Before you ask
Check these points first.
- Compare this part number to the spring tag, old invoice, or service record for HUTCHENS TRAILER.
- Measure the length marks on the removed spring: La / a-side length: 23.11 in; Lb / b-side length: 22.87 in.
- Check the spring eye hardware before you treat this as a likely match.
- Confirm the secondary checks: C / camber / free arch: 189/170; W / material width / thickness: 2.99 × 1.38 in; leaf count: 1 leaf.
- Vehicle name and OEM numbers help narrow it down, but they do not confirm fit by themselves.
