The Piston Rod Cylinder Shaft w/ Center Seal Gland & O-Ring Bushing Assembly from Buckshot Racing #77 is a high-performance replacement for SeaStar and Pro USA front-mounted hydraulic steering systems, designed to meet or exceed OEM specifications.
This 21.75 inch length and .75 inch diameter cylinder shaft is precision-engineered from marine-grade, chrome-plated cold-rolled steel, providing exceptional durability, corrosion resistance, and smooth operation in both saltwater and freshwater environments.
The center seal gland assembly consists of a high-precision polymer seal gland, a high-pressure marine-grade elastomer O-ring, and a self-lubricating composite bushing, all securely pressed onto the shaft for optimal hydraulic sealing.
The seal gland is engineered to precise tolerances, ensuring a side-to-side leak-proof interface within the hydraulic cylinder bore. The O-ring is designed to withstand extreme hydraulic pressures, resisting compression and deformation under prolonged use. The composite bushing offers superior low-friction performance, reducing wear on both the piston shaft and the cylinder bore while enhancing steering response.
This piston rod is a direct replacement for worn, bent, or pitted cylinder shafts in SeaStar HS5167 and Pro USA 350HP hydraulic steering systems, offering enhanced reliability, longevity, and smoother steering operation.
It is fully compatible with SeaStar part number HS5167 and replaces the piston rod in the following SeaStar cylinder models: HC5345, HC5347, HC5348, HC5358, HC5445, HC6345, HC6750, HC6751, HC6752, HC6753, HC6754, HC6755, and other brands with the same shaft sizes. Its OEM-compatible fit allows for seamless installation without modification.
Proper installation and maintenance include inspecting seals and O-rings for wear, ensuring adequate lubrication, and bleeding the hydraulic system after replacement to maintain optimal hydraulic performance.
Designed for marine professionals and high-performance boating applications, the Buckshot Racing #77 high-strength piston rod cylinder shaft meets or exceeds standard OEM durability and performance benchmarks, ensuring superior longevity, precision, and resistance to environmental wear.
By replacing to this high-quality component, high performance boat operators can restore their steering control, efficiency, and overall safety in demanding conditions.
