TRC6590 Fixed Offset Control Arm Kit & TRC6680 Steering Knuckle Kit - Bump Steer Correction - designed to optimise the steering geometry
This product does not require engineering or mod plating and is completely legal.
Our engineering team have both assessed and conducted 3rd party testing on the aftermarket front knuckle (TRC6680) to VSB14 loads, for a front axle rating of 1650kg using FEA analysis. It has been found to comply and exceed the strength requirements. This product can be fitted with any GVM upgrade.
VSB 14 & How this product is compliant & legal
VSB 14 is the legal underwriting that affects aftermarket modification, where TRC6680 is classified as owner certified. Meaning that no engineer or certification is required after the product has been installed. This works the exact same as installing an upper control arm, shock, legal lift kit, spring or airbag kit.
ADR & How this product is compliant & legal
The Australian Design Rules (ADRs) are our national standards for road vehicle safety, anti-theft and emissions. All new road vehicles manufactured in Australia and imported new or second-hand vehicles, must comply with the relevant ADRs when they are first supplied to the Australian market. There is no specific underwriting related to steering knuckles, the same as there isnt for control arms, shocks, etc. As such there is no ADR compliance to be followed. However, when testing this product it met OE design standards.
It is essential to highlight that there are no Australian Design Rules (ADRs) specifically addressing the 'robustness of a vehicle.' Consequently, VSB14 serves as an excellent guide and, in practice, is the primary standard to reference when considering 'in-service modifications.'
Comparison examples of other in-service bolt in modifications that also do not require engineering / mod plate certification but are a similar replacement part / upgrade to the superpro steering knuckle, include:
1. Leaf spring - Parabolic vs. original: Despite notable differences in shape and design, both comply with Original Equipment (OE) standards.
2. Front Strut - OE to Formula 4x4 or equivalent: Transitioning from the OE to Formula 4x4 or an equivalent strut demonstrates conformity.
3. Bull Bar - Before and after fitment: The installation of a bull bar poses no issues.
4. Control Arm - Replacing a steel control arm with an Alloy Control Arm: This substitution maintains compliance with standards.
SuperPro components, implemented as 'in-service modifications,' have undergone rigorous testing in accordance with appropriate engineering standards, instilling unwavering confidence in the quality of our products.
Benefits
This is a combined kit, that includes a SuperPro fixed upper control arm that gives you additional CAMBER and CASTER, alllowing you to get a correct alignment once your 4WD is lifted. The kit also includes the SuperPro steering knuckle upgrade to fix TOE, which is a issue on both factory (standard height) and lifted D-MAX's, BT-50's and MU-X's. This combined package will fix all tyre wear, alignment problems and improve your handling.
- Vastly improved handling and overall vehicle dynamics (building driver confidence and supporting the fact that the car “just feels a whole lot better”)
- Improved stability (day-to-day driving as well as touring/off-roading)
- The driver will not have to constantly correct the steering (or fight lane change assist)
- Less driver fatigue meaning higher levels of concentration and reduced chance of being involved in an
