Chevy 1925, sorry about not getting right back at you! As for trussing the axle, my builder thought it wasn't necessary due to to the size and strength of the axle. I live in the mountains and drive 70/30 dirt to pavement and see real nasty washed out roads with dips and potholes you could sink a stock truck in!! The truck was done because it was necessary to make DD more comfortable, quicker and fun. I will eat the roads around where I live now instead of getting eaten... Bump stops, AMP research steps and some PIAA'S lights are coming next. I always wanted bump stops because I see future dune and Baja trips which means the truck could get air born! A project like this takes awhile and I have some other things like scratching the frame down front to back to be painted black that are being done also. Adding more on the table meant me not seeing my truck longer and I need it back so until next time!
