I have a 2006 silverado reg. cab with a belltech drop kit on it. the front has the 2" spindles and the rear has a flip kit. My shackle has 2 adjustments for the leaf springs, on the lower one with 22" rims, my pumpkin would smash the bed and the drive shaft is grinding on the crossmember for the frame. Any suggestions? i am needing to fix this asap. i am putting a set of 18's on to run at the track and dont need this issue.,

 

c notch the cross member then cut your bed out. now you can lay frame if you wanted to haha im JFWY

 

lol i dont wanna cut anything else

 

So you have a flip kit, I assume you have a c notch or else I don't think your diff would be able to hit the bottom of the bed before your axle tubes bottomed out on the frame?? And you have 1"-2" drop shackles in addition to the flip??

This is a lot of drop, assuming your setup is what I think. One of 3 things you can do...

-remove drop shackles, install stock shackles
-install bigger c notch and notch bed frame support where diff is hitting bed
-helper bags or air shocks (going to ride a lot stiffer)

 

your drive shaft shouldnt be hitting the crossmember with only a 6" rear drop. how is your pinion angle? it sounds like you need some shims to bring the nose of the axle housing down so its pointing slightly down towards the ground. that will give you more clearance for the crossmember
