Coil Conversion Kits

N70 Hilux Rear 05-14

A coil-converted Hilux offers a wide range of practical benefits for drivers, helping you to improve almost every aspect of your 4x4’s ride. Our Superior Engineering Hilux coil conversion kits are fully street legal and compliant, designed and built to the highest possible standards for everyday driving. These kits are supplied pre-fabricated for a quick and easy installation, meaning you can spend less time fitting parts and more time enjoying your high-quality 4x4 suspension.

You’ll also be provided with comprehensive instructions for your lift kit. Since we’ve covered all of the necessary testing, you’ll just need to find a qualified welder and suspension fitter to take care of the installation. Each Hilux coil conversion kit contains everything you’ll need for coil conversion, including all brackets, mounts, and control arms. The coils and shocks are not included by default, so that you can customise the ride, handling and lift height to suit your own specific needs.

All of these components together, equal more precise handling and a more comfortable ride for Hilux owners.
