The Multiquip 1JA104S Jack Assembly with Caster is a genuine OEM component designed for the TRLR-10 trailer. This direct-replacement assembly restores full jack and caster function to your trailer, ensuring stable positioning and easy maneuvering when hitched or unhitched. Sourced directly from Multiquip, part 1JA104S is built to the same specifications as the original unit installed at the factory. If your TRLR-10 trailer's jack is worn, damaged, or no longer operates smoothly, this is the correct replacement assembly to restore it to working order.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the jack mechanism and caster wheel operate as intended under load.
- Complete Assembly — Supplied as a full jack and caster unit, so installation is straightforward with no need to source individual sub-components separately.
- Confirmed TRLR-10 Fitment — Verified for use on the Multiquip TRLR-10 trailer; use part number 1JA104S to confirm compatibility before ordering.
- Smooth Trailer Positioning — A properly functioning jack assembly allows the trailer to be raised, lowered, and repositioned with control, preventing uneven resting and hitch strain.
- Caster Mobility Included — The integrated caster enables lateral movement of the trailer tongue when detached from a tow vehicle, reducing manual effort during placement.
The jack assembly on a trailer serves as the primary support and leveling mechanism for the tongue end when the trailer is unhitched from a tow vehicle. It allows the operator to raise or lower the front of the trailer to match the hitch height and keeps the trailer stable while parked or loaded. The integrated caster wheel enables side-to-side movement so the trailer can be manually repositioned without lifting. When the jack mechanism wears out, seizes, or the caster fails, the trailer becomes difficult to maneuver and may rest unevenly, increasing stress on the frame and hitch components.
