Drivline angles
I'm planning on buying superlifts 6 inch superrunner lift kit. One of my concerns is drive line angles. I plan to run 36x12.50x15 TSL Swampers with 4.56 gears to do the turning. Before I do all this work, I want to know if the drive line angles will be so great that I will be going thourgh u-joints left and right. Any info would be helpful.

Drivline angles
You don't mention what type vehical you have, so here it goes-with a SWB truck or bronco, you will be at the limit with the angle I think, with a LWB you should be able to get them close enough, that is to say, opposite but equal angles on both ends of the rear shaft. The front will fall where it will, it must give it up to steering angles which are just much more important. For the SWB's you most likely will have to add a CV joint at the 'case, this is also called a double cardan (at least I think that's the correct name) joint, nothing more than two u-joints on the same yoke, same will apply to the front 'shaft. With this set-up you need to angle the rear pinion yoke straight at the 'case. The CV cancels itself out. Might have to have extended 'shafts made or yours reworked for the proper length, only way to know for sure is after the lift is installed. Again, the SWB may be ok with length, LWB might need new/longer. Hope this helps.

[font size="1" color="#FF0000"]LAST EDITED ON 12-Feb-01 AT 09:05 PM (EST)[/font][p]Here is my 94 F150 with a 6 inch Superlift and 35/14.50 Mickey Thompsons. It is a shortbed truck. I didn't have to do anything to the driveline, but could have used about 2" added to the rear driveshaft. The front was fine. I will tell you, the hardest part of this lift is installing the new pitman arm. The gear puller kept getting hung up on the box. https://www.ford-trucks.com/dcforum/User_files/3a88a4320592046d.jpg
