Tekno's customer interaction seems to be very good. The quality is excellent from what I hear. This alone for me is an easy choice for a second truck! Let's see some pics!
Totally fine to use the old shims. All of our other vehicles use them currently and we're happy with them. We just want to keep improving the products.
I assume the truggy diffs are different than the buggy diffs?
The diff internals are identical to all of our other vehicles except for the new shim. The truggy ring and pinion gears are specific to the truggies however.
