Fitment Notes

• Fits the Holden VF Gen F and equivalent Zeta-platform vehicles only. Does not fit the Holden VE Commodore (2006-2013), which uses a different caster arm design and a separate SuperPro part number.
• Fixed geometry - stock-length, non-adjustable replacement arms. Does not alter caster angle from OEM specification.
• Sold as a pair (left and right). SuperPro strongly advises replacing both arms at the same time to maintain correct geometry and consistent handling response across the front axle.
• Front wheel alignment is required after installation.
• Compatible with all engine and trim variants across listed platforms where the front suspension architecture is shared.

Features

• OEM-quality alloy arm construction delivers greater rigidity and resistance to deformation than the original arms under high-stress braking, cornering, and acceleration loads.
• Pre-installed SuperPro hybrid polyurethane bushings at the chassis mount eliminate the flex and compliance of the OEM rubber bushing, maintaining consistent front caster and wheel alignment geometry under dynamic loads.
• Uprated heavy-duty ball joint replaces the fast-wearing OEM version, providing a more durable and precise connection at the knuckle end with reduced play over the service life of the arm.
• Eliminating OEM rubber bushing compliance reduces the dynamic variation in front caster angle under braking - a primary cause of front-end vagueness and reduced steering confidence during hard deceleration on the VF/Zeta platform.
• Improved steering response and straight-line tracking stability are achieved by preventing the front wheel from moving rearward under longitudinal braking force, which is the core function of the caster/radius arm on this suspension architecture.
• Optimised for longevity, durability, and performance without any unwanted increase in NVH compared to OEM rubber bushings, thanks to SuperPro's proprietary hybrid polyurethane formulation.
• Direct bolt-in replacement - no modification to the chassis, subframe, or any other suspension components required.
• Designed, tested, and engineered in Australia by SuperPro for both street and performance driving applications.
• Covered by SuperPro's 3-year warranty on all TRC Roll Control metal components.

Product Description

The SuperPro TRC1011 is a front caster arm (radius rod) replacement kit engineered for the Holden VF Commodore platform and its US-market equivalent, the 2014-2017 Chevrolet SS. These rear-wheel-drive Zeta-platform vehicles use a front suspension design in which the caster arm - a longitudinal link running fore and aft - is responsible for maintaining the front wheel's position under braking and acceleration forces, and for preserving consistent front caster angle. The OEM rubber bushing in the chassis mount of this arm is one of the first components to deteriorate, and as it softens and deflects under load, it allows the wheel to move rearward during braking. This manifests as front-end vagueness, reduced steering confidence at the limit, and inconsistent alignment geometry between static and dynamic conditions - a well-documented characteristic of these vehicles once the OEM rubber begins to age.

The TRC1011 addresses this directly by replacing both caster arms with units built from OEM-quality alloy and fitted with SuperPro's pre-installed hybrid polyurethane bushings at the chassis mount position. These bushings eliminate the compliance of the OEM rubber while retaining acceptable NVH through SuperPro's carefully tuned hybrid polyurethane formulation - stiffer and more dimensionally stable than rubber without the harshness of a solid or purely rigid replacement. Each arm also includes an uprated heavy-duty ball joint that replaces the fast-wearing OEM unit, providing a longer-lasting, more precise connection at the knuckle end. The result is a front suspension that tracks accurately under hard braking, provides crisper steering response, and maintains consistent wheel alignment geometry throughout the suspension travel range.

These are fixed-geometry, stock-length replacement arms - they restore the OEM caster angle with superior bushing durability and arm rigidity, without altering wheel alignment specifications. SuperPro strongly recommends replacing both arms at the same time to ensure a matched front suspension response across the axle. Installation is a direct bolt-in procedure with no chassis modification required, and a front wheel alignment must be performed after fitting. Note that this kit is specific to the VF Commodore / Chevrolet SS platform - owners of the earlier Holden VE Commodore (2006-2013) should confirm their model year before ordering, as that platform uses a different caster arm part. All TRC Roll Control metal components are covered by SuperPro's 3-year warranty, with no exclusions for performance or track use.
