28T/32T/70T Trailer Landing Gear for Semi-Trailers
Quick answer: choose 28T or 32T landing gear for mainstream semi-trailers that need dependable daily parking and loading support, and move to the 70T class when the trailer program is materially heavier or the support-leg demand is far above standard road-freight duty. This page is the right fit when you are choosing the trailer support legs themselves, not the king pin or fifth wheel coupling.

Trailer landing gear family: this Kales page covers 28T, 32T, and 70T landing gear options for semi-trailers, with interlinked support-leg structure for parking stability, loading support, and practical field service. It is built for buyers who need to match support-leg capacity to trailer class rather than buying one generic landing gear set for every chassis.
Engineering guidance from the Kales Vehicle parts team for buyers comparing landing gear sizes, tractor-trailer connection hardware, and heavy-duty trailer support components.

Family selection table
| Landing gear class | Best-fit trailer situation | Selection logic |
|---|---|---|
| 28T | Standard semi-trailer parking and loading support | Good entry point for mainstream export trailer programs |
| 32T | Heavier mainstream road-freight support demand | Extra margin for buyers who want a stronger support-leg class without moving to an extreme-duty setup |
| 70T | Special heavier-duty trailer support requirement | Used when the support-leg duty is materially above ordinary semi-trailer service |
Best Fit Operating Profile
This landing gear family is best suited to trailer builders, replacement-parts buyers, and fleet workshops that need reliable parked-trailer support matched to actual trailer weight class. It works well for standard road-freight trailers, export trailer assembly, and heavier-duty programs where the support legs must stay stable during loading, unloading, and uncoupled parking.
Best for
- Standard semi-trailers needing 28T or 32T support-leg replacement
- Heavier trailer programs that need a stronger 70T landing gear class
- Fleet rebuild workshops standardizing parked-trailer support hardware
- Export buyers who need route-matched landing gear specification rather than generic low-price sourcing
Not ideal for
- Buyers who actually need the king pin or tractor-side fifth wheel instead of landing gear
- Requests where trailer support class has not been matched to the chassis duty yet
- Applications that need axle or suspension replacement rather than front support legs
Why Buyers Choose This Landing Gear Family
- Clear size ladder: 28T, 32T, and 70T support classes make it easier to match landing gear to trailer duty.
- Stable fixed base design: thickened and widened side-plate structure improves standing stability during loading and unloading.
- Spline-connected universal flange: helps smoother operation and easier replacement in workshop service.
- Electroplated piston rod: better rust, wear, and corrosion resistance in humid or outdoor conditions.
- High-frequency quenching on critical parts: improves hardness and helps resist deformation under load.
- Family-range pricing: AggregateOffer fits a multi-capacity page better than pretending all landing gear options are one fixed SKU.
How This Landing Gear Family Should Be Evaluated
The right way to evaluate semi-trailer landing gear is to start with support duty rather than sticker price. Buyers should check trailer class, loading pattern, parked support requirement, corrosion exposure, and whether the fleet wants the easiest replacement path in local workshops. That is what separates a correct landing gear purchase from a support-leg set that looks cheap but fails early under real load cycles.
| Buyer situation | Best-fit Kales direction | Why |
|---|---|---|
| Mainstream road-freight semi-trailer | 28T or 32T landing gear | Better matched to everyday trailer parking and loading support duty |
| Heavier-duty trailer support demand | 70T landing gear | Provides the stronger support class for materially heavier applications |
| Buyer replacing trailer connection hardware | King pin or fifth wheel page | Landing gear supports the parked trailer; it does not lock tractor to trailer |
| Buyer rebuilding suspension or axle running gear | Suspension or axle page | Landing gear should be specified separately from running gear components |
Engineering and Serviceability Details
Why the fixed base matters so much
The fixed base is the stability foundation of the landing gear. Thickened and widened side plates, combined with precision welding, help the support legs stay more stable during loading, unloading, and longer parked-trailer service. Buyers who ignore base strength often end up with support legs that work acceptably at first but lose confidence under real yard conditions.
Why the universal flange and spline connection are practical features
The old product content is right to emphasize the universal flange and spline connection. That detail matters because smoother operation and easier replacement reduce downtime in service workshops. For fleets buying export parts, replaceability is often more important than cosmetic design claims.
Why piston rod treatment and quenching matter in the field
The electroplated piston rod helps resist rust, wear, and corrosion, especially when landing gear spends long periods outdoors or in humid transport environments. High-frequency quenching on critical components adds hardness and helps prevent deformation under repeated loading cycles. Those are real service-life controls, not brochure filler.
Why the page keeps an AggregateOffer structure
This is a family page with multiple support classes and configuration choices. Final pricing depends on whether the buyer needs 28T, 32T, or 70T landing gear and how the trailer program is specified. A range price is more accurate than pretending the whole family is one exact model.
Price and Procurement Guidance
Before asking for a quote, buyers should send trailer type, expected support duty, whether the trailer program is mainstream or heavier-duty, and any corrosion or route constraints that affect parts life. Kales can then match the correct 28T, 32T, or 70T landing gear class instead of quoting a generic support-leg set with the wrong duty margin.

Questions before ordering
What is the difference between 28T, 32T, and 70T landing gear?+
The difference is support-duty class. The 28T and 32T classes fit mainstream semi-trailer support needs, while the 70T class is for materially heavier support-leg demand.
Is landing gear the same as a king pin or fifth wheel?+
No. Landing gear supports the parked trailer. The king pin and fifth wheel are the tractor-trailer connection components.
Why does spline connection matter on the universal flange?+
It helps smoother operation and easier replacement, which reduces workshop service time and makes the landing gear more practical in field maintenance programs.
Why does this page use a price range instead of one fixed price?+
Because this is a landing gear family page covering 28T, 32T, and 70T options rather than one single stock model.
What information should I send before requesting a quote?+
Send the trailer type, expected support duty, whether the program is mainstream or heavier-duty, and any route or corrosion constraints that affect parts life.
Request Landing Gear Matching and Quote
If you need 28T, 32T, or 70T trailer landing gear, send your trailer type, support-duty requirement, and route profile. Kales can then match the correct landing gear class for your trailer build, fleet replacement plan, or export parts order.
