T1 Race Development GT1R CNC Billet Rear Differential Cover – Nissan GT-R R35


Additional information

Build it, break it, make it stronger, it’s a theme that tends to go with pushing boundaries. The fact that the GR6 transmission is keeping up with 1500whp builds is mind boggling. The fact that it’s keeping up with 2500whp builds is ludicrous. Little by little new limits are found and new solutions are born. ShepTrans took the leap and had Wavetrac build an upgraded differential when failures started happening in that department. When the stock diff fails it almost always breaks the diff cover as well. We believe the stock cast diff cover flexes and leads to premature differential failure. The combination of the ShepTrans Wavetrac diff and our diff cover should make things just about bulletproof!
