Cross Shaft Alum. A-Arm for 5/8 Rod End

The Cross Shaft Alum. A-Arm for 5/8 Rod End is a precision control arm fixture engineered for marine hydraulic steering and trim systems on center console and offshore boats. Built by BSB Manufacturing, this aluminum A-arm connects your rod end clevis to the steering shaft, translating helm input into smooth, responsive rudder or trim tab movement. Anglers and boaters who demand reliable steering feel and positive feedback underway—especially in rough water or extended offshore runs—depend on quality linkage components like this to maintain confidence at the wheel.

Machined from aluminum and finished in natural bare metal, the cross shaft A-arm features a standard 6-inch center-to-center mounting span, designed to mate with a 5/8-inch rod end ball joint. The 13.45-inch length and compact 1.6-inch width allow this linkage to fit cleanly in tight engine compartments and transom assemblies without obstruction. Aluminum construction keeps weight minimal—just 1.16 pounds—reducing unsprung mass in your steering system while maintaining rigidity. This geometry ensures predictable input-to-output ratio, eliminating play and dead spots that degrade steering precision during critical maneuvering.

Retrofit and new-build installations alike benefit from this OEM-quality control arm, whether you're upgrading a mechanical or hydraulic steering setup on a 20-foot center console, a sportfish cruiser, or a tiller-steered skiff. The 5/8 rod end connection accepts standard SAE male ball joints, and the fixed-length design makes replacement straightforward—no adjustment needed once installed. Boaters upgrading aging steering systems, or those building custom control linkages for non-standard applications, will find this cross shaft a reliable foundation for responsive helm feel and years of corrosion-resistant service.
