Extension Springs

Springmakers manufacture a wide a variety of extension springs to our customers' exact specific requirements. Our full design and prototyping service allows the time between initial conception to working product to take only a matter of hours. Effective spring design is critical to ensure longevity as most breakages/failure occur, we specialize in solving these problems and provide workable solutions.

Available in many different end-type configurations, such as: threaded inserts, swivel eyes, crossover center loops, hooks, expanded eyes, reduced eyes, rectangular ends and teardrop-shaped ends, which can all be produced to vary the distance from the spring body. At the design stage, the length of the hooks at each end of the spring can be adjusted in order to precisely obtain the required spring load at any extended position.
