Sway Bar Adjuster Bolt Detented

The ALLSTAR PERFORMANCE Sway Bar Adjuster Bolt Detented (ALL 99189) is a precision fastener engineered for adjustable sway bar arm systems in high-performance suspension tuning. This 1/2-20 thread, 2.5-inch long bolt features a 12-point head design and black oxide finish, making it the critical hardware component for fine-tuning anti-roll bar geometry on road course and drag racing applications. The detented feature provides positive click-stops at pre-set adjustment positions, eliminating drift and ensuring repeatable suspension setup between runs.

Manufactured from steel with black oxide coating, this sway bar bolt resists corrosion and wear under the constant micro-motion and vibration cycles inherent to adjustable suspension systems. The 12-point head accommodates precision socket engagement without rounding, critical when tightening to spec torque values on a loaded suspension. At 0.17 lbs per unit, weight is negligible, but the engineering is not—every detent increment changes roll stiffness in measurable fractions, making hardware precision foundational to consistent lap times and handling feel.

This fastener is essential for racers and suspension tuners who demand locked, verified adjustment positions. Road course competitors rely on repeatable sway bar settings across weekend sessions; drag racers require stable geometry under launch loads. The detented design prevents accidental shift during transport or on-track vibration, eliminating variables that compromise setup repeatability.

ALLSTAR PERFORMANCE is recognized in motorsports circles for manufacturing suspension hardware that meets OEM tolerances and race-proven durability standards. This bolt is a foundational component in adjustable sway bar systems found across street-strip cars, road race platforms, and dedicated drag racing vehicles where suspension tuning is non-negotiable.
