One-touch fully automatic leveling for Chevy 3500/4500 Class C motorhomes. Levels in 90–120 seconds. 8,000 lb per jack, 13" stroke, central pump design, lifetime cylinder warranty, 170 lbs complete.
The Bigfoot AGC-C4500 is a fully automatic central pump hydraulic leveling system designed specifically for Chevrolet 3500 and 4500 Class C motorhome chassis. In an RV segment where manual jacks and semi-automatic systems still dominate, the AGC-C4500 delivers true one-touch convenience: press the button and walk away — the system automatically levels your coach in 90 to 120 seconds without any further user input. Manual individual jack control remains available when you need to fine-tune or adjust for severely uneven sites, and the emergency retract button provides instant simultaneous retraction of all four jacks in critical situations.
A single central hydraulic power unit — an American-made marine pump and motor wrapped in weatherproof steel housing — powers all four cylinders and mounts outside the coach to preserve every cubic inch of interior storage. Four powder-coated 8,000 lb cylinders with 13" stroke are machined at Quadra's White Pigeon, Michigan facility, hand-assembled, and 100% leak tested before shipment with a lifetime warranty. The all-up safety feature signals visually and audibly if any cylinder is not fully retracted before driving, and 7 inch Bigfoot pads provide secure ground contact on soft or uneven surfaces. At 170 lbs complete with all necessary components and hardware, the AGC-C4500 is a chassis-specific automatic leveling solution for Chevy 3500/4500 Class C owners who want the convenience of full automation, built entirely in America.

Bigfoot offers both central pump and quad pump systems for various chassis. Here's how the AGC-C4500's central pump design compares:
The AGC-C4500's central pump design offers simpler installation and lighter weight. Quad pump systems offer longer pump life and no single point of failure, but are heavier and more complex to install. For the Chevy 3500/4500 chassis, the central pump is the standard configuration.
RV SnapPad BF-7 pads snap permanently onto your Bigfoot landing pads and stay attached during travel — no more placing and retrieving pads at every campsite. They protect asphalt and hard surfaces, prevent sinking on soft ground, and cut setup time to seconds.
