Super Tramp uses their patented zinc-plated tapered springs which react to the weight of each individual user giving optimum performance. This means that different parts of the spring are put under pressure by different users, depending on their weight and ability. This improves the performance and life of the spring, whilst the elongated hook makes it much easier for you to fit them into the frame.

These 8.5" springs with elongated hook are designed to fit the following Super Tramp models:

King 110
Fun Bouncer 12ft
Super Bouncer 14ft
XR360 Rectangular
Evo 12 & 14
TrailaTramp 6 trailer-mounted multibed system
These springs are also suitable for use on other brands of trampoline that use 8.5" springs.

Frequently Asked Questions

Will new trampoline springs improve bounce height and performance?

Yes. New springs restore proper elasticity and tension, resulting in stronger bounce height, smoother rebound, and improved jumping control.

Can old springs affect trampoline safety?

Worn springs reduce tension balance and bounce control, increasing strain on the trampoline structure. Replacing them improves stability and overall safety.

How many trampoline springs should be replaced at once?

Replacing multiple worn springs ensures balanced tension and optimal performance. Many trampoline owners replace springs in sets to restore consistent bounce.

Are these springs suitable for home garden trampolines?

Yes. These replacement springs are designed for domestic trampolines used in home gardens across the UK.

Do replacement springs help extend trampoline lifespan?

Yes. Proper spring tension reduces strain on the mat and frame, helping extend the overall life of your trampoline.

Which spring do I need?

Remove one spring and measure it from hook to hook. It will have stretched slightly with use, so round down to the nearest standard size (5.5, 7, 8.35, 8.5, 8.57 and 9.25 inch). This page is for the 8.5 inch (216mm) spring. If you are unsure, our team can confirm the size from your trampoline model or your measurements.

How do I fit replacement springs?

Adult installation is required. Wear protective gloves, as the hooks are sharp. Hook the spring tool onto the spring hook in the frame, then pull up and towards you to release the old spring. Each new spring has a standard hook, which goes onto the steel bed triangle, and an elongated hook, which goes into the frame. Pull the spring to the frame with the tool, push down on the spring body until it slots in, then release the tool. If you are fitting a full set, work in opposite pairs, like the points of a compass, so the tension stays even. See our installation guides.
