4WD Upgrades for Ford Vans

For the Ford van’s front end, it is necessary for to redesign the 4×4 front axle. This upgrade consists of a new casting, larger knuckles, hub and F550 rotors. Ford also beefed-up the calipers. The calipers, rotors and ABS sensors are Ford factory parts, making this system easier to service.

These changes are comparable to a $2,000 upgrade.

However, the redesign causes one issue:
with larger brake rotor, the factory 16″ wheels will not fit. Sportsmobile 4WDs require 17″ wheels available through Sportsmobile.
