Sizing, compatibility, and what it fits

Designed for DO35 tongues, this kit uses a 7/8" shaft with 22 UNF threads (approximately 22 mm). It’s specifically intended to match DO35 hitch requirements and is compatible with older DO35 tongue variants, making it an ideal replacement or spare for established setups. Before use, confirm your tow tongue accepts a 7/8" - 22 UNF shaft to ensure a secure fit.

Who benefits most

• Owners with a second tow vehicle who want a ready, boxed kit for quick attachment on the go
• Anyone replacing a worn or lost DO35 pin to restore hitching reliability
• Seasoned tow enthusiasts planning trips where fast, tool-assisted pin removal is a plus

Why this kit stands out

• All-in-one boxed set — avoid hunting for a pin, cover, and tool separately
• Precise 7/8" (22 mm) UNF shaft optimized for DO35 tongues, balancing secure engagement with straightforward removal
• Boxed packaging protects components during storage and transport, reducing the risk of misplacing parts

Practical tips for quick, trouble-free use

• Store the kit in the included box so you always have the pin, cover, and C-spanner ready for hitching and unhitching
• Before towing, verify the pin slides smoothly into the tongue and threads engage cleanly without cross-threading
• Use the C-spanner to install or remove the pin securely, then snap on the pin cover to shield the shaft from dirt
• If you’re unsure about fit, double-check the tongue’s diameter against the 7/8" shaft specification to prevent compatibility issues
