I have a F-150 and want to get a skyjacker 8 inch lift and want to run 37's. I would like to add a 3 inch bodylift on top of that and maybe run 38's but i hear that is almost too much work. Do i have to get a longer drive shaft or any thing if i just stayed with the 8 inch lift? any feed back would be great. thanks  

what year?

it is a lot of work, the problem is the axles of the f-150 won't last long turning 38" rubber,

35's are pushing you luck there. also you'll need to regear those axles with 4:88's  assuming you have a OD tranny.  

The TTB axle on that truck is really a poor design to lift. It is arguably the worst front drive axles ever put on a 4x4. It is known for eating tires and handling squirrelly lifted (it can do this not even lifted too). If you want a serious lift on that truck, look into doing a SAS on its front end (Solid Axle Swap). In the long run you will be ahead of the game.  

I have a 94 and Ihave a 6 inch rough country lift that has the rear dshaft maxed out.
I would make sure that u angal your rearend as much as posible.
Ihave a 3 inch body lift as well running 35's and I have plenty of room.  

Thanks for the input i think ill go with a 6 inch and  the superrunner system offered by superlift. I know i can fit 35's but if i add a 2 inch body could i fit 36? im very thankful for all the info i have recieved! thanks  

Ditto on the 8 inch lift being a driveline issue...theres a 95 F150 in my town that's big and he went with the 8 inch suspension lift and had to have a custom tom woods driveshaft made for the back that was like an extra 350 dollars....go with the 6 inch suspension, it's all bolt on....and as for the body lift....go for it you shouldn't have any issues there, i personally own a F150 with a body lift....just get your WD 40 ready for all those bolts....

oh and on a side note.....6 inch suspension and 3 inch body should be able to fit 38's on a 10 inch wide wheel if it's a street only...and a 37x12.50 should clear no matter what  

Be prepared for it to be a slug too unless you regear axles. No tune or air cleaner or exhaust is going to fix that problem. BTW, one reason drivshaft tend to fail a lot with some lifts (drive angle aside) is the greatly increased torque load on them when users fail to regear drive axles properly and reduce average drive shaft torque loading. Some seem to never even remotely consider the added load placed on drive line with big tires and stock gearing.
