My 2001 P38 Range Rover is sitting on its bumpstops, so I’m considering changing to coil springs. I understand that the regular coil-spring conversion rides at the standard height. Are there any suppliers of springs at different heights? David Ramage, Barcelona, Spain
My advice would be not to convert to coils. The choice of spring is limited – and replacements, should you need them, would need to be sourced from the manufacturer, which is often not easy a few years on.
Varied heights are generally only available if you have the correct spring rates and specifications, and order them from a dedicated spring manufacturer rather than a retailer of conversion kits.
For what a conversion would cost, you could overhaul the existing system. It’s quite easy to fit – it takes me longer to jack up, secure and lower the vehicle again than it does to change the air spring itself. The most common fault is the compressor seal failing. The system identifies a lack of air then shuts down. This is easily cured with a piston and liner kit for about £35.
Laptop-driven diagnostics are free to download from rswsolutions.com, where you can also buy the lead to connect to your P38. You can read the faults and even adjust the ride heights for each of the settings.
