Torsion Stop Bolt Steel With Nut Both 9/16 Heads

The Ti22 PERFORMANCE Torsion Stop Bolt Steel With Nut Both 9/16 Heads (SKU: TIP2388) is a precision fastening component engineered for high-performance suspension and chassis applications where torsion arm adjustment and secure locking are critical. This is a purpose-built assembly designed for users who demand exact, repeatable setup tuning and reliable holding power under dynamic load conditions.

The assembly features a steel bolt paired with a matching nut, both machined with 9/16-inch hex heads for standardized wrench fit and positive engagement. The specification ensures minimal slippage during installation and adjustment cycles—critical when fine-tuning suspension geometry on high-speed vehicles where even slight fastener movement compromises handling characteristics and consistency between setup iterations. The steel construction provides the strength necessary to secure components under compression and torsional stress without deformation, while the dual hex-head design allows simultaneous wrench engagement for secure tightening without bolt rotation or nut backup complications.

Users in sprint car racing, off-road suspension tuning, and chassis modification rely on components like this to maintain adjustment lock-in across multiple heat cycles and aggressive cornering loads. The simple, robust design eliminates dependency on locking compounds or secondary retention hardware, allowing mechanics and tuners to make rapid adjustments during pit stops or between sessions without waiting for chemical cure times. At 0.1 lbs, the assembly adds negligible unsprung weight while delivering the locking security required for repeatable performance data collection during testing and competition.
