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

The QA1 Double Adjuster – 3/4in x 3/4in (part number ADJ12-12) is a precision suspension adjustment component designed for builders and mechanics who demand fine-tuned control over vehicle geometry and ride characteristics. Whether you're setting up a custom street machine, performance street rod, or competition-level suspension platform, this double-ended adjuster allows you to dial in exact ride height and suspension angles without guesswork. QA1 has earned its reputation among serious automotive enthusiasts for producing quality adjusters that maintain repeatability and accuracy across thousands of adjustments.

This 3/4-inch by 3/4-inch adjuster features a dual-threaded design that lets you work from either end, giving you flexibility when space is tight or when you need to access the adjustment mechanism from a specific angle during installation or alignment work. The compact dimensions—2.8 x 1.2 x 4.95 inches—make it suitable for tight suspension bays where larger adjustment components won't fit. Machined from quality materials and engineered to QA1's exacting standards, this adjuster resists stripping and wear even under repeated adjustment cycles, ensuring your suspension settings remain locked in during hard driving or track use.

This double adjuster is ideal for builders working with QA1 coilover kits, adjustable control arm systems, or any suspension setup where fine geometry tuning is critical. Installation requires basic mechanical knowledge and hand tools; no special equipment needed. Verify your suspension component's threaded port size—the 3/4-inch measurement—matches this adjuster before purchase. Weighing just 0.63 pounds, it adds negligible unsprung weight while providing the precise adjustment capability that separates a well-dialed suspension from one that simply bolts together and hopes for the best.
