AndreThanks for the link but I've already read it and learned agreat deal about tires.I've read multiple threads and sort of got the basics but I need more spcifics especially to my 93 coil sprung trooper. Would be nice to be able to use 200.00 leaf kit but of course I can't, and darlington wants both arms and a leg for my kit, and I see they want 109 for poly coil spacers that don't amount to much more than a pair of roller skate wheels and 80 for 1/4" plate spacers that I could easily fab given I had a drawing. So I guess what Im getting at is I need more specific details/instructions as ready made kits in my opinion are at least double what they should be. Lastly in reading threads I find that it is often assumed that everyone knows all the terms where as alot of us newbies have had little exp with suspensions and sometimes need to be pointed to specific diagrams/directions/manuals.I read this myself and realize it sounds whiny/bitchy but it is CERTAINLY not intended to. <img src="/forums/images/graemlins/cheers.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" /> p.s I understand the torsion crank part found good info on that.
