BAL Manual C-Jack Parts Diagram, Size Chart & Replacement Foot Pads

Choose the right BAL manual C-Jack stabilizer by measuring your trailer frame-to-ground height and checking the jack's six-digit stamped arm or link number. This guide covers the five boxed pairs—23219, 23222, 23225, 23228 and 23231—with a manufacturer-numbered 17-part exploded-view cross-reference, original mounting drawings and direct links to matching NewRVParts products.

Manual versus powered C-Jack matters: BAL specifically warns that these manual replacement jacks do not interchange with factory motor-driven Powered C-Jack assemblies. The optional 24210 Power-Pak motor add-on is designed for eligible manual jacks; it does not make a manual jack a direct replacement for factory powered system legs.

Choose the correct size from frame-to-ground clearance

Measure the actual mounting location on the trailer frame when parked on level ground. A longer leg does not necessarily have greater weight capacity; BAL's listed static rating declines across the five models.

Identify your existing C-Jack from its stamped numbers

Manufacturer document GDS.IDCJ.001 Rev B (April 11, 2024) shows where to look for the stamped six-digit identifier on the link and on the arm. Each size has a separate number pair; use the number actually stamped on your part before replacing its arm or drive rod.

Factory exploded parts by number

The numbered rows below follow BAL's original installation manual exploded diagram. For parts 1–4, five versions are listed in ascending 19-, 22-, 25-, 28-, and 31-inch size order. The remaining numbers are factory service references rather than automatically interchangeable replacement kits. If you cannot identify the original component confidently, use the actual factory exploded diagram before ordering.

Foot pads, Airstream variation and powered conversion

BAL 23200 bolt-on foot pad pair has two 5½-in square feet with bolts and 3⅛-in mounting-tab clearance, according to BAL. Fitment is published for all five manual C-Jack families, compatible Powered C-Jacks, and 23333 Airstream C-Jack.

The 23333 is a single Airstream-specific 22-in leg with a 14-in drive rod, not a standard 23222 boxed pair. Match Airstream-specific rod dimensions rather than using a standard-length replacement solely because the leg is also 22 inches.

BAL Power-Pak 24210 converts two matching manual C-Jacks to motor drive. The conversion package includes motors, switches, circuit protection and mounting brackets but not the C-Jacks themselves or installation wire. Use BAL's genuine electrical drawing and confirm you have a compatible 23119/23122/23125/23128/23131 manual jack before installing.

Do not force a bent drive rod. BAL's service bulletin explains that a jack failing to fully retract/extend may have a bent threaded rod caused by over-torquing. Stabilizers are not axle lifts or tire-service supports; consult the factory service procedure instead of using power tools to force the mechanism.

Use BAL's factory manual for mounting dimensions, structural clearances, and installation torque requirements. Do not use stabilizers to raise the trailer for wheel or axle service.
