I've got some serious axle wrap going on. I have a 2016 F150 4x4 5.0 with a Roush supercharger. I am currently working with a tuner and the power is going up.... both good and bad. Any time I punch it in 2wd the rear tires spin, and when it shifts or I let off its a horrible bang/thud. If nothing spins, all is good.

Old school lakewoods, new school caltracs, or something else? What are others running and whats the good or bad about them?

 

Caltracs are nice because they don't screw up ground clearance. A bunch of the Lightning guys run them with 600/700 to the tires and they do a nice job controlling the axle. They are also good because there aren't any rubber or urethane bushings to dry up, crack, rot, etc.

I had the under-axle 6ft. Johnny Lightning bars on my Lightning. They worked perfectly but they did reduce my ground clearance considerably. My Lightning was mild and only made 425/520 to the wheels, but I'm sure they would be fine for higher power levels too.

 

I tried to run the Pro Comp bars on my 2014 Tuscany and am also working with a tuner on my Roush Stage 2. I went to the dealership to swap out my BFG KM2 M/T for Toyo open country at2 xt tires as I was shredding them w/4.56 gears.



The bars bent on the lift??? Going to get my money back and go with something else.

 

I went to CalTracs but I'm confused. Oh...I see if your truck has been lifted you need to contact them. If these don't allow articulation then next stop will be One up Offroad.
