BAL Kingpin Tripod Parts Diagrams: 25033, 25035, 25037 & FASTJACK

Identify BAL fifth-wheel kingpin tripod stabilizers by exact model before buying a replacement, extension leg or gooseneck adapter. This guide distinguishes the 25033 Standard, 25035 Deluxe and 25037 Classic gooseneck tripods from the newer 25066 FASTJACK Weekender and 21100000 FASTJACK Full-Timer. Use the BAL 25035 factory exploded drawing, part-number table and product photos below to identify replacement components. A separate section covers the FASTJACK Weekender and Full-Timer.

Stabilizing only: kingpin tripods do not replace the fifth-wheel landing gear or the trailer's leveling jacks. Level and support the trailer on its approved landing gear first. BAL expressly warns against lifting the front of the trailer or taking weight off the landing gear with a tripod.

Choose the correct BAL tripod or accessory

The current BAL model pages give the height ranges shown below. Different adjustment mechanisms and coupler adapters must not be substituted solely because the products all have three legs.

Exact BAL MPN Tripod type Current height Important distinction
25033 Classic tripod 40–52 in No extension legs supplied; accepts optional 25001 extensions when appropriate.
25035 Deluxe tripod 41–68 in The only model whose 28-item exploded factory drawing is mapped below.
25037 Classic gooseneck tripod 29–41 in For a compatible 2-5/16-in gooseneck coupler; not a FASTJACK.
25066 FASTJACK Weekender 40–60 in Manufacturer-published spare parts below specifically identify Weekender.
21100000 FASTJACK Full-Timer 39–61 in 23-lb full-time version; do not assume Weekender repair parts interchange.
25067 FASTJACK adapter Adapter only Maker confirms compatibility with 25066 and 21100000; no tripod included.
Older-versus-current specifications: an older BAL brochure lists 25033 at 44–50 in, 25035 at 44–66 in and 25037 at 34–38 in, while current BAL pages identify 40–52, 41–68 and 29–41 in respectively. The older FASTJACK brochure mentions 37–60 in; the manufacturer's current 25066 page specifies 40–60 in. These are publication differences, not evidence that a particular older physical unit can reach a newer model's limit. Measure the installed assembly and check its label.

Tripods and FASTJACK accessories

Compare the Standard, Deluxe and gooseneck tripods with the two FASTJACK models below. The 25067 adapter is sold separately and does not include the tripod.

25035 Deluxe replacement parts by number

The numbered components below belong to the 25035 Deluxe tripod. Do not use the same part numbers for 25033, 25037 or FASTJACK models without a separate manufacturer match. The factory 28-item chart also identifies the remaining screws and washers.

The manufacturer's illustrated assembly also distinguishes the three base-pad locations: two support legs have chain arrangements different from the telescoping jacking leg. The chain hook and locking clasp help tension and retain the tripod's base spread. Incorrectly assembling a chain or drive screw can defeat stability; consult the original BAL assembly illustrations.

FASTJACK Weekender and Full-Timer components

BAL FASTJACK Weekender and Full-Timer ratcheting tripod components Original schematic showing a FASTJACK top flange bracket and padlock, three ratchet adjustable legs, tension handles, cross-link arms, large foot pads and a separate 25067 gooseneck adapter. Weekender spare parts 825103, 825104, 851106, 851107, 851108, 851109 and 851113 are not assumed to fit Full-Timer.

Overview of the Weekender and Full-Timer FASTJACK components. The Weekender spare-part numbers in the following table are published by BAL; do not infer these components are interchangeable with the heavier Full-Timer without an exact manufacturer cross-reference.

FASTJACK Weekender replacement component references

BAL replacement number What it identifies Compatibility check
825103 Tripod base assembly Weekender 25066 only; verify original revision
825104 Adjustable leg assembly Weekender 25066 only; not established for Full-Timer
851106 Leg footpad Weekender 25066 only
851107 Center bracket Weekender 25066 only
851108 Cross-link arm Weekender 25066 only
851109 Clamp Weekender 25066 only
851113 Padlock Weekender 25066 only

On the FASTJACK, the top bracket attaches to the kingpin's lower flange and the three independently adjustable legs use ratcheting tension handles. The BAL instructions require a secure top bracket and footpads on a stable surface, and warn not to over-tension or use the tripod as a lifting device.

Gooseneck: two different adapter situations

BAL 25037 Classic gooseneck tripod already includes its coupler adapter and is intended for a compatible 2-5/16-in gooseneck setup. The separate BAL 25067 FASTJACK gooseneck adapter is confirmed by BAL for 25066 Weekender and 21100000 Full-Timer only. The adapter replicates a 2-5/16-in ball for the gooseneck coupler; it is not automatically a Classic 25033/25035 adapter.

For the Classic 25033 and 25037, BAL publishes optional 25001 extension legs with adjustment positions spaced 3 in apart. An exact NewRVParts product for 25001 was not confirmed, so it remains plain text instead of linking to a different part.

Follow BAL's instructions when assembling, folding or adjusting a tripod. Keep the feet on firm, level ground and avoid finger-pinch points when changing leg positions.
