The 2017 Ultimate Callout Challenge (UCC) and Diesel Performance Industry Expo (DPIExpo) take place April 21-23 in Indianapolis, Ind. A nationwide “callout” to owners and builders of some of the toughest diesel-powered trucks in the country, UCC entrants compete against each other in three events: dyno, sled pull and drag race, with winners crowned in each event. AMSOIL-sponsored diesel builder Lavon Miller of Firepunk Diesel won the UCC championship last year and will be looking to defend his crown.

AMSOIL is the Exclusive Official Oil of the Ultimate Callout Challenge.
