Heavy-duty fully automatic leveling system for Class A gas and Class 8 motorhomes (Ford F53, Chevy Kodiak 5500, Freightliner M2 and similar — under 24,000 lbs GVWR). Four independent quad pump units — one per corner — deliver nearly 4× the pump life of central pump systems. One-touch auto-level and one-touch auto-retract. 17,000 lb per cylinder, 18" stroke. 100 sq in Bigfoot pads. 240 lbs complete. Made in USA. Weld-on installation.
Class A gas motorhomes and Class 8 coaches in the 19,000–24,000 lb GVWR range represent some of the largest, heaviest units on the road — and their leveling systems need to match. The Bigfoot AKQ-8A1 is Quadra Manufacturing's answer for this chassis category: a quad pump automatic leveling system with individual hydraulic power units at each of the four corners, delivering both the lifting capacity and the long-term reliability that heavy coaches demand.
The quad pump architecture is the AKQ-8A1's defining advantage over central pump systems. Because each cylinder has its own dedicated marine-grade pump and motor, every pump runs only 25% as often as a single central pump would — cycling only when its own corner jack is in operation. Fewer cycles means dramatically less wear, and Bigfoot's own data puts quad pump longevity at nearly four times that of central pump alternatives. Each pump unit is wrapped in a weatherproof steel housing designed to mount outside the coach, preserving every inch of interior storage space. Four powder-coated cylinders — each rated at 17,000 lbs with 18" of stroke, machined at Quadra's White Pigeon, Michigan facility, hand-assembled, and 100% leak tested — carry a lifetime warranty. Press one button to level, press one button to retract. The all-up safety alarm prevents driving off with any cylinder extended. Manual individual control of each jack is available for fine-tuning or severely uneven terrain. The 100 square inch Bigfoot ground pads provide stable contact on soft or uneven surfaces. At 240 lbs complete with all components and hardware, the AKQ-8A1 is the definitive automatic leveling solution for Class A gas and Class 8 motorhome owners who want decades of reliable service. Built entirely in America.
One independent pump per corner — each runs only 25% of the time, delivering nearly 4× the service life of central pump systems
Press once to fully level, press once to fully retract — complete automation with no user monitoring or adjustment required
Heavy-duty cylinders rated for the largest Class A gas and Class 8 coaches — more capacity and longer stroke than the lighter AKC-8A1
All cylinders machined in-house at Quadra's Michigan facility, hand-assembled, and 100% leak tested — backed by a lifetime warranty
Most RV leveling systems use a single central pump to power all four jacks. The AKQ-8A1 takes a fundamentally different approach — four independent pump units, one dedicated to each corner jack. The math on pump life: A central pump runs every time any jack operates — 100% of the total operating time across all four corners. Each quad pump runs only when its own corner jack is in use — approximately 25% of the total operating time. With equal usage across all four corners, each quad pump accumulates roughly one-quarter the cycles of a central pump. Bigfoot quantifies this as nearly 4× the pump life. No single point of failure: If a central pump fails, all four jacks are inoperable. If one quad pump requires service, the other three corners still function. This redundancy matters when you're parked at a remote campsite or mid-trip far from service. Why it matters more for heavy coaches: Heavier Class A gas and Class 8 coaches put more load on each cylinder and require more operating time to reach level. The quad pump advantage compounds at higher GVWR — exactly the application the AKQ-8A1 is built for.
