Choosing F100 Ride Height: Street, Sport, or Air?
If you're building a classic Ford truck, ride height is one of the first big decisions you'll make — and it's one of the easiest to get wrong. Spencer walks you through all three FF Chassis options for your F100: Street, Sport, and Air. Same engineering, same independent front suspension, three completely different stances.
In this video, we have all three chassis side by side so you can see exactly what each one looks like and what it'll do for your build. Spencer breaks down the differences in C-notch height, spindles, suspension geometry, and what kind of fabrication each chassis requires from your sheet metal.
THE THREE FF CHASSIS RIDE HEIGHTS:
FF STREET CHASSIS
Sits 1 to 2 inches lower than stock. Bolts in with zero modifications to your bed, wheel tubs, inner fenders, or firewall. Runs on coilovers with our custom non-drop spindle. The smart choice if you want a clean, level stance without the fabrication cost.
FF SPORT CHASSIS
Drops you 4 to 6 inches lower than stock for that aggressive coilover stance. As low as you can go before you're forced into airbags. Requires fabrication — raised bed, widened wheel tubs, possible inner fender mods. Runs on a Wilwood Pro spindle. The pick if you want a sporty, show-ready truck on coils.
FF AIR CHASSIS
Full airbag setup with the biggest C-notch of the three. Airs up to sport ride height and lays frame on the running boards — within an eighth of an inch of the ground. Comes with a Watts link rear suspension for flex and lowering. The pick if you want maximum drop, plush highway ride, and that wow factor at shows.
Spencer also gets into the stuff most people don't think about until it's too late: axle widths, wheel and tire decisions, what's welded versus what's bolt-in for future modularity, and why we engineer these chassis to be sold as complete systems.
