The United Pacific 31" heavy-duty chrome 5th wheel pin puller is a solid-steel J-hook tool designed to quickly and safely release fifth-wheel locking pins with a long shaft and wide 5-inch handle for improved leverage and less mess.

Built for truck drivers and fleet technicians, this single-unit United Pacific pin puller brings durable construction and ergonomic design to a simple but essential roadside task. Chrome-plated for corrosion resistance, the 3/8" diameter shaft and 31" length provide reach and control to free stubborn pins without kneeling in grease or straining your hands. It’s a compact addition to any toolbox that prioritizes efficiency, durability, and user comfort.

How does this tool make uncoupling a trailer easier?

The long steel shaft and 5" handle increase leverage so you can pull a locked fifth-wheel pin with less physical effort. Its J-hook end engages the pin securely to prevent slipping while you apply steady force, speeding routine trailer changes and reducing the chance of fumbling in tight spaces.

• 31" length provides extended reach behind the tractor frame
• 5" handle offers a comfortable two-handed grip for more torque
• J-hook end designed to grip standard fifth-wheel pin heads
• Chrome finish minimizes corrosion and eases cleaning

What are the construction and corrosion-resistance features?

Manufactured from solid steel, this pin puller resists bending under normal heavy-duty use and delivers long service life in demanding environments. The chrome plating protects the surface from rust and grime, helping the tool stay functional after repeated exposure to road salt, oil, and weather.

• Solid steel rod with 3/8" diameter for strength
• Chrome-plated surface for rust resistance and easy wipe-downs
• Robust handle welded or formed for secure attachment
• Available in 31" (this listing) and 36" lengths for different reach needs

Which pin style and sizes does this puller fit?

This United Pacific puller is offered with a J-hook end (this listing) that matches common fifth-wheel pin designs and provides secure engagement while pulling. The 3/8" shaft and hook geometry are sized for typical heavy-duty truck pins; check your rig’s pin shape to confirm compatibility before purchase.

• J-hook end for standard fifth-wheel pin heads
• 3/8" rod diameter suited to heavy-duty applications
• 31" reach for most tractor-clearance situations
• Sold individually; order multiple units if needed for fleet use

How should I use and maintain the pin puller for best results?

Use the tool by seating the J-hook under the pin head, then apply steady pull using the wide handle to disengage the lock. After use, wipe off grease and store in a dry toolbox; occasional light lubrication of the handle joint (if present) and a quick chrome-friendly cleaner will keep the tool operating smoothly.

• Seat hook fully beneath pin head before pulling
• Use two hands on the 5" handle for controlled leverage
• Wipe clean and inspect for bends or wear after heavy use
• Replace if the hook or shaft shows deformation or cracks
