Ford Ranger 4-Corner Full-Air Kit (inc. controls)

For Ford Ranger owners who demand the ultimate in ride quality, capability and versatility, On Air Suspension's 4-Corner Full Air Suspension Kit is the definitive upgrade. Replacing both front and rear suspension with a fully engineered air system, this kit transforms the Ranger from a capable pickup into a truly adjustable, all-conditions vehicle — without sacrificing the toughness the Ranger is known for.
 
The Complete Solution
Where the rear-only kit addresses load carrying and towing, the 4-corner kit goes further — delivering adjustable ride height at all four corners with independent control, automatic levelling and a significant improvement in on-road ride quality. The front conversion uses bespoke strut assemblies engineered specifically for the Ranger's front suspension geometry.
 
What's Included?
The 4-corner kit contains everything in the rear kit plus the complete front conversion:
Front strut assemblies (left and right) — bespoke to Ranger geometry
Open-ended front air springs matched to Ranger front suspension travel
Front height sensors with brackets
Steering wedge adjuster — Ranger specific
Front tri-bracket assembly
4-Corner ECU (Intelliride) with PC programming tool
4-Corner wiring harness refined for pickups
12V compressor with dryer
3-gallon air tank (2 port)
All Ranger-specific brackets, fixings and hardware
 
Benefits
Full 4-corner height control — adjust ride height front and rear independently
Access height — lower the vehicle for easy entry and exit
Off-road clearance — raise beyond standard ride height when terrain demands
Automatic load levelling — constant ride height under any load at all four corners
Transformed on-road ride — air springs significantly improve comfort over standard coils
Towing stability — maintain level attitude with heavy trailer attached
 
Designed and Built in the UK
Like all On Air Suspension kits, the Ranger 4-corner system is engineered from the ground up by our in-house team in Ongar, Essex. The front strut assemblies, subframe components and control system are all developed specifically for the Ranger chassis — not off-the-shelf parts adapted to fit. The Intelliride 4-corner ECU is configured and calibrated for the Ranger's suspension travel and geometry.
