The YouTube Channel *Driving Line* has been providing a regular "Ride of the Week." This week the feature vehicle is [former Discovery Channel series *Fast N Loud* star Aaron Kaufman](<https://www.thedrive.com/article/9584/aaron-kaufmans-pikes-peak-ford-falcon-is-up-for-auction>)'s Ultra4 Cummins Scout.

Kaufman left the *Fast N Loud* series to star in his own Discovery Channel series, *Shifting Gears*. Kaufman's build started life as a 1971 International Scout 800 Camanche and was fitted with a slew of upgrades by his shop, Arclight Fabrication, to become a race-legal Ultra4 rig.

The car features a custom three-link suspension system, KING coilovers with hydraulic bump stops, Currie front and rear axles, a custom interior, and a 4BT Cummins engine with Borg Warner turbos.
