Improved Shock Seal

Gabriel Ride Control has developed an improved misting-reduction seal for its heavy-duty shock products, thereby extending service life and reducing overall downtime for maintenance. The enhanced seal is now available in the company’s FleetLine commercial truck, trailer, and bus shocks and GasSLX adjustable shocks.

The company’s goal was to solve one of the main problems that fleet operators see as an inevitable headache: oil escape from shock absorbers.

The demanding conditions present in heavy-duty vehicle applications cause misting in all shock absorbers over time. Misting occurs when the oil within the shock absorber, critical to ride control performance, slowly leaks out of a seal, coats the outside of the shock absorber, and accumulates dust and debris. This oil escape causes diminished shock-absorbing capabilities and eventual product failure.

With Gabriel’s improved misting-reduction seal technology, oil escape is said to be reduced by up to 70% over time. This leads to extended service life as well as improved performance over time.
