Industry-first patented bolt-on automatic leveling for 2008+ Ford E-350 chassis. No welding required for front cylinders. 8,000 lb per jack, 13" stroke, 90–120 second auto-leveling, lifetime cylinder warranty.
The Bigfoot AKC-E3502 is the industry's first bolt-on hydraulic automatic leveling system for Ford E-350 chassis Class C motorhomes—a patented design that eliminates the welding requirement that has long been the biggest obstacle to adding a professional-grade leveling system to an E-Series coach. The front cylinders mount completely bolt-on with no drilling or welding to the front frame, while the rear cylinders offer the flexibility of drilling or welding to suit your chassis and installation preference. The result is the fastest, cleanest leveling system installation available for the E-350 platform, with no frame modification required up front.
Designed for 2008 and newer Ford E-350 chassis—and also compatible with older or lower-riding Ford E-450 chassis—the AKC-E3502 delivers one-touch automatic leveling in just 90 to 120 seconds through a single central marine-grade hydraulic power unit. Four powder-coated cylinders machined in-house at Quadra's White Pigeon, Michigan facility deliver 8,000 lbs of lifting capacity each with 13" of stroke, all backed by a lifetime cylinder warranty. The entire system weighs just 150 lbs and ships complete with everything needed for installation. Whether you're a first-time hydraulic leveling buyer drawn to the no-weld front installation or an experienced installer who appreciates the precision of a patented bracket system, the AKC-E3502 sets the standard for Ford E-350 leveling upgrades.

Primary Application: • 2008 and Newer Ford E-350 Chassis (Full Bolt-On Front, Drill/Weld Rear) • Class C Motorhomes Built on Ford E-350 Chassis Also Compatible: • Older or Lower-Riding Ford E-450 Chassis (check frame height) Older Models (Pre-2008 E-350): Additional drilling or modifications may be required. For pre-2008 E-350 chassis, contact us at 1-866-332-7881 to confirm fitment before ordering. Frame Height Check — Required for Older Vehicles: For vehicles 5 years old or older, measure frame clearance before ordering. Underneath the cab on the driver's side, locate the control arm mounting bracket for the front axle, then measure from the bottom of the vehicle frame to the ground (on a level surface). If this measurement is below 15", the E-350 part numbers with shorter front cylinders are correct for your application. If this step is skipped, cylinders may need to be swapped during installation (additional fee applies). Two-Stage Air Suspension Note: Check the rear frame for two-stage air suspension. These chassis may require additional drilling or different brackets for rear cylinder mounting.

Both systems deliver identical automatic leveling performance on the same Ford E-350 chassis. The only difference is how the front brackets attach to the frame:
For most Ford E-350 Class C owners, the AKC-E3502 bolt-on system is the clear choice — it delivers identical performance with a significantly simpler front-end installation. The AKC-E3501 weld-on may be preferred by owners who already have welding access and want a fully welded bracket on all four corners.
Bigfoot offers multiple systems for the Ford E-350 chassis across different operation styles. All use the same 8,000 lb cylinder platform:
