Axle & Spring Seats/Top & Bottom Plates Overview
Axle and spring seats and plates clamp the spring to the axle and locate everything under load; worn or cracked seats let the axle shift and cause alignment and handling problems. Van Horn Truck Parts carries axle seats, spring seats, and top/bottom plates cross-referenced to Automann and OEM part numbers.
Match by axle diameter, spring width, and plate type/hole pattern.
Mechanic & Fitment Specs:
- Match by: Axle diameter, spring width, plate type/hole pattern
- Cross-references: Automann, OEM
- Buying tip: Replace cracked seats promptly — a shifting axle wrecks alignment
