Hot Racing High Lift Springs are an extra-lift cold-coiled shock spring option for the Traxxas E-Revo, Revo 3.3, Slayer Pro 4X4, and Summit. These springs are approximately 5mm longer than the stock springs to help compensate and raise the vehicle after adding heavy duty upgrades or high capacity batteries. Adding these springs will add 5 to 10 percent more ground clearance to the vehicle, depending on the vehicle components installed.

Coil springs can be either "hot-coiled" or "cold-coiled". Hot Racing springs are cold-coiled and are wound from pre-heat treated spring wire stock. This produces a superior spring versus many other so-called performance springs that are "cold-coiled" from annealed "bundle stock," then quenched and tempered after coiling. This inferior method produces a less accurate spring and can result in surface imperfections.

• Cold-coiled spring steel construction
• Plated with a distinctive chip-resistant gold finish
• 5mm longer than stock springs to raise ride height or compensate for heavy components
