Ok, I have gone through all the lift and shock forums regarding the Tundra Bilstein shock upgrades. I have a 99 T4R Limited. I purchased it a couple years ago and it came with upgraded rear springs and a 1" spacer on the front. I'm guessing a 2.5"-3" lift. Not sure why but they left the stock shocks in place. My questions are:

Would it be ok for me to go the Bilstein Tundra shock route on the front or just stay with the T4R spec?

What shocks would I go with on the rear?

There are no labels on the springs and spacers so I'm guessing generic of some type. I have almost 220k on the clock and the stock shocks are getting pretty bad with one leaking.

Thanks in advance!
