Before you send it

Check these basics first.

  • Check this part number against the spring tag, old invoice, or service record for Reyco Granning.
  • Measure the length marks on the removed air-suspension arm: La / eye-to-mount length: 22"; Lb / mount-to-end length: 13-1/4".
  • Check the pivot-eye hardware before treating this as a match candidate.
  • Confirm the secondary checks: C / vertical rise: 6-5/8"; W / width / thickness: Width 3" · Thickness 1-3/4"; leaf count: 1 leaf.
  • Vehicle name and OEM numbers help narrow the search. They do not prove fit by themselves.
