Will Longtube headers for a lightning/2wd f150 fit on my 2001 4Wd screw?

 

Almost certain the headers will, if you got the cats and cross over pipes as well, the guys at Dynatech said 4wd's require the y pipe made for the 4wd's, something to do with the tranny mounting. I could see that, the 4wd's have the 4r70w vs the L's 4r100. Get the headers and make your own crossover, but the headers should work no problem. Cross reference the header numbers alone, the only thing that I'd be concerned about is the EGR bung location.

 

Yes they will fit!
I have a set of long tube Lightning headers on my truck.

Thanks guys. I appreciate the help.

 

if you have the 5.4 they will. all 5.4 2wd/4wd headers are the same.
