click on any of the links on ssd.com's page. on the right hand side there were be a build your own custom kit link.once you do that you'll need to pick out a four link. my buddy got his with the air zenith, 5 gal chrome tank,smc's 1/2 valves, 4 slam's bags, 7 switch AVS locking swithbox, 50ft 1/2 air line,50 ft 1/4 air line,3 gauges, torsion bag brackets, triagular notch,super lift 4-link and we upgraded the lower bag mounts for the bars to the square type far around $1800 shipped.
I did the back first. Why? i found better pictures of the back. your lower bars need to be parallel at ride heigth, and the bag need to fully compress when laid out. Don't forget about your pinion angle, it needs to stay around -3 to -1 (someone PLEASE correct me if I'm wrong here)a $10 angle finder will be your best friend.
the front wasn't as bad as i thought it would be. You have to cut the shockmount away and that leaves a hole in the lower part of the frame you need to fill. The LCA needs to be trimmed also, and relocating(flipping) your ball joints will help.
remember:NO RUBS!!!bags, wheels, tires,air line on sharp sheet metal.
take your time and have fun.if you get mad STOP. There's always tomarrow.
