This started in another thread about rear spring alternatives, but I thought it may help others find it if I moved it to its own thread. Another member, Neilca, found out that Land Rover uses coil springs with the same inner diameter (5”) as the R50. This is a great find, because LR offers many spring options with much higher spring rate than what is typically available for the R50, and in many different heights as well. A chart of spring specs can be found here:
