Kyosho BB 1.6mm 2-Hole RC Shock Piston - W5303-09

The Kyosho W5303-09 BB Shock Piston is a replacement shock absorber component designed for use with Kyosho RC cars that use ball-bearing (BB) type shock units. Part number KYOW5303-09, this piston features a 1.6mm orifice diameter with a two-hole configuration, which controls the flow of shock oil and directly affects how the suspension responds over different surfaces. Having the correct piston specification on hand is essential when servicing or rebuilding Kyosho shocks to maintain consistent suspension performance.

Key Features

• 1.6mm orifice diameter with a two-hole layout for controlled oil flow through the shock absorber
• Designed for Kyosho ball-bearing (BB) type shock units
• Pack contains two pistons, providing enough to service a pair of shocks in one go
• A direct OEM-spec replacement that keeps your suspension geometry and damping characteristics as intended
• Small, precise component — worth keeping in your spares kit if you regularly strip and rebuild your shocks

What's Included

• 2 x Kyosho BB Shock Pistons (1.6mm, 2-hole)

What You Need

• Compatible Kyosho RC vehicle with BB-type shock absorbers
