Going to try and stretch the rear leaf with a
95-05 Blazer/Jimmy/Envoy/Bravada.....4(3/1)....2-1/2...24-1/2*27-1/2....52"....1400
Do you think doubling my spring rate (just the main) would suck?

Since i now have my relocation brackets installed my options for the rear are opened up.

Now for the front thinking would the wj rears (2" longer) paired with an adj. Upper.

 

you probably wont really notice much of a difference with those rears. probably not even an inch taking the curve into account. i would get the regular s10/15 main (26 * 28). thats my plan anyways...good luck.

the 1400 rating is for the whole pack btw, the envoy packs are 1/2" thicker over all than the xj packs....
