Steering parts are the critical components that connect your steering wheel to the road, translating driver inputs into precise, controlled wheel movement. Over time, worn steering components lead to vague, loose steering, uneven tyre wear and reduced driving confidence. Our range of steering parts includes tie rods, steering knuckles and idler arms, offering durable, high-quality replacements designed to restore tight, accurate steering response and keep your vehicle tracking true.
Worn steering components allow excess play throughout the steering system, which results in vague response, wandering under load, clunking noises and uneven tyre wear. As wear progresses, steering geometry shifts, making alignment harder to maintain and accelerating wear on surrounding components such as tyres, bushes and hubs. Replacing worn steering parts restores proper geometry, tightens response and brings back the direct, confident feel your steering was designed to deliver. It's one of the most important maintenance steps for safety, tyre life and overall driving confidence.
Our steering parts are built using high-quality materials and precision manufacturing to deliver reliable performance, long service life and accurate fitment. Each component is engineered to meet or exceed factory specifications, with durable construction that resists wear, corrosion and load stress. From direct-fit replacements to performance-grade options, our range offers solutions for everyday driving, 4WD use and performance applications. Whether you're maintaining a daily driver, restoring an older vehicle or upgrading a modified build, our steering parts deliver the quality and consistency you can rely on.
Our steering parts range covers the key components needed to maintain accurate, responsive steering:
Steering parts work together to translate driver inputs into accurate wheel movement, and every component plays a role in how direct, responsive and predictable the steering feels. Fresh, high-quality parts reduce unwanted play and deflection, keeping steering geometry consistent and ensuring inputs at the wheel translate straight to the tyres. This delivers sharper turn-in, improved straight-line stability and more predictable handling through corners. Quality steering parts also protect surrounding components from accelerated wear, extending the life of your tyres, bushes and alignment.
Our steering parts are available for a wide range of vehicles, including:
If you're unsure which steering parts suit your specific vehicle, get in touch and we'll help you find the right fit.
Steering part replacement is best suited to experienced DIY installers or professional workshops, as correct torque, alignment and fitment are critical to safe steering performance. Each component is engineered for direct fitment to make installation as straightforward as possible, and a wheel alignment is strongly recommended after fitting. If you have any questions about fitment, specifications or selecting the right steering parts for your vehicle, our team is here to help.
Browse our full range of tie rods, steering knuckles and idler arms to find the right solution for your vehicle. Order today and restore the precision, stability and control your steering was designed to deliver.

KCA514 Steering Knuckle Kit - Bump Steer Correction
Optimizing Steering Geometry for Better Handling and Safety
The KCA514 Steering Knuckle Kit is designed to improve steering geometry and reduce bump steer. It is completely legal and doesn’t require engineering certification or modification plates. This product is VSB 14 approved and ADR compliant. It functions similarly to installing an upper control arm in your vehicle.
Our engineering team has rigorously tested the aftermarket front knuckle (KCA514) to VSB 14 load standards using FEA analysis, assessing it for a front axle rating of 1650kg. The tests confirm that the product exceeds strength requirements. It is compatible with any GVM upgrade.
VSB 14 outlines legal requirements for aftermarket modifications. The KCA514 knuckle is classified as owner-certified, meaning no engineer or certification is needed once installed. This is similar to installing legal modifications such as upper control arms, shocks, or lift kits.
The Australian Design Rules (ADRs) set national safety, anti-theft, and emissions standards for vehicles. While there are no specific ADRs for steering knuckles (similar to control arms or shocks), the KCA514 steering knuckle meets OE (Original Equipment) design standards. As there are no ADRs governing the "robustness of a vehicle," VSB 14 is the primary standard for in-service modifications.
Other similar in-service bolt-on modifications that don’t require engineering or mod plates include:
Whiteline products undergo extensive testing to ensure compliance with relevant engineering standards, offering peace of mind regarding quality.
These vehicles experience chronic bump steer, which leads to significant tire wear. This issue is apparent in both standard-height and lifted versions, but becomes more severe with lift modifications.
The KCA514 steering knuckle provides a direct replacement, replicating all original features and mounting provisions. Made from hot-forged 4140 AISI steel, it’s heat-treated and finished with black e-coat for optimal corrosion resistance.
Pairing KCA514 steering knuckles with upper control arms resolves premature tire wear, improves alignment, and restores proper handling.
No. While wheel alignments may temporarily reduce tire wear, they don’t fix the underlying problem. Alignments are a band-aid solution, not a permanent fix.
After extensive testing, we’ve learned that while an upper control arm may slightly improve bump steer, it doesn’t provide a full solution. Adjusting the steering rack pickup point is necessary to properly address bump steer. Using an upper control arm to fix bump steer would cause other issues, such as tire clearance problems.
The Whiteline steering knuckle is engineered to correct bump steer without introducing new complications.
Bump steer refers to changes in the vehicle’s toe as its ride height changes, especially when driving over bumps. This is particularly problematic when towing, carrying heavy loads, or using a suspension lift. Excessive bump steer causes premature tire wear, as demonstrated in real-world field tests and R&D.
The Whiteline steering knuckle relocates the tie-rod pickup point to optimize the steering geometry and reduce bump steer across different ride heights. Testing shows a 75% reduction in bump steer when these knuckles are installed in lifted vehicles. When installed in standard-height vehicles, bump steer is reduced to nearly zero.
Combining the KCA514 knuckles with offset upper control arms can reduce bump steer by an additional 10-15%.
