425kg 8 Inch Jockey Wheel with Rubber Wheel | GD-LF-AU-42510

Authoritative GD-LF-AU-42510 Product Data

The supplied specification publishes one 425 kg capacity field. This page does not invent separate lift and support ratings.

Size the Jockey Wheel to the Load at the Jack Position

The published 425 kg capacity belongs to the jockey wheel assembly; it is not the trailer's ATM, GVWR or total trailer mass rating. Selection should be based on the actual vertical load carried at the jockey-wheel position together with the trailer manufacturer's limits.

For OEM programs, capacity should be reviewed together with the mounting structure and real operating geometry rather than selected from trailer category alone.

Wheel Diameter Is Verified; Internal Wheel Construction Is Not Assumed

GD-LF-AU-42510 is specified with a rubber wheel and an 8 in wheel diameter. That gives buyers a clear wheel-size reference when checking ground clearance, storage space and local manual positioning.

The current source does not state whether the rubber wheel is solid or pneumatic, nor does it publish wheel width, rim material, bearing type or a dynamic moving-load rating. Those details should be confirmed from the current production specification when they matter to the application.

Travel Distance Is Not the Same as Overall Working Height

The published 10 in travel describes the available adjustment stroke. It does not by itself define the minimum installed height, maximum installed height or the mounting-reference height.

Zinc-Plated Outer Tube + Clear-Zinc Inner Tube

Those finish descriptions come directly from the supplied product data and should remain the controlling wording on the page.

The product is not described here as hot-dip galvanized, marine-certified or qualified to a specific salt-spray duration. Programs with coastal, chemical or continuous wet exposure should define their corrosion requirements separately in the RFQ.

Confirm Load, Wheel and Installation Geometry Together

Send GOODIN the expected jack-position load, trailer/frame drawing, mounting requirements, required coupling/support heights, wheel-construction requirement, ground conditions, environment, quantity and destination market. Non-standard programs can also review customized trailer jack options.

Single-Wheel Trailer-Front Support with an 8 in Rubber Wheel

GD-LF-AU-42510 fits compatible trailer applications that need a published 425 kg capacity, 10 in adjustment travel and an 8 in rubber-wheel lower end.

The correct application depends on the actual load at the jockey-wheel position, installed height window, mounting geometry, wheel clearance and ground conditions—not simply whether the trailer is called a boat trailer, box trailer, utility trailer or caravan.

Use the Jockey Wheel for Controlled Local Alignment, Not Road Travel

A wheel-equipped jockey jack can assist with coupling, uncoupling and short local repositioning when the trailer, surface and supported load permit. Actual rolling effort depends on load, slope, surface condition, wheel construction and trailer resistance.

For a broader comparison of wheel-equipped jacks, dollies and powered movers, see GOODIN's tight-garage trailer mobility guide.

An 8 in Diameter Helps Define Clearance, but Does Not Define Every Surface Limit

The supplied data identifies an 8 in rubber wheel. Buyers can use that diameter when reviewing local ground clearance and physical envelope.

Because wheel width, solid/pneumatic construction, rim type, bearings and dynamic rating are not supplied, the page does not promise universal performance on gravel, sand, grass, thresholds or other difficult surfaces.

Match the 10 in Travel to Real Coupling and Parked-Support Positions

Travel distance describes available adjustment, not the complete installed height range. A correct fit still requires the current model drawing and the same measurement reference on the target trailer.

If the required coupling or parked-support position falls outside the installed working window, capacity alone cannot make the jockey wheel a correct fit.

425 kg Is the Jockey-Wheel Capacity, Not a Trailer-Mass Specification

The target application should be reviewed using the real vertical load at the jockey-wheel position. Trailer ATM, GVWR, payload and axle ratings describe different parts of the towing system and should not be substituted for the jack's own capacity field.

Mounting structure and local frame strength also remain part of the load path.

Confirm the Actual Mounting Interface Before Treating It as a Replacement

The supplied summary does not publish tube diameter, clamp or bracket dimensions, hole spacing, fastener requirements or a frame-size range.

OEM and replacement buyers should therefore use the current GD-LF-AU-42510 drawing rather than assuming another 8 in jockey wheel is dimensionally interchangeable.

Specify Corrosion Exposure Separately from the Basic Zinc-Finish Description

GD-LF-AU-42510 is specified with a zinc-plated outer tube and clear-zinc inner tube.

No coating thickness, salt-spray duration, hot-dip galvanizing claim or marine certification is published in the supplied data. Applications with aggressive salt or chemical exposure should add their environmental requirement to the RFQ.

GD-LF-AU-42510 is a manually adjusted trailer jockey wheel. The 8 in rubber wheel can support compatible local positioning, but it is not a road-running trailer wheel. The source does not publish a separate dynamic moving-load rating, so the 425 kg capacity should not be reinterpreted as a guaranteed rolling load.

Information to Send Before Approval

Provide actual jack-position load, trailer/frame drawing, mounting method, required coupling/support heights, wheel-construction requirement, ground surface, intended manual-positioning distance, operating environment, quantity and destination market.
