Dear Welder Series…
I’m building a 1940 ford pickup. I’m having a hard time deciding on the rear suspension. I’m between a basic parallel leaf spring set up and a triangular 4 link. When it’s done the truck will be a driver. I’m not intending to haul 2 tons of rocks but I would like to be able to go to the lumber yard on occasion to pick up a few sheets of plywood or a few 2×4’s. Front suspension will be one of your MII coil over kits. Rear end will be a ford 8.8 with traction loc. Can you offer any recommendations to help me with my decision?
Jack, here are some advantages of both systems:
Rear leaf springs
- Bolt-in installation. (You will have to weld spring pads onto your axle.)
Coil-overs/triangulated rear 4-link
- Easy to change spring rates to fine tune the ride.
- The cost of new springs.
- Heavier-duty, higher quality shock than the standard ones that come in a standard leaf spring kit.
- Easy to change pinion angle.
- The coil-over has a designed ride height. Upper and lower mounts can be designed so the truck’s ride height will be where you want it with no guessing.
- Ride height is adjustable by using the lower coil-over mounting bracket holes.
- Ride height can be dialed in when different spring rate is used. (The lower spring seat can be adjusted up or down.)
I hope this helps with your decision.
