THE CHEVY SPRINGS IV GOT ARENT THE 63 I THINK THERE 57s AND ALSO WHAT DID IT TAKE FOR U TO MOVE REARS UP FRONT I WANT TO DO IT ALSO ON MY 83 WILL IT MOVE THE AXLE ANY AND CAN I GET AWAY WITHOUT HAVING TO AD HIGHSTEERING

 

Might want to check your CAPS LOCK key, it is stuck on and that = YELLING.

57" Chevy springs; measure and see.
Measure what? Front and rear lengths from the center pin. Move spring hanger forward an amount equal to the difference in front half length of the new vs. stock springs. Move the rear shackle hanger back the difference of the rear half length of the new vs. old springs or use a shackle as many inches longer as needed:

Rears up front:

Crossover steering will help but if you have an adjustable/dropped drag link and can flip the ball on the steering J-arm then you may be able to keep stock steering.

 

thanks alot sorry bout the caps im not yelling if any ony has done the od ball chevy springs would like to see how good they flex thanks for all ur help

 

my rear springs are 20 1/2 center of front hanger to the center pin and the front is 23 1/4 and i want to put my rears up front so what do i need t move or drop and how far and i would like to keep the wheelbase the same thanks again

 

Putting rears up front is usually done to move the front axle forward for better tire clearance with the back of the wheel well. But if you want to keep the w/b the same, you'll need to move the spring hanger (the thing up front where the springs bolt to the frame) back 2.75" (23.25 - 20.5 = 2.75) in order to keep the front axle where it is now. That would keep the wheel base the same.

 

would i have to get a new drive shaft made if imove my wheel base uf that far the way it looks now i will need one

 

Probably so, may need a longer travel slip yoke depending on how much travel the springs have. Or if the shaft is just too short, a spacer can lengthen it:

does any one have pictures of the 57 inch chevy springs installd would like to see how they flex thanks

 

are you sure they are chevy springs? 57" sound like Ford springs.

people have been trying to help you out but IMO you need a little more effort on your part...

 

here's some facts about leaf springs that will help you decide what you want:

the thinner the leaf the more it will flex and better it will ride.

the more arched a spring is the less it will flex but more it will lift.

a spring pack with lots of thin leafs will ride and flex worlds better then a pack with only a few thick leafs.

leafs with round and tapered cuts will flex more then blunt square cuts.


now find some ideal springs, build a bastard pack out of them and tweak it to get the ride height you want.

*a hint, a lot of wagoneer springs have 7 or 8 leaf packs and they are all tapered cut and thin. they are very flexy, might be a good idea to add them to your toyota main or another main that will fit.

also check the install instructions for Trail Gears rear kit, http://www.trail-gear.com/pdf/classi...structions.pdf their springs are 56" long (it is what I am installing on my '81)
move the front hanger forward 6" and the shackle mount back 2-3" ...

 

Part of your whole flex problem could be your shackle angle.

And frank i am also interested in learning about your webber setup. How did you adapt it? or where to find the adapter?

 

do you have any good pics of your setup? i was looking at doing that but i was worried the front end was close to the max weight for air shox. how soft is the front?
