Syjacker long leaf added 2" which leveled my Bronco.
ONly issue i had and i heard this from other reviews is that was a little long on the rear and it edge would be up againts the top leaf. I cut off 1/2" to make it work. I used a milwauke band saw with no trouble. by had or jig saw would take much longer. Too me it was a better solution than to add a 2" block.
Put spacers on my truck with no problem, The first 100mi. bottom spacer broke and had to drive 18 hours on bag sideways under truck. The plastic tabs broke off and could not be repaired. Would never by plastic item again. Made steel spacers out of pipe and two cap plates on each end with bolts welded from inside of cap plates. Cant believe they put plastic under 5000lb. air bags???? DO NOT BUY THIS PRODUCT FOR UNDER YOUR BAGS!!!!!
