Heavy Duty Waist Drum Shape Design for Longer Service Life

Our springs are made of heat treated 60Si2Mn steel,compared with normal carbon steel springs of the same size, the force increased by 20% and the deformation risk is reduced by 40%.

Besides,these trampoline replacement springs adopt the best quality and tightest coil winding design, which has stronger elasticity and tensile capacity than straight sided springs, thus our trampoline springs are not easy to break and ensure safety.

Please Ensure that the Springs are Installed in the Correct Direction
