600 lb Zinc-Plated Trailer Jack with 220 × 65 mm Rubber Wheel | LF-J7-60

The Current LF-J7-60 Specification Set

A Wider Wheel Changes Surface Contact and Packaging at the Trailer Front

The known wheel footprint is 220 mm in diameter and 65 mm wide. That makes both dimensions relevant when checking ground clearance, nearby frame members, storage space and the surface on which the trailer will be positioned.

The specification confirms rubber and a metal rim, but does not define solid/pneumatic construction, rim alloy, axle, bore, bearings or a dynamic rolling-load rating.

Keep Product Capacity Separate from Wheel Manoeuvring Capacity

LF-J7-60 is published with a single 600 lb capacity value. The available data does not identify that value as a separate static, lifting or manoeuvring rating.

Do not use 600 lb as an automatic rolling-load limit for the wheel assembly unless the applicable rating basis is confirmed.

Zinc-Plated Outer Tube and Clear-Zinc Inner Tube

The finish is specified separately by component: zinc plating on the outer tube and clear zinc on the inner tube. These terms should not be rewritten as hot-dip galvanizing or converted into an unpublished corrosion-performance rating.

For routine cleaning, lubrication where specified, wheel checks and visible coating-damage inspection, continue to GOODIN’s Trailer Jack Maintenance Guide.

LF-J7-60 Is Not Just an LF-J7-1 with a Different Capacity Label

The larger wheel envelope and higher complete-unit weight mean the two products should not be treated as drop-in substitutes solely because they share LF-J7 naming and plated tubes.

Confirm Mounting, Travel and Operating Geometry Before Approval

The current specification verifies capacity, wheel envelope, wheel/rim description, tube finishes and net weight. Handle style, travel, installed height range, tube diameter, mounting interface and wheel-axis details still require LF-J7-60-specific drawing or product-image confirmation.

Questions to Resolve Before Ordering LF-J7-60

Production Visibility for OEM and Distributor Buyers

Wheel-Equipped Trailer-Front Support with a 220 × 65 mm Ground-Contact Envelope

LF-J7-60 belongs to GOODIN’s wheel-equipped Boat Trailer Jack family and should be matched to the real vertical load at the support position, intended ground surface and the packaging required by its larger wheel.

Its 600 lb published capacity is one part of the application check; mounting, installed height and operating clearance still need exact model data.

Use the Full 220 × 65 mm Size When Reviewing Ground Contact and Clearance

A wider wheel can change contact pressure and obstacle behavior compared with smaller jockey-wheel formats, but actual rolling performance also depends on tyre construction, ground hardness, slope, wheel load and bearing/axle design.

Apply the 600 lb Rating to the Actual Jack-Position Load—not the Complete Trailer Weight

Determine the real vertical support load at the LF-J7-60 installation point. Do not assume the trailer GVWR, coupler tongue weight and jack-position load are identical values, and do not repurpose the 600 lb figure as a wheel rolling-load limit.

Plan Around the Larger Wheel Before Adding Other Tongue Hardware

The 220 × 65 mm wheel creates a known lower-envelope dimension even though the current bracket and handle geometry are not published. Check clearances around the coupler, winch, toolbox, wiring, safety equipment and any spare-wheel carrier in the final trailer layout.

GOODIN’s Utility Trailer Upgrade List provides a broader interface-planning approach for jacks, winches, toolboxes, lighting, spare carriers and tie-down hardware.

Inspect Plated Tubes and Wheel Hardware as Separate Wear Areas

The outer and inner tubes use different published zinc-finish descriptions. Wheel/rim condition, tube cleanliness, coating damage and the eventual confirmed axle/bearing arrangement should each be inspected according to the trailer’s maintenance environment.

Use the Larger Wheel Only When the Whole LF-J7-60 Package Fits

GOODIN’s current Boat Trailer Jack range includes several wheel and folding configurations. Select LF-J7-60 only after capacity, wheel envelope, mounting, height, storage clearance and exposure requirements are checked together.

A 220 × 65 mm rubber wheel does not turn LF-J7-60 into a powered mover or road-running wheel system. Use model-specific limits for any manual positioning requirement and keep people clear of slopes and uncontrolled trailer movement.

What to Send with the LF-J7-60 RFQ

Provide actual support load, trailer drawbar/frame drawing, required mounting method, required low/high support positions, intended surface, manual positioning requirement, environmental exposure, quantity and destination market.
