ONYUOKU 308287 Fifth Wheel Quick Release Pull Pins — 2-Pack 3/8" Zinc-Plated Spring-Loaded Replacement for Landing Gear

These ONYUOKU 308287 quick-release pull pins are a two-piece replacement set that lets you raise and lower fifth-wheel landing gear quickly and securely with a standard 3/8" pin diameter.

Designed as a direct-fit replacement for LC308287, this pair of heavy-duty quick release pull pins works with most fifth-wheel RV landing gear jacks that accept a 3/8" pin (fits 7/16" hole) and 2-1/4" square tube legs. Constructed from zinc-plated steel and supplied with bolt-on mounting brackets and hardware, the set upgrades your landing gear with a spring-loaded, stay-attached pin so adjustments are faster and less fiddly.

How do these pull pins speed up landing gear adjustments?

The spring-loaded design keeps the pin attached to the jack while allowing you to pull it out and change leg height quickly. Rather than searching for a loose pin or using tools, you pull the captive pin to unlock the leg, move the tube to the desired position, and release the pin to lock it in place.

• Spring-loaded captive pin stays attached to the jack for immediate use.
• Standard 3/8" diameter pin fits common 7/16" holes for broad compatibility.
• Bolt-on brackets and hardware let you retrofit without welding.
• Designed to fit 2-1/4" square landing gear legs used on many fifth wheels.

Will these replace my existing LC308287 parts directly?

Yes — ONYUOKU manufactures these pins to match OE specifications so they bolt directly in place of part number LC308287 without modification. The kit includes the necessary mounting brackets and fasteners for a straightforward swap.

• Direct-fit replacement for LC308287 — no drilling or welding required.
• Hardware included for a complete bolt-on installation.
• Pack of two pins covers both front landing gear jacks or provides a spare.

What materials and protections keep these pins durable outside?

• High-strength steel construction for long service life.

• Sturdy spring mechanism designed for repeated cycling under load.
• Quality control to meet OE fitment and performance standards.
