I have to disagree. The full traction are independant of the crossmember. Each bracket for the lowers is very easy to install and the upper brackets are just a bit more difficult because they are inside the frame rail some. But all in all the brackets should be able to be installed in about a hours time. You will spend twice as long cutting the old off then putting the new on. I didnt deciede to bolt it all on though. I simply bolted the brackets on with the crossmember bolts then marked every location of holes in the brackets for bolts to the frame, then removed them and flap disk'ed the frame rails and then put them back on and plug weleded every hole for a bolt to the frame, and did 2" stich welds all around each bracket to the rails.
Now I can simply just remove the TC member if need be, no differnet then stock except 2 extra bolts per side, and if I need to remove a upper arms its only one bolt (yes a 8-9" bolt though) or lower its only one bolt.
