R31 HOUSE GRK5 ALUMINUM GEARBOX (BLACK)(R31S328BK)

The aluminum gearbox used in the GRK5 is now available as an optional part for the GRK!

The new gearbox, which adopts a heavy design like the differential case of a real car, is about 8g heavier than the conventional aluminum gearbox (R31W279/R31S310) in order to optimize the
axle load balance as a RWD drift machine . Of course, it can be used to change from the plastic gearbox of the GRK Global Series. Even cars equipped with conventional aluminum gearboxes such as the GRK4 can expect an increased traction effect. 〇Applicable car models GRK5 standard parts GRK4 GRK3 GRK Global Series (R31S328) GRK5 aluminum gearbox (various colors)
