Professional hydraulic landing gear with 12,000 lb capacity and emergency manual override. One pump, two-cylinder slaved system for horse, cargo, and equipment trailers. Made in America.
Say goodbye to slow, unreliable electric jacks and manual hand cranking. The Bigfoot SQI24-2PTSMO landing gear system delivers professional-grade hydraulic power that lifts up to four times faster than electric jacks while using less battery power. This dual-point slaved system operates both jacks simultaneously from a single marine-grade pump, ensuring balanced lifting every time. With 12,000 lb capacity and 24 inches of travel, this system handles heavy horse trailers, cargo trailers, equipment haulers, and gooseneck applications with ease.
The manual override feature sets this system apart from standard hydraulic jacks. If you ever lose power or experience a dead battery, simply use the included hex drive adapter with any household drill or hand ratchet to operate the system mechanically. This fail-safe backup ensures you're never stranded, making it the perfect choice for remote locations or emergency situations. Manufactured by Quadra Manufacturing in White Pigeon, Michigan, every component is built to last with heavy-duty steel construction, tube-in-tube cylinder design, and weatherproof IP65-rated controls.

Single Pump, Dual Cylinder Design: Unlike dual-pump systems where each jack operates independently, the SQI24-2PTSMO uses a "slaved" configuration with one central pump controlling both cylinders simultaneously. This design ensures perfectly synchronized lifting with both jacks moving at identical speeds, preventing trailer twisting or frame stress during operation. Operational Advantages: • Simplified wiring with single control box • Reduced electrical draw (one pump vs two) • Automatic balanced lifting (no manual adjustment needed) • Fewer components to maintain • Lower overall system cost The pump can be mounted directly to the front of the jack (standard) or remotely mounted anywhere on your trailer frame for better weight distribution or compartment clearance. All hydraulic lines, fittings, and wiring come pre-configured for straightforward installation.
Hydraulic Components: • Two SQI24 Square Leg Jack Cylinders (35" retracted, 24" stroke) • One Marine-Grade Pump/Motor Assembly with Manual Override • Hydraulic Hoses (Universal Length) • JIC Hydraulic Fittings • Two Large Swivel Foot Pads Electrical Components: • Weatherproof Control Box (IP65 Rated) with Key Lock • Extended Wire Harness for Flexible Placement • 120-Amp In-Line Circuit Breaker • Complete Wiring Kit with Connectors Manual Override System: • Hex Drive Adapter (1/4" Hex) • Manual Operation Instructions Mounting Hardware: • Universal Adjustable Mounting Brackets (Set of 2) • Installation Hardware Kit (Bolts, Nuts, Washers) NOT Included (Available Separately): • Dexron III Hydraulic Fluid • Cordless Drill or Hand Ratchet (for manual override operation)
Professional Installation Recommended: While this system uses universal mounting brackets and does not require welding, proper installation is critical for safe operation. Brackets must be securely fastened to trailer frame with adequate clearance for full jack extension and retraction. Frame Compatibility: Verify your trailer frame can accommodate the 4.5" x 4.5" square jack tubes and mounting bracket dimensions before ordering. Measure available space and ground clearance to ensure proper fit. Electrical Requirements: System operates on 12V DC trailer battery power. 120-amp breaker must be installed in-line between battery and pump assembly. Ensure battery is fully charged for reliable operation. Manual Override Operation: The hex drive adapter allows emergency operation using a cordless drill (low speed setting) or hand ratchet with 1/4" hex socket. Practice manual override operation before you need it in an emergency.Download the Bigfoot SQI24-2PTSMO Installation Manual
The slaved system is ideal for applications where you park on relatively level ground and need fast, synchronized lifting. For situations requiring frequent side-to-side leveling adjustments, consider the dual-pump SQI24-2DMO model with independent jack control.
Regular Maintenance Schedule: • Check hydraulic fluid level monthly - maintain proper fill line • Inspect hoses and fittings for leaks every 3 months • Clean jack cylinders and remove road debris before each use • Test manual override operation twice per year • Lubricate foot pad swivel points annually with marine-grade grease • Verify mounting bracket bolts are tight at start of each season • Keep battery fully charged - weak batteries reduce pump performance Common Issues and Solutions: • Jacks Won't Extend: Check battery voltage (need 12.4V minimum), verify 120-amp breaker not tripped, inspect wire connections at pump • Slow Operation: Low battery charge is most common cause - recharge battery fully, also check for hydraulic fluid level • Hydraulic Leak: Tighten loose fittings carefully (do not overtighten), inspect hoses for cracks or abrasion damage • Jacks Don't Retract Fully: Check for obstructions preventing full travel, verify limit switch operation, inspect for bent cylinder tube • Manual Override Difficult to Turn: This is normal under heavy load - use drill on low speed for easier operation, or use longer hand ratchet for better leverage Hydraulic Fluid Specification: Use Dexron III automatic transmission fluid (ATF). Compatible alternatives include Dexron II, ATF+4, Mercon, or Mercon V. Do not overfill reservoir - maintain ¾" from top of fill line.
