Happy 4th of July from all of us at Maximum 4X4. 🇺🇸
-
We had the privilege of getting this local fire department's Ram 5500 dialed in before it heads into service.
-
This build received a suspension lift, upgraded rear leaf springs, FOX shocks front and rear, and a new set of running boards. This week we're dialing in the ride height before it's ready to hit the road protecting our community.
-
We appreciate everyone who serves and wish you all a safe and happy Independence Day.

Wrapped up the final suspension and steering details on this Power Wagon build.
-
We dialed in the ride height, adjusted the 4-link, and set the caster and pinion angles. We also built a new track bar and bracket to correct the steering geometry, then added a brace to the steering gearbox mount to help prevent flex and cracking.
-
It's the little details that make the difference between a truck that just looks good and one that drives the way it should.

This one rolled in with a completely failed factory air ride system and left without ever having to worry about that again.
-
We deleted the problematic factory air ride, installed a 3.5" Rough Country suspension lift, mounted a fresh set of 18" Mayhem Wheels, and wrapped them in BFGoodrich Tires KO3s.
-
No more air ride headaches.
