heavy load Rear Suspension?

[Lmackattack]

add more springs or a walking beam set up. I added a walking beam to my 1/4 frame end dump and it lets the suspension travel yet it keeps it from leaning when the box is raised. I think the beam is 1/4" x 1/4 " square....aprox 6.3mm x 6.3mm

I've seen others use the spring pack from the F350...they F350 springs don't come ready assembled like the tractor truck kits. That way, you can choose how many leaves you have so you can build the springs to your own spec
