Stromberg Carlson LG179013 Lead Jack 29.5" Drop Leg Landing Gear Lippert CagePin

•       Value: Authorized distributors list this part at roughly $255–294 (Hanna RV) and near $250 on Amazon — this unit lands well below distributor pricing.

•       Urgency / Season: Q2 RV pre-season repair peak is here — landing-gear failures surface during spring shakedown trips, and replacement-part demand spikes April through June.

•       Trust / Brand: Stromberg Carlson is a third-generation American RV manufacturer since 1959 — UPC verified, MPN verified, and inspected per an eight-point landing-gear protocol.

Landing gear is the part nobody thinks about until the morning it won’t crank. You’re hitched, the rig is half-up, and the lead leg has given out — trip over before it started. This is the leg that fixes that: the motor-side jack you bolt on when the original quits, the one with the mounting boss for your crank or 12V drive. It’s the part RV repair shops keep on the shelf, from a brand that’s been building American RV hardware since before most rigs on the road were designed. Bolt it on, and get back on the road.

Key Features

•       Genuine Stromberg Carlson LG-179013 → Authentic factory part with verified UPC 767773517110 and secondary SKU 45-1603. The same physical lead leg sold by Lippert as #179013 — both manufactured by Pacific Rim. Made in USA.

•       29-1/2" Lead Leg with Drop Leg + Cage Pin → The motor-side / lead leg of a tandem 5th-wheel landing gear set. Includes the drop leg and the cage pin you need for a complete swap. Follow jack (LG-179014) is a separate part, not included.

•       Heavy-Duty Steel — Load-Rated Welds → Heavy-gauge steel construction with welded weld stops that carry the load rating. Built for the weight a 5th-wheel kingpin area puts on landing gear when the rig is uncoupled. 

•       34-7/8" Total Lift — 19-7/8" Travel + 16" Drop Leg → The inner tube extends 19-7/8 inches via crank or motor drive; the drop leg adds 16 inches in 1-inch increments. The combined lift envelope handles most 5th-wheel uncouple-and-park scenarios.

•       Crank or 12V Motor Compatible → The top-mount drive coupling accepts a manual hand crank or an electric 12V landing-gear motor (sold separately — e.g. Stromberg Carlson LG-242728 or LG-196308).

•       Universal Cross-Compatibility → Replaces lead jacks in Stromberg Carlson LG-1, LG-3, and LG-183708 sets, and fits Atwood, Venture, Lippert, and Pac-Rim systems sharing the standard 17-1/2" outside-to-outside weld-stop spacing. NOT compatible with Fulton — verify weld-stop spacing before installing.

•       Powder-Coated Black Finish → Powder coat is the standard corrosion-resistant finish for trailer landing gear — it holds up to road salt, weather, and years of outdoor RV storage when not chipped through.
