Key Features of Spherical Bearings:

1. Suspension Adjustments: Jack screws are often used in adjustable suspension setups to fine-tune ride height, weight distribution, and corner balancing, optimizing a vehicle’s performance for the track.

2. Chassis Tuning: They can assist in tweaking chassis components like sway bars or anti-roll bars to improve stability during cornering.

3. Engine and Drivetrain Applications: Jack screws may be used for precise alignment or tensioning of drivetrain components like belts, pulleys, or linkages.

4. Body Panel Fitting: In racing, where aerodynamics are critical, jack screws can be employed to adjust body panels or splitters to ensure proper fitment and airflow.

5. Load Stabilization: Ideal for holding components in position during fabrication or assembly processes, especially in custom builds or race car construction.

6. Pit Adjustments: During races, jack screws allow quick and precise adjustments to critical components, saving valuable time.

Benefits in Automotive/Racing

• Precision: Their threaded mechanism enables highly accurate adjustments, crucial in racing, where even minor tweaks can make a significant difference in performance.

• Versatility: They can be applied across a range of systems, from suspension to drivetrain and bodywork, making them a multifunctional tool.

• Durability: Made from Steel, jack screws can withstand extreme loads and harsh conditions commonly encountered in racing environments.

• Ease of Use: Adjustments can often be made without fully disassembling parts, which is especially useful during quick pit stops or rapid tuning sessions.

• Cost-Effectiveness: They eliminate the need for custom-machined or one-off parts, reducing costs while maintaining precision and adaptability.

• Space Efficiency: Jack screws are compact and can be integrated into tight spaces, which is often necessary in race car builds.

Our Jack Screws are not only manufactured to the highest of quality control standards but are designed and engineered to an extreme duty construction, specific to the requirements of Australian Drag, Drift & Circuit Racers as well as Off-Road Race classes.
