ONYUOKU 308287 Fifth Wheel Quick Release Pull Pins - 2 PCS 3/8" Spring‑Loaded Zinc‑Plated Replacement for 2-1/4" Landing Gear

These ONYUOKU 308287 quick release pull pins are a heavy‑duty, bolt‑on replacement set that lets you raise and lower fifth wheel landing gear quickly and securely.

Whether you’re servicing an older fifth wheel or upgrading the jack hardware for smoother hookups, these two replacement pull pins match OE dimensions and fit standard 3/8" pins and 7/16" holes in 2‑1/4" square tube legs. Each kit includes spring‑loaded pins, mounting brackets, and hardware so you can install them without welding or modifications. The zinc‑plated steel construction helps resist rust while the spring mechanism keeps the pin captured so it won’t get lost during travel.

How do these pull pins make adjusting landing gear faster?

The spring‑loaded design keeps each pin attached to the jack, so you don’t need to fumble with loose fasteners when raising or lowering legs. A simple pull releases the locking mechanism, enabling quick height changes and faster hookup or stabilizing of your trailer. Because they match OE size LC308287, they drop in and work with existing holes and brackets.

• Spring‑loaded pin stays captive to prevent loss
• Standard 3/8" diameter fits 7/16" holes
• Works with 2‑1/4" square tube landing gear legs
• Two pins per kit for both sides of the jack

Will these pins fit my fifth wheel landing gear?

These pins are manufactured to OE specifications to directly replace part LC308287 and the listed dimensions — 3/8" pin diameter for 7/16" holes and compatibility with 2‑1/4" square tube legs. They are designed for common RV and trailer landing gear jacks, but you should confirm your jack hole and tube size before ordering.

• OE replaceable design — direct substitute for LC308287
• Intended for standard jack setups on campers and motorhomes
• Confirm hole diameter and tube size for compatibility

How difficult is installation and what tools are needed?

Installation is a bolt‑on process requiring no welding and can be completed with basic hand tools. The kit supplies mounting brackets and hardware; typical installation involves removing the old pin, positioning the bracket, and securing the new spring‑loaded pin assembly with the provided bolts. Allow about 20–40 minutes per side for a straightforward swap.

• No welding — uses supplied brackets and bolts
• Requires common tools: wrenches, sockets, possibly a drill for alignment
• Typical install time: 20–40 minutes per side
• Instructions: align bracket, insert pin, tighten hardware

How durable are these replacement pins for road and weather exposure?

Manufactured from high‑strength steel with a bright zinc‑plated finish, the ONYUOKU pull pins are built to resist corrosion and stand up to frequent use. The spring and pin materials are selected to handle load cycles typical of landing gear operation without deforming, while the finish slows rust in wet or salty environments.

• Zinc plating reduces surface rust and corrosion
• Heavy‑duty steel construction for repeated use
• Spring design engineered to stay engaged under vibration
• Backed by a 36‑month warranty and 30‑day return policy
