63-87 Chevy & GMC C10 Front Lower Bag Cups

63-87 C10 Front Lower Bag Cups (Pair) - #125-2100

These front air bag cups provide a simple, affordable, and proven solution for converting factory front suspension to air ride using stock lower control arms. Designed to sit in the original coil spring pocket, they allow a D2500 or D2600 air bag to mount securely in place of the factory coil spring.

Each cup drops directly into the lower control arm spring pocket and is retained by the vehicle’s weight, just like a traditional spring or air bag. No welding or bolting is required, making this an ideal option for clean installs and budget-friendly air ride conversions.
