I've done a bit more digging and Bilstein come as highly recommended. I can't seem to find any threads about anyone going from a lowered truck to a levelled one though.
Nonetheless, I see that Bilstein do an Ultimate Lift Kit
. Looks like it comes with everything I would need, but at a price... Would one of you mind taking a look to see if I really do need everything in this kit and/or if there is anything which I may be missing coming from a lowered truck?
I understand that this kit will either allow me to level to stock height or lift a further 2"?
