TA08R/Pro Alum. Diff.-Mount +0.8, chassis option part

These aluminum differential holders are a focused chassis upgrade for TA08R, TA08 PRO, TRF420X and TRF420 builds. The 2-piece set adds a 0.8 mm offset and gives the differential section a rigid mounting point, while the integrated notch works with belt tension adjustment for a more exact drivetrain setup. Under load, the aluminum construction helps limit deformation at the connecting sections with the bulkheads. That added rigidity supports smooth differential rotation and helps oil damper motion transfer properly into the chassis, so suspension input is carried more directly through the assembly. Laser engraving distinguishes this version clearly from Item 22079, which uses a 0.5 mm offset. Depending on surface conditions, that alternative offset can also be used as part of setup tuning. On high-grip surfaces, differential height becomes an important setup variable, and raising the differential can stabilize the car. That makes these holders a useful option when refining belt tension, comparing offset choices and preparing a TA08R or TRF420 platform for track-specific handling changes.
