Stucki hydraulic stabilizers are the only hydraulic damping units guaranteed
to meet AAR Specification M-965, AAR Field Manual Rule 50 and Rule 88 to ensure safe operation of the freight car while controlling resonant rocking of high-center-of-gravity cars with D5 or D4 springs. The Stucki HydraShox™ products utilize a high pressure seal which provides superior performance and life while preserving oil reserve levels. This fluid loss is compensated for by the reserve oil. The Stucki HS-7 and HS-10 incorporate a low pressure seal on the piston rod, which may pass slight amounts of oil under normal operating conditions.

Our highest priority is to provide outstanding customer service and superior product quality. We strive to create long term successful relationships with all of our customers.
