installed incorrectly. I've seen them be mounted just a little bit too far off and the rear axle bump stop pads will smack the edge of the notch.

A lot of different things could be described as "bottoming out" so what and where is actually hitting will go a long way towards suggestions on a remedy.

Without the above mentioned information, my guess is that the pumpkin is hitting the bed.

If the brace under the bed is not notched above the differential, they could be making contact. Especially with a 7" drop.

Cross member notch. A must for a 6" drop, let alone a 7".

and an excellent example of a well-done crossmember notch.

It's strange. Not one of the flip kit Co.s mention anything about the box cross member needing that notch in any of their instructions.

I kinda thought Belltech did.. or used to? Maybe I imagined it. Last GMT400 I notched was.. uh.. in 2007. Had to look it up.
