Spring or torsion?
Same wheel ends, two ways to carry the load. Put weight on them and watch what moves.
Spring axle3,500 to 15,000 lb
- Leaf springs carry the load and hang from the frame on hangers and a shackle.
- Simple to service. Springs, bushings and hangers can be replaced one at a time.
- Tandem and triple sets share load between axles through equalizers.
- 8-year axle warranty, 5 years on the leaf spring suspension.
Torsion axle3,500 to 7,000 lb
- Rubber cords inside the housing do the springing and the damping.
- Each wheel moves on its own arm, independent of the other side.
- Mounts to the frame through its brackets. No hangers, shackles or equalizers.
- Forged torsion arms, 78-hardness rubber, 10-year axle warranty.
