Tailgate Ramp Spring | Loader Spring for Horse Floats & Ramps
Heavy-duty steel torsion springs designed to assist in safely lifting and lowering heavy tailgates, horse floats, and ramp loaders.
Available in 40kg to 100kg+ capacities to ensure smooth, controlled, and injury-free operation.
Product Description
Operating heavy ramps and tailgates shouldn’t be a safety hazard. This premium Tailgate Ramp Loader Spring is engineered to take the strain out of loading and unloading. Manufactured from high-quality steel, these torsion springs store and release rotational energy, making heavy lifting effortless. Whether you are building a new car trailer, upgrading a low loader with drop axles, or replacing an old horse float spring, these components provide crucial mechanical assistance to prevent back injuries and accidental drops.
Because every trailer layout is unique, these springs come in specific Left-Hand and Right-Hand configurations. Additionally, the spring holders are proudly laser-cut and machined locally right here in Brisbane, helping you support high-quality Australian manufacturing and Aussie families.
Please note: We do not provide installation advice because spring holders can be welded to the chassis in various ways. For your safety, we strongly recommend installation by an experienced professional.

Frequently Asked Questions
How do I choose the correct spring size?
Do not guess the weight of your tailgate. Buying the correct size requires a simple measurement:
- Place a weighing scale on the ground where the ramp lowers.
- Lower the ramp directly onto the scale. Use a small piece of wood between the ramp and the scale to prevent scratching or damage.
- Note down the weight reading.
- Select a spring size that is 10kg less than the scale weight.
What happens if I buy a spring that is too heavy?
Many buyers mistakenly buy the largest spring to ensure maximum lift. If the spring is too heavy, the tailgate will only lower halfway because the spring’s tension resists the ramp’s weight. Over-specifying your spring can also cause the tailgate to swing up violently and slam into the trailer, causing severe structural damage.
How do I tell a Left-Hand spring from a Right-Hand spring?
To determine the orientation you need, stand with the spring’s smaller tail end pointing away from your body. Look at which side the longer tail sits on. If the long tail sits on your right side, you require a right-hand tailgate ramp loader spring. If it sits on the left, you need a left-hand spring.

Can you help me install my spring?
We do not provide installation instructions or advice. Spring holders can be welded to the trailer chassis in several different configurations, depending on your layout. Because torsion springs store extreme mechanical energy, we strongly advise having them installed by an experienced professional installer.
