Double Adjuster - 3/4in x 3/4in

The QA1 Double Adjuster – 3/4in x 3/4in (part number ADJ12-12) is a precision linkage adjuster engineered for suspension and steering geometry fine-tuning in performance and competition vehicles. This steel adjuster features a 3/4-16 left-hand male thread on one end and a 3/4-16 right-hand female thread on the other, allowing dual directional adjustment without requiring separate removal. The double-ended design makes it essential for maintaining proper suspension alignment when adjusting track bars, control arms, and drag link components.

The dual-thread configuration delivers independent left-hand and right-hand adjustment capability, which is critical when camber, caster, or toe-in corrections are required simultaneously on opposing suspension points. Steel construction provides the rigidity and corrosion resistance needed for long-term fastening reliability. The 3/4-inch size accommodates standard suspension components commonly found in street rods, classic restorations, and modern performance platforms where adjustability is prioritized over fixed geometry.

This adjuster is designed for technicians and fabricators who require precise steering and suspension tuning without full component replacement. Whether adjusting a hot rod's steering geometry, modifying a race car's suspension alignment, or custom-building a performance suspension system, the dual-adjuster approach eliminates the need to swap components. Each unit is sold individually, allowing buyers to purchase exactly the quantity required for their project. The compact dimensions (2.8 x 1.2 x 4.95 inches) fit within restricted suspension spaces typical of street rod and custom chassis applications.
