Upgrades are crucial for completing each of the levels and getting the best times to beat your friends. You can upgrade your truck in 4 different ways: Speed, Grip, Stability and Tilt.

Each upgrade affects the truck differently:

  • Speed - Improves power and speed
  • Grip - Better tires to climb hills with
  • Stability - Lowers the centre of gravity so your truck will be less likely to flip
  • Tilt - How fast you can rotate your truck in the air

These attributes can typically be upgraded 10 times each in total, once all of them have been upgraded to the maximum of 10 you'll no longer be able to collect Truck Coins for that truck and will be offered the choice to 'Custom Import' your truck.
