i have a 1984 ford f150 2wd i was wondering if i could use 1965 rear leaf springs on the front there's 3 inches between the mustang leaf springs and the conversion kit for my truck is that a big deal??
Car springs are not made to carry the load required from a truck. You can buy helper leafs for your truck. Each one will add 1000 lbs to your carrying capacity.
Coincidently, I've owned both a '65 mustang (coupe w/289,200 hp, 3spd), and an '84 F-150 ( 300 six, 2wd, 4spd). I never messed with the suspension on the 'stang, but I did add 1 leaf to the rear axle of the truck. I paid a spring company, Jenson & Mitchell in Paterson, NJ $200 to make the conversion.
The Mustang leaf springs will not be stiff enough for a truck. I would just go to a junkyard and get some leaf springs off another truck. Leaf springs are cheap. You can probably get a pair for about $30.
No.. the weight of the truck will flatten out the springs... springs are designed to work within a particular load rating, so springs from a truck and a car may look the same, but won't preform the same....
