Adapter Extension 340mm 19mm for Swivel Jack Trailer Support
Product.Nr.: 990012790
- Adapter extension to increase the reach of swivel jacks on the trailer
- 340 mm length for more ground clearance or better stability on uneven terrain
- 19 mm receiver/connection - suitable for common support systems with a 19-mm size
- Robust design for use on trailers, trailers and camping bodies
This adapter extension was developed to extend a swivel jack (rotating support for stabilizing trailers) by additional length. This is especially useful when your trailer is parked on uneven ground, when a higher frame height requires more distance to the ground, or when the support needs more working range in certain installation situations.
Thanks to the 19 mm design, the adapter is suitable for many common systems where the support or connection is designed to the corresponding size. The extension helps provide more stable support during loading and unloading, when parking the trailer, and for camping and leisure applications.
Please check the required connection size (19 mm) and the required overall length before purchase so that the extension fits your swivel jack optimally.

Frequently asked questions about this product
Three factors are key:
- Tube diameter — measured on the support wheel’s tube, not on the bracket. Common sizes are 35, 48 and 60 mm. It’s best to check with a calliper: a 48 mm support wheel won’t fit into a 60 mm bracket.
- Load capacity — this must match your trailer’s tongue load. A support wheel that is not strong enough will bend or become impossible to crank under load.
- Design — automatic jockey wheels fold in automatically when the trailer is coupled; basic models are cranked up by hand and locked into place.
Go straight to the right size: 48 mm jockey wheels, 60 mm jockey wheels or the full overview.
Common mistakes: ordering the wrong tube diameter; failing to crank the jockey wheel fully up or lock it in place before setting off; the clamp being too loose. A jockey wheel that spins freely can quickly cause damage on the motorway.
When it’s worth replacing: a worn-out wheel, a stiff crank, or a worn-out spindle. In most cases, a complete training wheel is cheaper than buying the parts separately.
