Product Description
The long-awaited optional Carbon Upper Arm Plate for GRK4 users is finally here!
This lightweight carbon plate is approximately 2.3g lighter than the standard aluminum upper arm plate included with the GRK4 kit.
When combined with the simultaneously released [R31S319] W-Position Front Damper Stay, it further contributes to reducing the overall front-end weight of your chassis for improved balance and performance.
