Make your own. Just get some 5" or 5.5" pipe 1/4" wall. Then get some 1/4" flat, welder, chopsaw and maybe a torch or plasma cutter. I think my top ones were 3 " and bottom 2". But the bottom ones you must angle if you are using the stock a arms. I will take pics when I put on my new shocks.
If you have 2" drop arms you dont have to cut the spring pocket. I had the uppers on 3" arms and longer lower cups. I was gonna run them w/ the brislands upper and lower arms after i broke the djm arms but it takes 2 weeks for them to make the arms. If you run the stock arms there is no way to bag w/out cutting the spring pocket
Honestly i have no clue how big my cups where. The top ones where brislands and the bottoms where like 2" tall i believe. The only pictures i have of the set up are of the broken djm control arms sittin on the side of my house. The bottom cup was just a little above the control arm. Put the truck on a level surface up on jack stands all round..... no springs or shocks just the wheel and suspension arms. Mesure from where its gonna lay to the ground. Take that mesurment and jack the tire up that high so its like how it would lay out, then mesure how much you have from the top of the spring pocket to the control arm where the plate is gonna be. Take 3" outta that mesurement then you have your top cup. Hope that wasnt too confusing but hope it helped. Let me know if you didnt get that or have any other questions, Late
