Ultra Racing proudly announces the launch of its latest suspension enhancement solution — the Ultra Racing Spring Buffer, a product developed through patented design and industry-level engineering standards. The launch has also been featured in Sin Chew Daily, highlighting the market’s growing recognition of Ultra Racing’s commitment to innovation, performance, and driving comfort.
With years of experience in chassis and suspension reinforcement, Ultra Racing continues to expand its product portfolio by delivering solutions that are not only performance-driven but also engineered to work in harmony with the vehicle’s original suspension system.
The Ultra Racing Spring Buffer is currently PATENT PENDING, with the application submitted on 31st October 2025. While patent approval may take several years, this product already represents a world-first innovation in spring buffer design.
It is the only dual-layer spring buffer in the world engineered to combine a soft outer layer for comfort with a reinforced inner core for controlled suspension support. Ultra Racing’s patent-pending Spring Buffer showcases a truly original engineering approach, setting a new benchmark in suspension enhancement worldwide. It demonstrates Ultra Racing’s commitment to pushing boundaries and delivering unique, performance-driven solutions that cannot be found anywhere else in the market.
The Ultra Racing Spring Buffer is engineered with a precision-formed, dual-layer structure that fits seamlessly between the coil spring gaps, designed to deliver enhanced suspension support only when required, without affecting comfort during normal driving conditions.
It was features a precision-engineered dual-layer design, with a soft outer layer that absorbs road impact and vibration, and a reinforced inner core that delivers controlled support under load. Its intelligent on-demand operation allows the buffer to remain inactive during normal driving and activate only when encountering speed bumps, cornering, uneven road surfaces, or braking. This design helps optimize load distribution, reducing uneven stress on coil springs while preserving natural suspension movement. Manufactured from high-durability TPU (thermoplastic polyurethane), the Spring Buffer offers excellent elasticity, wear resistance, and long-term shape retention. It is also widely compatible, fitting aftermarket and height-adjustable coil springs, and covering approximately 90% of coil spring models on the market.
Traditional spring buffers are typically made from generic rubber or basic polyurethane materials and are installed at a fixed position within the coil spring, often secured with cable ties only. While this may provide basic cushioning, constant engagement and the risk of loosening or cracking on the road can compromise suspension performance and potentially place the driver in danger. These buffers can also restrict natural suspension movement, create uneven stress on the springs, and lead to premature wear, resulting in a stiffer, less comfortable ride.
In contrast, the Ultra Racing Spring Buffer is securely installed with bolts and nuts, along with a specially designated Z-clip, eliminating risks associated with loose or damaged components. On-demand design not only improves suspension performance and stability but also preserves comfort and maximizes safety, making it a superior solution compared to traditional buffers.
The launch of the Ultra Racing Spring Buffer marks another step forward in Ultra Racing’s mission to deliver engineering-driven performance solutions. Backed by patented design, durable materials and wide coil spring compatibility, this product sets a new benchmark in spring buffer technology.
Ultra Racing remains committed to innovation, quality, and performance. To develop products continuously that meet the evolving demands of drivers worldwide.
