Grayston Coil Spring Assistors and Raisers are an easy to fit solution to give an uprated spring rate and help prevent the vehicle from bottoming out whilst towing or carrying heavy weights where the springs can't cope with the load.

They are designed to be used as a temporary measure and are quick and easy to fit and take out, making them ideal for the once a year family holiday or trip to the tip with a heavy load. Grayston coil spring assisters are manufactured in a hard rubber compound and can be fitted by the average motorist without special tools. They are progressive in operation and are available in a range of sizes that allows them to be fitted to most vehicles. They are ideal for use when towing a caravan, trailer, trailer tent, carrying bikes on a tow-bar mounted rack or whenever the vehicle is carrying a heavier load than normal. Coil spring assisters can prevent the vehicle from bottoming out, help reduce light steering, stop suspension sag and help prevent the headlight beam aiming too high.

This listing is for one (1) spring assister in the chosen size from the drop down box. The spring gap shown in the drop down box should be measured when the car is jacked up and is the distance between the coils where the spring assisters will be fitted (ideally in the middle of the coil spring).

Sizes available:

Small - suit 18-25mm spring gap Medium - suit 26-38mm spring gap  Large - suit 39-51mm spring gap XLarge - suit 51-65mm spring gap

Choose the correct size to suit your vehicles spring gap, measured when one wheel has been jacked up off the ground.

Important: Spring assisters should only be fitted to the rear of a vehicle and fitted in pairs.
