About the CAT 308 Mini Excavator
MWE offers OEM quality replacement tracks and undercarriage for the CAT 308 Mini Excavator from MWE, Camso, and Bridgestone. Our tracks feature continuous steel (joint-less) cords and are constructed from virgin (non-recycled) rubber, strong enough to handle even the most extreme applications. Our tracks are chunk and tear resistant thanks to natural rubber compounds that minimize vibration and offer a smoother ride, handling, and performance for your CAT 308.

Select from a wide range of tread patterns including Block, Multi-Bar, C-Pattern, and Blizzard that can provide both traction and flotation in a wide variety of applications. We have tracks for the CAT 308 in standard width, in addition to wide and narrow fitments. Choose a wider fitment to extend track life and minimize ground damage or use a narrow fitment for tight spaces.

Whatever your job requires, we have Rubber Tracks and Replacement Undercarriage Parts for your CAT 308 Mini Excavator at a savings nearly 50% less than dealer pricing.
