GPM Racing Stainless Steel Front Sway Bar & Aluminium Sway Bar Arm & Stainless Steel Linkage-12pcs Set for Traxxas 1/7 Unlimited Desert Racer-85076-4 (SUDR312FS)

Front sway bar technical overview

The 12-piece front sway bar kit is engineered for the TRAXXAS UNLIMITED DESERT RACER platform and replaces OEM components with stainless steel and aluminium pieces to modify front roll stiffness and tie-rod geometry. The assembly upgrades the stock front sway bar and arms to a thicker stainless steel section paired with aluminium sway bar arms that present two tie-rod mounting positions for precise leverage adjustment.

Installation requires removal of the factory front sway bar items, correct seating of the stainless steel sway bar into the original mounts, and the use of the supplied 3.5mm reamer where factory holes are undersize. All securing hardware is supplied to retain the arms and linkages; selecting inner or outer tie-rod holes changes the arm angle and effective roll lever arm.

From an engineering perspective, the kit increases the torsional stiffness of the sway assembly and provides two discrete leverage ratios through dual arm positions, enabling measurable changes in roll gradient and transient response for track tuning.

Use the dual-arm positions to quantify changes in roll stiffness during test sessions and document which hole correlates with preferred handling; always verify hole alignment and fastener torque after the initial runs.

What measurable effect does the thicker bar have?

The increased section stiffness raises roll resistance and reduces lateral body roll, which can be observed as a quicker transition into cornering and less chassis lean at steady corner speeds.

How should I set up for testing changes?

Record baseline handling, then change only the tie-rod hole and run identical laps to evaluate differences; log lap times and subjective feedback to determine optimal leverage settings.

Are there torque recommendations for the fasteners?

Use medium torque appropriate for small stainless fasteners and re-check after initial runs; avoid over-torquing aluminium arms to prevent deformation of mounting features. Write Product Review Please sign in your account before you can write any review. Sign In Close
