Description
Upgrade Your Manual Trailer Jack with Drill-Powered Operation This trailer jack drill adapter is designed for compatible manual trailer jacks with a 1 inch drive shaft, helping you raise and lower your jack faster during hitching, unhitching, leveling, and trailer adjustment. One-Piece Design Unlike multi-piece socket adapter setups that rely on separate bits, square drives, and sockets, this one-piece adapter connects directly from the drill chuck to the trailer jack drive shaft. Fewer connection points help reduce wobble, looseness, and power loss under load. 4140-Grade Cr-Mo Alloy Steel Made from 42CrMo / 4140-grade chromium-molybdenum alloy steel, a material commonly used for high-load shafts and mechanical parts. Typical composition includes 0.38-0.45% carbon, 0.90-1.20% chromium, and 0.15-0.30% molybdenum. Black phosphate finish helps resist surface corrosion. Standard Drill Chuck Compatible The 0.35 inch hex shank fits standard 3/8 inch and 1/2 inch drill chucks. It is thicker than common 1/4 inch quick-change bits and is not designed for 1/4 inch quick-change impact drivers. Dimensions Fits: 1 inch jack drive shaft Sleeve inner diameter: 1.02 inch Sleeve outer diameter: 1.26 inch Sleeve height: 2.76 inch Pin hole diameter: 0.24 inch Pin hole spacing: 0.79 inch center to center Hex shank across flats: 0.35 inch Hex shank length: 0.98 inch Important Use Note Use with standard drill chucks only. Use low-speed, high-torque drill mode. Do not use with impact drivers, impact wrenches, or hammer mode. Impact tools create shock loads that may twist the shank, damage the retaining holes, or damage the trailer jack drive shaft. Keep the drill aligned with the jack shaft and stop immediately if the jack binds, tilts, or requires excessive force.
One-Piece Design: Unlike separate socket adapter bit setups, this one-piece adapter connects the drill directly to the jack drive shaft, reducing loose connection points, wobble, and power loss under load.
4140-Grade Cr-Mo Alloy Steel: Made from 42CrMo / 4140-grade chromium-molybdenum alloy steel, commonly used for high-load shafts and mechanical parts. Black phosphate finish helps resist surface corrosion.
Turns Manual Cranking into Drill-Powered Lifting: Use this trailer jack drill adapter to raise or lower compatible manual trailer jacks with a standard cordless drill. Ideal for hitching, unhitching, leveling, and adjusting RV, camper, boat, utility, and cargo trailers with 1 inch jack drive shafts.
Use Low-Speed Drill Mode Only: Use with a standard drill driver in low-speed, high-torque mode. Keep the drill aligned with the jack shaft and stop immediately if the jack binds, tilts, or requires excessive force.
Not for Impact Drivers or Impact Wrenches: Do not use with 1/4 inch quick-change impact drivers, impact wrenches, or hammer modes. Impact tools create shock loads that can twist the shank, damage the retaining holes, or tear up the trailer jack drive shaft.
