The 8155 GTS Long Springs are high‑performance suspension springs designed to provide improved ride height and enhanced handling on vehicles requiring a longer spring length. Made from precision‑engineered materials, they deliver consistent spring rate and durable performance under varied driving conditions. These long springs fit compatible shock absorbers on select RC vehicles, helping to maintain proper suspension balance and traction. They are ideal for replacing worn springs or upgrading suspension performance on models that accept GTS long springs.
