Shaft Wiper - .625 Poly Blue

The Penske Racing Shocks Shaft Wiper in .625 poly blue is a precision seal component engineered to protect shock absorber rod surfaces from contamination and wear during high-performance racing applications. This polyurethane wiper fits 5/8-inch shock shafts and serves as a critical barrier between the rod and external debris, extending seal life and maintaining consistent damping characteristics throughout an event or season.

Measuring 1.9 x 0.3 x 2.85 inches and weighing just 0.03 lbs, this wiper is lightweight and compact—essential attributes for racing platforms where every component contributes to overall system efficiency. The polyurethane construction provides reliable scraping action to remove moisture, dust, and particulates that accumulate during track use, protecting the internal piston rod geometry and O-ring seals from micro-abrasion and corrosion. Penske Racing Shocks, a recognized leader in OEM and aftermarket shock technology, engineers these wipers to withstand the rapid compression and extension cycles characteristic of motorsports suspension systems.

This wiper is essential for drivers running open-wheel racing, road course competition, off-road circuit racing, or any high-intensity application where shock durability directly impacts handling consistency and lap times. Track teams use shaft wipers as preventive maintenance components—replacing them at regular intervals ensures that suspension performance remains predictable and that seal assemblies do not fail prematurely due to rod contamination. Sold individually, this part (SL-09) integrates seamlessly into Penske Racing Shocks assemblies where 5/8-inch shaft diameter is specified.
