This set includes a damper stay and front upper arm mount designed to convert the GRK5/GRK5-R to a cantilever upper arm setup.
The newly designed aluminum front upper arm mount accommodates the separately sold (R31S118) GRK RWD cantilever upper arm shaft.
The dedicated pure carbon front damper stay features multiple mounting holes at the nose cone attachment point. offering greater flexibility in damper height settings.
The simplified structure also contributes to reducing weight in the front end.
Combining this set with the simultaneously released (R31S136) 0.5mm aluminum upper arm spacers allows for even finer caster angle adjustments.
*Note: The (R31S118) cantilever upper arm shaft is required separately to perform this conversion.
