Lowered the truck some more today! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Back in the winter 70GMCer and I lowered my truck using 2.5" drop spindles in the disc brake conversion but it wasn't low enough for me. Today we cut half way between .75 and 1 full coil off a set of stock springs using a 3" air cut off tool. I was suprised to get more drop than I wanted. Normally in the past I have cut 1.25 coils off and got 3" drop. Today we got about 2 3/8" drop (now almost 5" total with spindles). I was hoping for only about 1.75" drop. I'm planning to try to add a set of coil spacers if they are still available. I'd like to bring it up about .75 inch. We also installed new KYB Gas Adjust shocks

Here are some pics taken with my camera phone. I'm real happy with the rake right now with my rear 4" coils. The whole job including cutting the coils took 90 minutes. Thanks again Steve! Here's a few pics. First pic is a BEFORE pic! Second is After shot!.

Looks good to me, don't raise it !!!

Thanks spraybomb!. What I forgot to mention is the drivers side sits lower than the passenger side by about .5" inches when I sit in the truck and wanted to try raising the drivers side only to make it level with the passenger side. 70GMCer had a good idea about we should have swapped springs from one side to the other to compensate for my weight on that side

hindsight is always 20/20

. I'm going to try to find some coil adjusters to raise my side up a tad and then get it aligned. The new shocks make all the difference in the world with this much drop

Can't wait to get new ones for my worn out rear ones too! One other thing to mention is with the aftermarket disc kits it pushes the wheels out further so I would recommend a 7" front rim with a narrower tire. Mine are out a little too far being 8" but I'll live with it.

Advance and other's sale the coil twist lock spacer's that should help you out. They go in between the coil wraps so it want compress that coil.

Andy- I'm going to look for those or the rubber type tomorrow. Hopefully the local parts stores have them in the store.
