Plastic vs. Aluminum, Weak vs. Strong, Non-Rebuildable vs. Rebuildable; the battle outcome between the Standard Plastic T-Nut and MIP’s all New Aluminum Machined T-Nut! MIP’s all new 7075-T6 machined aluminum T-Nut is completely rebuildable by simply replacing the small nylon inserts. These high quality nylon inserts increase the screws break away force by 20%, meaning that the diff screw will stay in its desired position much longer and increase the consistency of your differential over time. The aluminum design also increases sheer strength of the “T” by a whopping 40%! If you’re looking for consistency, strength, and longevity out of your differentials, MIP has the answer. Fits Team Associated 4th and 5th generation ball differentials and MIP AE/TLR ball differentials.
