Trampoline Spring LEAN Sport 140 mm model 6811 for replacement and repair

LEAN Sport trampoline spring, 140 mm model 6811, is a replacement coil spring designed to restore proper bounce and tension to trampoline mats. Made to fit standard trampoline frames that accept 140 mm springs, this component is intended for maintenance and repair of recreational trampolines to ensure even rebound and consistent surface tension across the jumping area.

Advantages

This 140 mm replacement spring provides consistent elastic response and helps re-establish uniform tension around the trampoline perimeter. The coil construction offers predictable extension and recoil characteristics, making it easier to match the behavior of existing springs. Lightweight and straightforward to install, the spring is a practical option for repairing worn, stretched, or broken springs without replacing the entire trampoline suspension system.

Suitable for

• Repairing domestic or recreational trampolines that use 140 mm coil springs
• Replacing individual worn or broken springs to restore even tension
• Maintenance tasks that require matching spring length and elasticity with existing parts

When it may not be suitable

This spring is specifically 140 mm in length and intended for trampolines designed for that spring size; it may not fit frames or jumpers that require different spring lengths or connection types. It is not a complete suspension kit and does not include tools, connectors, or safety pads, so additional parts or adjustments may be necessary for a full repair.

Key specifications

• Spring type: coil replacement spring
• Nominal length: 140 mm
• Intended use: trampoline mat suspension / rebound component
• Material characteristics: steel coil with designed elasticity for trampoline rebound (surface finish and corrosion resistance depend on manufacturing batch)

How to use

Turn off access to the trampoline and ensure the jumping surface is unloaded before attempting replacement. Remove the damaged spring by detaching it from the frame and mat connection points, then install the replacement 140 mm spring by hooking one end to the frame ring and the other to the mat or connector. Work around the trampoline evenly, replacing springs in a balanced manner to maintain uniform tension. Use a spring pull tool if available to reduce strain and ensure secure attachment.

What to consider before purchase

• Confirm your trampoline requires 140 mm springs and that connection hooks match your frame and mat
• Check whether multiple springs should be replaced at once to maintain balanced tension
• Consider whether additional hardware, tools, or safety pads are needed for a complete repair

Usage recommendations

Inspect all springs periodically for corrosion, stretching, or damage and replace springs in matched groups when significant wear is observed to keep rebound even and reduce stress on the frame. When installing, use appropriate tools and follow manufacturer guidance for safe maintenance.
