I am installing a 99 Lightning Motor, Tranny, and rear end into a 99 F-150 Supercab and wanted to know if I need a custom made driveshaft, as the one from the lighting will be short. Will the driveshaft from a 99 Harley supercab f-150 work and also handle the extra power from the lightning? I appreciate the help, thanks.

 

Welcome ! You'll need a driveshaft from a newer model HD that is supercharged, using the 4R100, and in your wheelbase. If not available call these guys www.dennysdriveshaft.com Ask this question in the HD area of the board for a quicker response.
