Lower Coil Spring Mounting Cup, 66-77 Bronco, 66-75 Truck SKU: 1066

Lower Coil Spring Mounting Cup | Early Bronco & Classic Truck

If your original coil spring cups are bent, cracked, or just plain beat, it’s time to upgrade with a fresh Lower Coil Spring Mounting Cup made for the demands of your 1966-77 Ford Bronco or 1966-75 Ford F100 or F150 4x4 ront suspension. Designed for early Broncos, this critical component holds your front coil spring in place where it mounts to the radius arm—an area that takes a serious beating over time.

These cups are available in mild steel for everyday trail and road use, or polished stainless steel for those building a show-quality Bronco to stand out from the crowd. The cups feature the correct stamped bend to match the factory radius arm, so you get a clean, solid fit that installs seamlessly in your Bronco. Whether you’re wrenching on a trail rig or crafting a concourse-level build, this is a quality replacement that restores strength to your suspension system.

• Fits Early Ford Broncos – Built for proper fitment on factory-style radius arms. Also fits 66-75 F100/F150 4WD

• Factory-style stamping – Stamped with the correct radius arm contour to ensure proper coil alignment and seat pressure.

• Restores coil spring integrity – Replaces cracked or deformed originals that compromise your ride and safety.

• Available in two finishes – Choose from standard mild steel or polished stainless for a custom look.

• Great for street, trail, or show – Perfect for daily drivers, weekend wheelers, or high-end restorations.

If your stock Early Bronco coil cups are cracked, rusted, or bent out of shape, replacing them will help restore spring support for a safer, trail-ready ride.
