Sold in pairs (2).  Custom leaf springs for your 1/10 scale truck.  You will need to provide detailed measurements... or state one of my set ups..(Front and or Rear TF2 Long Leafs, Front or rear BBV5 Long Leafs, Sever, ect). Shackles, and mounting hardware is included. This is a premium express service.
 
If you are designing a set of leafs, It is best to have the truck setup with body mounted so you know the distances and where the axle placement will be.
