Custom Engines & Gearboxes

This mod greatly expands the powertrain options in the game: choose from over 20 gearboxes and retarders, ranging from 6-speed all the way up to 22-speed configurations, along with 30+ engines that unlock right at level 1. It allows you to fully customise your truck's drivetrain to suit your driving style, bypassing the lengthy unlock progression of the default engines and transmissions.
