Penske 8987 Series Shock

This damper provides a more extensive range of tuning and hardware options in order to fulfill each team’s specifications as well as the personal preferences of race engineers and riders. The 8987 is offered as a 3-way and 4-way adjustable damper and is designed to fine-tune both high and low speed shaft movements. The high-speed adjuster controls larger track inconsistencies that may disrupt the motorcycle, while the low-speed adjuster controls slow shaft movements that occur during corner entry and exit. When tuning the high-speed adjustment, the secondary valve shims are being preloaded, giving you different compression forces. The low speed adjustment meters the fluid and bypasses the piston in the adjuster, providing an adjustable combination of bleed and shim controlled damping. In effect, the combination of low speed and high speed adjustments will offer virtually unlimited tuning options. The 8987 Series damper is the ultimate tuning tool for the professional race team.
