Question:
I have a camp trailer that I would like to upgrade the suspension to a heavier duty. It is tandem axle with the following: double eye leaf springs, 25 1/4 eye to eye length, 1 3/4 wide, with 4 leafs. 33 axle spacing with 3500 lbs. capacity per each axle and 2 3/8 axle tube dia. I would like to replace all existing, suspension parts with heavy duty upgraded parts including: Leaf springs, equalizers, shackle links, tie plates and bolts. I have looked at part no. K71-359-00 on your web site, but it does not include the leaf springs. Do you sell an all inclusive upgrade kit? What do you recommend? Thank you

Hey Wes, the # K71-359-00 is a great base to start with to upgrade your suspension since it comes with a lot of the components needed.
For 3,500 lb axle springs in the exact length you need you'd want the part # DX23CR. Are you wanting u-bolt plates too?
