GPM Racing 7075-T6 Alloy Rear Sway Bar Set for Vanquish 1/10 H10 Optic Kit (H10312)

Technical overview H10312 rear sway bar for H10 Optic platforms

The H10312 rear sway bar set delivers a precision-engineered aluminium upgrade for H10 Optic rear mounts, concentrating on increased torsional stiffness and long-term fatigue resistance. Components are CNC machined from 7075-T6 aluminium to retain dimensional accuracy and repeatable fitment across production runs.

Material specification and mechanical rationale

Using 7075-T6 alloy provides superior yield and tensile properties relative to common aluminium grades, reducing permanent deformation under lateral loads. The system employs a solid 2.5x128mm bar with matched arms and linkage rods to replicate conventional anti-roll behaviour once correctly torqued.

Fitment and assembly considerations

Fastener holes and geometry match VANQUISH H10 OPTIC rear mounting points for direct installation. The kit arrives pre-assembled where practical to ensure alignment; Grade 12.9 hardware is provided for critical joints and light thread locking is advised on main fasteners to preserve preload under vibration.

Pack contents and service notes

Contents include the rear sway bar, two arms, two linkage rods, and a set of black graded hardware including round head screws and set screws. Inspect hardware torque after initial runs and periodically thereafter to confirm retention and mitigate fatigue risk.

Use case and performance note

Designed for builders and competitive hobbyists who require a stiffer rear roll characteristic without altering suspension pick-up geometry, H10312 supports predictable chassis behaviour under cornering loads and repeated use.

H10312 is a precision, CNC-machined aluminium sway bar set intended to improve rear roll resistance while maintaining direct compatibility with H10 Optic rear mount geometry.

What inspection routine do you recommend after initial installation?

Verify fastener torque on Grade 12.9 screws after the first few runs, check linkage rod ends for play, and reapply thread locker to main screws if any loosening is observed.

How does 7075-T6 perform under repeated lateral fatigue?

7075-T6 offers higher static strength and improved fatigue characteristics compared with common aluminium alloys, making it suitable for components subject to frequent lateral loading, though visual inspection is recommended after heavy use.

Are replacement hardware packs available?

Replacement Grade 12.9 hardware should be sourced to match the supplied specifications; using lower grade fasteners in critical joints is not recommended. Write Product Review Please sign in your account before you can write any review. Sign In Close
