How do you get more forward bite with leaf springs

keep in mind,you have to be careful not to create a situation where the RR tire can get chewed up on the spring.

If your spring perch is fixed on the axle housing (and you aren't inclined to move it), then the only way to move the rear mount of the right spring out is to move the front mount in (rotate spring CCW in top-view).
Changing the rear mount is easy if you use sliders and not too difficult if you use shackles. The cleanest way to do this with shackles is to move the frame rail out, however, if that is not practicle in your situation ..... you can insert spacers into the shackle (right side of frame mount, left side spring eye) to gain a small amount of offset.

if you are not moving the perch on the axle (the perch should be relocated for measureable effect in my estimation), then you need to see how far you can relocate the front eye (towards the centerline) BEFORE you make changes to the rear mount. a small amount of gain can be found by pressing the front bushing all the way into the spring (1/4"?) after that, it's time for the hammer, torch and welder.

while you are messing with the right front bushing, you may want to soften it up a little ..... 4 to 6 1/4" - 3/8" holes will make this bushing more complient (similar to putting a solid or stiffer bushing in the front of the left spring, this will promote throttle tightness ...... forward bite)

oh, forgot to add previously, that adding stiffness to the front of the left spring should also improve forward bite .... either by shifting blades forward (and redrilling pin hole) or by adding an extra forward leaf.

get a shorter spring. i mean the front eye to wear the axle mounts. i think chyrslers are shorter than gm so you could change from gm to chrysler springs. that will increase bite. also move the front mount up.
