A space-saving air shift cover maximizes clearance under the truck. The series is rated for intermittent torque in the 301-400 lb-ft range and supports continuous operation with a 30% de-rating. Compatible transmission manufacturers include Eaton Fuller, Volvo/Mack, and Daimler/Detroit. The deep mount housing option accommodates Mack transmission applications.
