read carefully. also look at the rest of the page. max fish=suspension jesus. reverse 4 links "work" but when i say "work" i mean that sure your truck goes up and down but any benefit of having a 4 link is thrown out the window. but if thats all you care about then go for it.
@joeytyler- any link system when improperly installed/designed/set up will change pinion angle (its bound to happen unless you know exactly what your doing) or the axle will move front or back during its range of motion. in theory the axle should go straight up and down. not saying i know how to do it the right way, but do your homework before you start welding crap in.
in other words pm dragn or get with someone who knows what they are doing and isnt going to try to convince you to 2 link that shit!
my 3 cents, because my opinion is worth more.
