I'm going to order my 3.5" CAGE lift shortly and I'm going to go with J&M as well. They still have their pricing where CAGE used to be and Mike is informative and has first hand experience with these kits. He loves his kit on and off road but he did mention that if he had it to do all over again he might go with a 3.5" and 2" BL as right now he's not running any body lift.
J&M Offroad:
76-77 3.5" Lift Kit - $750 (no track bar bracket or drop pitman arm)
Includes: Coils, Leafs, 4 degree 14-piece bushing kit, exttended front shock mounts, (4) CAGE shocks [32.97/19 & 29.4/17.35]
Long Travel Radius Arms - $625 w/ purchase of lift kit ($650 without)
Front Shock Hoops - $156 (subtract $40 for the front shock mounts in kit)
Rear Shock Hoops - $150
Additional Shocks - $36 each
I am in no way affiliated with J&M but I priced everything from several distributors and found J&M the easiest to get a hold of on the phone and very informative. I'm looking at placing my order this week.
