8000 lb Zinc-Plated Sidewind Trailer Jack | LF972B-701513

Authoritative LF972B-701513 Product Data

The supplied capacity field is not split into lift and support ratings; this page therefore keeps the neutral 8,000 lb capacity wording.

Outer, Mid and Inner Tubes Share the Same Published Finish

Verified LF972B tube-stage detail.

The source separately identifies the outer tube, mid tube and inner tube as zinc plated. This is stronger product information than the vague phrase “corrosion resistant” because it tells a buyer which visible telescoping stages receive the specified finish.

It still does not define coating thickness, passivation, sealing or a salt-spray acceptance value. Those requirements belong in the RFQ when the service environment makes them important.

Reserve Lateral Crank Clearance Around an 8,000 lb Manual Jack

The sidewind handle moves the operating envelope to the side of the jack body. Trailer frame members, toolboxes, deck structure and other fixed hardware should be checked through the full crank rotation.

Sidewind operation is a verified feature; gear ratio, handle radius and internal gear dimensions are not supplied and are not invented.

Use the Published 13–28 in Height Geometry as a Fit Check

LF972B-701513 publishes 15 in of travel, 13 in bracket height and 28 in extended height. Those values should be compared using GOODIN's own measurement reference.

Inspect Plated Sliding Surfaces and High-Contact Areas as Part of OEM Approval

For bulk sourcing, the useful finish discussion is not simply whether the jack “looks galvanized.” The controlling product language is zinc plated outer, mid and inner tubes.

Where corrosion performance is contractual, specify the required coating process, acceptance test and service environment separately rather than assuming a generic marine rating.

Six Checks Before Approving LF972B-701513

Questions Specific to LF972B-701513

Production Visibility for OEM and Distributor Buyers

Confirm Load, Height, Mount and Plating Requirements Together

Send GOODIN the expected jack-position load, trailer/frame drawing, mounting requirements, required working heights, sidewind clearance, corrosion environment, plating acceptance requirement, quantity and destination market. Non-standard programs can also review customized trailer jack options.

Higher-Capacity Manual Trailer Support with a Compact 13–28 in Published Height Window

LF972B-701513 is intended for compatible trailer applications that require an 8,000 lb-capacity manual sidewind jack and a 15 in adjustment stroke.

Application fit should be determined from actual vertical load, model-specific mounting geometry, required height, sidewind clearance, ground support and environmental exposure.

Treat 8,000 lb as the Published Jack Capacity—not Trailer GVWR

Select the jack against the actual vertical load acting through the jack position and verify the trailer-side structure independently. The source does not define a separate lifting versus stationary-support rating.

Confirm the 13 in Bracket Height, 15 in Travel and 28 in Extended Height Together

These three values create the published working-height geometry, but final replacement or OEM fit depends on using the same measurement reference shown in the current LF972B drawing.

Reserve a Real Lateral Crank Envelope

The sidewind handle must remain usable after bodywork, deck structure, toolboxes or other permanent hardware are installed. A capacity match alone does not guarantee operating access.

Translate “Zinc Plated” into a Project-Specific Corrosion Requirement When Needed

All three named tube stages are specified as zinc plated. That is useful for applications where exposed sliding tube finish matters, but it does not automatically establish marine-grade performance.

Do Not Treat LF971 or LF972 Sibling Geometry as LF972B Documentation

The supplied LF972B summary does not publish mounting type, hole spacing, tube dimensions, pin geometry or attachment method.

Those details should come from the current LF972B-701513 drawing or verified model-specific product images before an OEM or replacement application is approved.

Do not infer a drop leg from the three-tube finish description alone. A drop-leg mechanism, locking pin, extra coarse adjustment range or swivel mount should be published only after LF972B-specific verification.

Information to Send Before Approval

Provide actual jack-position load, trailer/frame drawing, required mounting method, coupling/support heights, sidewind clearance, ground-contact requirements, corrosion environment, requested plating specification, quantity and destination market.
