UK vehicle applications and ride-height settings
All height figures below are changes relative to original equipment ride height. A negative figure means lowering; a positive figure means raising. TEIN distinguishes the maximum adjustable range from the recommended range established by testing. The maximum figure is not a recommended operating setting.
