MOD Skinny Bone Puck System For The B74

From MOD:
The New NEW… What has Changed and Why?

Thank you for considering the all new MOD / MIP Puck System for the Team Associated B74 4wd buggy. The Puck system has been revered as one of the most essential upgrades for 13.5 4wd buggies and with the B64 puck system it took plenty of championships to back up the claim. But the B64 puck system wasn’t without its shortcomings mainly in the strength of the front and rear aluminum puck bones. On a hard front arm impact the Aluminum bones would tend to bend, needing replacement, that is the first of the short comings. The second of which came with the progression of increased traction track surfaces mainly turf and carpet, with the increased traction and hard landings on power the Front and Rear Aluminum bones would twist over time and eventually break. So we went to work and helped developed the all new MIP Skinny Bones! They are super light within 10% of the weight of the Aluminum counterpart but boast a 400% increase in torsional strength. So with this new system you are still able to reduce your rotational mass be confident in the longevity and integrity of the bones on all surfaces (DIRT / CARPET / TURF). The Center Bones are still aluminum as they do not see nearly the same type of load and no failures in the past on any surface so they were kept the same. Overall we have taken all into consideration in developing this all new system made 100% in the USA at MIP’s World Class Manufacturing Facility. Welcome to the new Bi-Metal / Skinny Bone Puck System, Enjoy!
