Hey Mr. Billy, I'm building a 1957 Chevrolet 3100 P/U. It will be powered by a '97 LT1 w/t56 six speed mildly hopped up. I would like your input on my spring and suspension package.
Here is the basic approach I'm taking;
1) Leaf springs at all four corners as stock, I refuse to butcher up the truck w/IFS. Reversed eye front for 3" drop, stock ride height rear.
2) Add on sway bars, front and rear.
3) QA-1 single adjustable shocks.
4) Power rack & pinion steering mounted to the straight axle w/telescoping shaft.
5) Probably a 235/70/15 front, 255/70/15 rear 7"f, 8"r wheels.
6) Add on traction bars, slide link or slapper bar.
Here is what I want;
1) Haa, to borrow the ad slogan, Ride like a Cadillac and handle like a slot car.
I realize this is all about compromise.
2) Decent traction without wheel hop issues for an occasional drag strip run.
3) Rear spring setup for superior ride quality(will never carry any load in the bed)
4) Want to work with Detroit Eaton Spring for the package.
Here is what I know from research;
1) Curb Weight 1995#front, 1365#rear. Payload rating 1555#/100% rear.
2) Factory spring specifications; FRONT-Semi-elliptic, chrome carbon steel,6 leaves, load @ opening height firstname.lastname@example.org", average rate of deflection 304# per inch, rated capacity 1000# on the pad-1170@the ground. REAR- Semi-elliptic, chrome carbon steel, two stage, 7 leaves, load @opening height 1100-1200 @ .440", average rate of deflection(pounds per inch)(1st stage-175# @140-425(2nd stage-237@ 800-1050), rated capacity-1100#on the pad, 1250#on the ground.
3) Detroit Eaton has on the shelf springs and can custom build. On the shelf springs available; FRONT- 6 leaves w/304# spring rate & 865# load rate. OR
REAR- 4/3 leaves w/1150# load rate(no spring rate given) OR 8 leaves w/248# spring rate-1425# load rate.
4) 114" wheelbase, 60.5" track width front, 61" track width rear (wheel c/L to c/L)
With requested requirements and the information supplied, how would you set up the old buggy?
Comments welcome from others too, especially if you've worked with four wheel leaf spring packages.
