GRK5-R GRK5 18T Aluminum Bevel Gear [Shibata] R31S138

(GRK5RYH) This is an 18T aluminum bevel gear compatible with the GRK5, which

was first adopted in the GRK5-R HRP full kit. Developed to meet the gear ratios required for ultra-high RPMs in drift competitions, this is an advanced model. Secondary reduction ratio 2.166

○ Applicable models : GRK5 , GRK4 (*) , EVO-R (*) , GS2NOB *(R31S067) Compatible when combined with the GRK5 gear adapter. Cannot be installed with the standard GRK4 gear adapter (R31S302).

○ Compatibility with various differential specifications 1…(R31G001) In the case of a ball differential specification This can be achieved by changing the ring gear to the (R31W211) ball differential offset ring gear. Final backlash adjustment should be done with shims on both sides. 2…(R31W271) For gear differential specifications The ring gear should be configured in a 16T to 18T configuration. Final backlash adjustment should be done using shims on both sides.

〇Other points to note: If the mounting position of the universal shaft and joint cup is misaligned, the universal shaft may not engage properly, or it may interfere with the bottom of the joint cup, potentially hindering the movement of the suspension. In that case, the universal shaft must be changed to one of appropriate length.
