★ High-quality reproduction to original military specifications. The U-bolt ensures correct clamping force between leaf spring and axle, essential for safe road holding and protection of the centerpin.
Application
Ford GPW 1941-1945. The narrow A-575 U-bolt is used at 7 locations: 4 rear (both sides of axle) and 3 front (left driver's side and inner right passenger side). For the 8th point (outer right passenger side front), the large A-574 U-bolt is required due to larger Dana 25 axle diameter.
Installation notes
Position U-bolt clips around the axle on both sides of the leaf spring pack. Secure to the mounting plate beneath the leaf spring with lock washers and nuts. Torque to specification for 7/16" U-bolts. Check tightness of all U-bolts after short running-in period (50-100 km).
Compatibility
PLEASE NOTE: For Ford GPW, 7 pieces A-575 (narrow version) and 1 piece A-574 (large version) are required per complete vehicle. The A-574 is needed for the right front side due to difference in axle diameter. Do not use A-575 exclusively for all 8 points — this will result in incorrect mounting.
Historical context
The U-bolt mounting system was standardised by Ford and Willys for the military 1/4-ton jeeps during WWII. The system allowed for simple assembly and maintenance under field conditions, where defective springs could be replaced quickly.
