The Last Trailer Jack You'll Ever Need
Introducing two trailer jack models to withstand the harshest marine environments
Deluxe Trailer Jack
Sierra’s Trailer Jack Deluxe features a 1,500 lbs. load capacity and a 10-inch travel distance. Designed to fit tongues up to 3 inches x 5 inches, the Deluxe quickly pivots into a horizontal position and is ideal for hauling boats, snowmobiles, and smaller sports craft. The zinc-plated undercoat with a tough black textured overcoat provides maximum protection from corrosion. A durable crank handle and a heavy-duty 6-inch wheel make managing your trailer load easy and comfortable.
Deluxe Plus Trailer Jack
Sierra’s Trailer Jack Deluxe Plus features the same 1,500 lbs. load capacity but delivers a larger 12-inch travel distance, an 8 inch heavy-duty wheel, and a wheel caster that swivels independently from the inner post. Designed to fit tongues up to 3 inches x 5 inches, the Deluxe Plus quickly pivots into a horizontal position and is ideal for hauling boats, snowmobiles, and smaller sports craft. The zinc-plated undercoat with a tough black textured overcoat provides maximum protection from corrosion. A durable crank handle and an extended sleeved pull pin make managing your trailer load easy and comfortable.
