Steel Double Adjuster 3/4in

The ALLSTAR PERFORMANCE Steel Double Adjuster 3/4in (ALL 56197) is a precision linkage adjuster designed for fine-tuning mechanical connections in high-performance applications. Built from steel with a black oxide finish, this double-ended adjuster features 3/4-16 right-hand male thread on one end and 3/4-16 left-hand male thread on the opposite end, allowing for dual-directional adjustment and precise length control without removal from the assembly.

The dual-threaded design accommodates opposite-hand connections simultaneously, making this adjuster ideal for situations where a single component must interface with threads running in opposite directions. The 3/4-16 specification indicates a 0.75-inch diameter with 16 threads per inch—a common size in automotive linkage systems where mechanical precision directly impacts throttle response, shift quality, and clutch engagement. Black oxide coating provides corrosion resistance and a finished appearance suitable for engine bay installation.

Technicians and builders working on custom engines, transmission conversions, and performance fuel or ignition systems use linkage adjusters like this to establish correct geometry and travel in mechanical control systems. The steel construction and threaded design allow infinite micro-adjustments without special tools, and the compact 4.05 x 1.12 x 7 inch profile fits tight engine compartments where space is limited.

ALLSTAR Performance is recognized for manufacturing linkage and mechanical components to OEM and racing standards, and this adjuster reflects that focus on precision and reliability. At 0.8 lbs, it integrates easily into existing assemblies, and the dual-thread configuration eliminates the need for multiple single-ended adjusters in applications requiring bidirectional control.
