If you want better suspension at standard height, this is for you.
It's not uncommon to want a suspension kit that matches the standard height of your vehicle, simply because you want a better ride. And it's a simple thing to achieve at the front, as the ride height is governed by the coil spring being used - so it's simply a matter of applying an assembled strut that includes a lower coil spring, manufactured at factory ride height.
However this operation is a different kettle of fish on a ute that has leaf springs in the rear, because there is very limited demand for heavier rated leaf springs at standard height - so the after market manufacturers do not make leaf springs on mass to suit this set up. This means any kit with heavier rated leaf springs at standard height will probably be much more expensive than a lifted leaf spring.
