4g cut springs

Lots of 4th gen guys have cut springs on here. You should be fine, keep in mind it will settle a little to

Many have cut their springs, but most of the stock 4th gen coil springs should not be cut(they are not the correct type that can be cut safely). Some people do it anyway, but I highly recommend against it.

The only type of coil spring that can be cut safely is tangential(the other types are square and pigtail). The rear springs on 4th gens are pigtail on bottom and square on top, so can not be cut safely. The exception to that is if the springs are progressive with tightly wound coils near the top(I know for a fact the rear RT springs are like this....not sure about other models). Technically you shouldn't cut the progressive(tightly wound near the top) square end springs either, but after cutting them the coils are wound so tight they are nearly square ended again. Once you put very light weight on them(barely start to set the truck's weight down) they flatten out and sit in the spring perch safely.

I bought a set of RT springs for my quad cab and cut them as much as I could(I ran out of tightly wound progressive coil) and I got nearly 1" of rear drop. Also, even if I had more coil to safely cut, I couldn't have because the spring was becoming too short to fit. There is nothing that holds it in place other than the vehicle's weight, and if I cut the spring any shorter I'd be afraid of it falling out if I hit a big bump or something that fully extends the axle.

Check out this website, a lot of good info here:

Also, NEVER cut with a torch, and NEVER heat springs to let them fall/sag and cool. Doing either of these is a huge safety concern.

I say cut the fronts, 1/2 a coil at a time (1 full coil is about 2"), and buy McGaughy's 2" drop springs for the rear ($200), cutting them to taste. The OE rear springs can't be cut more than 1 coil safely, which is only worth about an inch (trust me, I tried). You don't HAVE to have a panhard bracket, but your axle will be off-center w/ a 2"+ drop in rear. A Spohn adjustable panhard bar will re-center your axle, but it won't fix the geometry problem. Only a relocation bracket can do this (which can only be bought in a kit or fabbed up). You will need shorter end links for the rear. I actually considered going this route, but for $360 bucks I think I'll just get the BellTech kit from Jeg's. It has springs, shocks, end links, and bump stops. I'll just fab my own panhard bracket, unless I can convince BellTech to include one with their kit. If you decide to go the "cut" route let us know how it works out...

I cut 1.5 colis off the rear for a full 2" drop. No issues on handling or anything like that. Not sure what the danger in cutting more than 1 coil is. There are others that have cut 2-2.5 coils off the rear. I have had 980 lbs in the rear with only about 3/4" of sag from the load.

well so much for a cheap drop kit lol.. guess ill just cut the rear this weekend to level it out till i save up for a drop kit.

Me and dad bought trucks the same night, both 12 Express QC trucks. I did the 963SP bell tech kit, my dads truck got the springs cut and stock shocks. They sit 100% identical and ride and tow 100% the same hauling the same 21' bass boat.
His has a full coil out of the front and two coils out of the rear making a 2"/4" drop like my bell tech. I did remove the bumpstop cups on his front and mine, and I cut his rear bump stop in half.
