Hunter's 1978 GMC Build
So, Blue was sitting a little low. Some may say lower is better, but Blue was TOO low.. and riding like crap with the mcgaughy's drop coils and the big block. We found out why pretty quick.
I was now riding on the bumpstops and my control arms were banging on driveways and curbs. We did some research, and we decided to go with the MOOG 454 springs for a big block truck. I don't quite recall the part # but it does have 454 in it. We swapped out the drop coils for the stock big block coils. IT LIFTED ME UP LIKE 6 INCHES IN THE FRONT. Soooo... we took it back apart and cut off a coil. Truck sat exactly where I wanted it to, so my setup is now 2.5" drop spindles and a stock big block spring with 1 coil cut.
Picture order here is the mcgaughy 2" drop coil next to a stock replacement 454 coil(1), the 454 spring installed with no cut coils(2), and the 454 springs with 1 coil cut(3.)
