ok i have searched the board and have come up empty handed. i am building a s-10 body on a blazer frame with full exo. we figure it will wiegh in around 3500lbs. i was going to run coilovers but i cant afford 1600 bucks right now with all the other stuff i have to buy. so i am thinking aerostar coils on the rear. but i dont know about the front. i was thinking early bronco 5.5 lift springs? the rear will be three linked and the front probly 4 linked. so does anybody have any sugestion on this?????????

thanks jeff

What? Are you just going to shove it around? 3500# sounds right with no engines :flipoff2:

How high are you going to need it to be? Sounds way off 5.5 lift springs versus minivan coils :confused:

it has a 350/700r4/205 with d44 and 12b axles i am going to run 37" tires. 3500lbs should be close with the people i have talked to. from what i hear the aerostar coils are 19" long? i am trying to figure this out as this is my first goaround with coils. maybe tj coils?

First I bet it will weigh over 3500lbs, alot of the small tube buggies almost weigh that much.

Second I think aerostar coils are way to soft for something that heavy. A TJ spring would be more in the ball park and give you lots of aftermarket options if stock one's are too soft. EB lift coils in the front sound good for your weight.

COILS:
OEM XJ (cherokee) is supposedly 147 lb/in rate.
OEM ZJ (grand cherokee) with 4.0 is supposedly 190 lb/in rate front and rear.

Aftermarket XJ coils:
Tera 4" TJ coils have a 200 lb/in rate , 20.25" tall unloaded
Rubicon express (RE) 4.5in ZJ coils are 240 lb/in. give 6"-6.25" of lift on an XJ 22" tall unloaded
RE 5.5XJ coils are 4.5ZJ coils.
Rusty's 6.5" lift coil is 22" long, 12 wraps of 5/16" stock
Rusty's 4.5" coils give 5" of lift and have a 150 lb/in rate, 22" tall unloaded

Some stock XJ coils might be good in the rear, then get some 20-22in coils for the front 200-250ish sprign rate might do but will feal soft with all your weight...

thats All I got...

I would bet that were looking closer to the 4500-4800lb range. I would have to guess that my truck is in the 4000-4200lb range and that is with toy axles and a V6. Isn't a K5 around 5500lbs? I can't see loosing more than 1000lbs tops by going with the S-10 body.

I would say 5000-5500 for blazer, then you figure a good saving going to just an s-10 cab, however he gains some of that back with the Exo. i bet a total weight saving of 500-800lbs so i agree with your wieght prediction

I've got a set of James Duff 3.5 inch lift coils that would be perfect for what you are building.

Old man emu springs, medium duty for disco/rangie classic.

Part number 751

16" free height, and 200lb progressive. 5" od I believe. Around 45.00 ea

If retained will stretch quite well without fatigue.

OME makes a ton of springs for Rovers, with all load rates and lengths imaginable.

I too think you will end up closer to 4500.

(a disco is around 6k and quite squishy on these springs)

yha sam's slinky is way lighter than a k5, and areo star coils are way soft on it. hell even sami guys think they are soft.

I had the same logic as you running areo rear and older Bronco coils front. What happened is the low spring rate of the rear areo would take over do all the work while the heavy spring rate of the bronco coils would keep the front of the truck from flexing. I'm running areo coils F&R on my truck with a rear t-bar sway-bar with about 50/50 flex and like it alot.
