TRXF21HE - Heavy 72g Modular Brass Outer Portal Drive Housing Tra Trx-4

Hot Racing heavy brass modular outer portal drive housings for the front of the TRA TRX-4 crawler. Adds weight to the TRA TRX-4 crawler where it needs it - down low. Adds around 72g per hub to lower the vehicle's center of gravity, increase its stability, improve climbing, reduce the chance for flipping backwards, and make it an overall more capable crawler. The modular design allows the addition of Hot Raqcing TRXF21HWR (47g Brass Inner Modular Weight) and/or TRXF21HWF (21g Brass Outer Modular Weight) to be added to further tune the vehicle's performance.
