Precision CNC machined 13mm 2mm thick piston, 1.6 and 1.7mm holes. The split valving had 1 hole drilled larger to 1.7mm so the piston has less low speed damping and won't pack up as quickly. Ideal for 2wd front when needing more low speed steering feel. Typically use 30wt to 32.5 wt oil when used in 2wd fron.
These pistons are sold 2 pcs per package and are hand marked "6 7" to denote the valving.
Fits B6.4 13mm shocks by Team Associated with "screw-on" piston.
