IMG_7970.jpegJust got some new, used tires on it and am loving it. Anyone know how I can lift the front leaves about an 1”. The back of the front fender will scrape when I go over bumps while turning. (Ignore the bag coming out of the door)

Edit: from what I understand I can’t use lift blocks, but I could use a “zero-rate” block that attaches to the spring directly. What the difference in using this over leaf spring spacers?

You are correct you can not use a lift block in the front due to the possibility of them getting spit out due to the turning forces put on them vs the rear axle that only ever drives straight.

However you can buy a zero rate that bolts to the spring pack with a longer center pin. In essence it becomes another leaf in the pack but doesn't provide any additional carrying capacity. Hence the name "zero rate". Since it bolts in place instead of relying on the u bolts to clamp it in place they are safe to run in the front.
 
with the zero rate you can also move the axle forward or rearward, in 1/2" increments to help with clearance. If you move it forward to far your drive shaft may to short. If you move it back a lot the drive shaft maybe to long and bottom out, when axle is stuffed. A 1/2" forward should help the rear rub, and not give any drive shaft issues.
