HVJ Trailer Jack Drill Adapter for 1-inch Jack Shaft — Stainless Steel, Drill & Ratchet Compatible

HVJ's Trailer Jack Drill Adapter converts a 1" jack drive shaft into a drill- or ratchet-operated jack so you can raise and lower trailers quickly and without hand cranking.

This stainless-steel adapter kit fits 1-inch jack drive shafts and includes sockets, clevis pins, cotter pins, bolts, nyloc nuts and gaskets so you have the parts needed for a secure installation. Designed for RVs, utility trailers, dump trailers and construction trailers, the adapter lets you use an electric drill or a 1/2" ratchet to operate the jack, reducing time and physical strain when hitching, leveling, or servicing your trailer.

How does the HVJ adapter let me use a drill instead of hand-cranking?

The kit supplies a 1/2" square drive socket adapter that slips over the jack shaft and accepts a drill chuck or standard ratchet drive. Once installed, you simply attach your power drill or ratchet to the adapter and rotate to raise or lower the jack—no manual cranking needed.

• Includes 1/2" square drive socket adapter for drill or ratchet compatibility
• Clevis pin and R-type cotter pins lock the adapter to the jack shaft securely
• Bolts and nyloc nuts provide a vibration-resistant fastened connection
• Gaskets protect mating surfaces for a snug, long-lasting fit

Will this kit hold up outdoors and resist corrosion?

Yes—components are made from high-grade stainless steel chosen for wear and corrosion resistance in outdoor conditions. The durable construction helps prevent rust and maintains strength where jacks see moisture, road salt, and heavy loading.

• Stainless-steel parts for extended outdoor durability
• High hardness resists deformation under load
• Gaskets reduce metal-on-metal wear and help seal joints
• Hardware includes nyloc nuts to resist loosening from vibration

What trailers and jack types is the adapter compatible with?

This HVJ adapter is engineered specifically for jacks with a 1" drive shaft and works across a wide variety of trailers. It’s commonly used on RVs, utility and landscape trailers, dump trailers, and many construction trailers that use the same shaft dimension.

• Designed for 1" jack drive shafts—confirm your shaft diameter before buying
• Commonly fits RVs, utility, dump, and construction trailers
• Works with both electric drills and 1/2" ratchet tools for flexibility
• Ideal when frequent hitching or leveling makes manual cranking impractical

How straightforward is installation and what’s included?

Installation is intended to be simple: slide the adapter onto the 1" shaft, secure with the provided clevis and cotter pins, and fasten bolts and nyloc nuts as required. The kit bundles the parts you need to avoid sourcing hardware separately.

• Kit contents: 1 adapter, 2 drive socket adapters, 2 clevis pins
• Also includes 4 R-type hairpin cotter pins, 2 bolts, and 2 nyloc nuts
• Four gaskets included to ensure tight mating and reduce wear
• Quick hookup—no special tooling beyond a drill or 1/2" ratchet
