Yes and no. We have it but all we use is the brackets that stick out and hook to the rails for hanging chainfalls before you land the car. (we drill two holes in the actual rail to keep it from pivoting in rail clips). We don't use any more of the kit. Land car, remove gusset (sidestile extension), only one side at a time and remove first piston. We normally just choke them -- they make a threaded eyelet but you lose 6-8" of drift after your mouse it. Then carefully LAY THE PISTON DOWN IN THE PIT AGAINST BACK WALL OR SIDE OF CAR. Rest it against wall and put a rag between to eliminate scratching. Same for piston 2 if a a 3 stage. Replace checks as the pistons are hanging right in front of you with chainfall. Don't try it any other way. You may have to lay on the cartop if out of drift, etc. Then replace packing as you go. This is a dangerous job and it is difficult. But we have done 10 or so and we got really really good at it but would rather not do it any day of the week. Pays well but not even worth it -- its war. You'll see. Gonna need a piston clamp if you have to repick lower.
