Rear Coil Spring height? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Jarwood · 12-26-2011, 11:55 PM

I need to pick your brains! I cut my front coils to get my height down to 29" from floor to center of my fender. I like the height for now in the front. I have not touched the rear but want my rear to be 29"-30". I do not want the rear of the truck to sit lower than the front. I need to buy rear coils. Here is the million dollar question. What size rear drop coils do I need to buy to get my truck at 29"-30" from floor to middle of fender? Ohyeah I have 20" wheels with 275/40 tires.
Thanks!

Any help? I am thinking a 4" lowered rear coil????

**N2TRUX** · 12-29-2011, 12:04 AM

What is your height now?

Jarwood · 12-29-2011, 12:11 AM

I am assuming they are stock springs...just wore out. If I measure from the floor to the middle or center of the rear quarter at the highest point is 32'' tall.

I was told that a new stock coil will lift the truck dramatically...I would like to stay around 30''..I have two sets of lowering blocks if needed, so if I can get new coils in and put the truck around the 30'' mark would be great.

How much lower do you want it from where it is now? I would look into blocks and keeping your current springs if you're needing 3" of drop or less. They don't sell 3" blocks, but you could get a set of 1" and a set of 2". There's even a good thread on the board on how to make your own 2" blocks on the cheap.

Jarwood · 12-30-2011, 04:45 PM

Yeah I was thinking about just doing that. The only problem is I want the rear end height to match. Dont like one side being 31'' and the other 32''. I guess I could make the difference up in lowering blocks. I would like it to be around 30", which is 1 " higher than the front.

Thanks for the reply.

what do you suggest. I am going to buy coils, but not sure what size to get...maybe 4" lowered springs and start there???

I got a set of U bolts for a 1" or 1.5" drop block, but no block lmk if interested.

Ece makes drop springs as "big" as 3" dropped springs

Jarwood · 01-01-2012, 11:18 PM

Just ordered new rear coils 4" lowered, front and rear sway bars, and the deluxe trac bar from CPP.

Thanks for the help guys!

Keep us posted on how you like the REAR sway bars.

The front bar is a HUGE upgrade, a must do for these trucks
