Shock Adjuster Caps
Shock Caps replace the plastic OEM shock cap. The internal cylindrical cavity has four grooves for adjustability in 1/4-turns. When you remove the OEM cap, be careful not to lose the ball and spring. The top of the adjustment valve has a hexagonal shaft. The inside of the RCU Cap has a 13mm machined hexagonal recess. If this is too large for your OEM valve shaft, an adapter(s) is included in the kit. The Cap is machined from billet 6061 aircraft quality aluminum alloy and natural-color anodized. The retention screw is included with installation directions.
The BMW roundel is included with each Adjuster Cap.
Should you happen to lose the ball and/or spring, we have replacements available. RCU 99000 $6.00/set
