My Suburban has no engine, fenders, etc., so can't do any weighing. It's been X-member swapped from a 73-87 C10 and have 2" drop spindles for disc brakes and 1" drop front coils. 4" drop coils in the rear. Had a 350 sbc/TH350 trans, planning on a 5.3/6.0 swap with 4L60/80.

POL Coilovers [Aldan American] state their spring rates are:

Small Block Spring Rate = 450#, Big Block Spring Rate = 550#
