Hey guys,
I wanted to revive this as I'm looking for something slightly taller myself.
Toytec currently makes a bottom plate spacer for the Baja TX front Bilstein that yields approx. 1" of additional lift but will make the ride a bit firmer. The TX Baja shares the same shock body as the TRD Pro, with different spring rates and valving. This might be the best way to get the original post-production TRD Pro lift before they omitted the third adjustment point. It's pictured on the right below. It will affect the ride height as it preloads the spring, but it won't be detrimental as the pre-production TRD Pro was just as high. The left is what the TRD Pro comes with (except pictured on the TX Baja).
Another option for a very mild lift would be to install a 1/2 Toytec top plate spacer which yields about 3/4" lift. The top plate spacers are reported to not change any ride qualities which may benefit those looking to retain factory ride feel but want a better lift. Of the two, these will work the best as it won't affect the spring preload.
I'm currently looking into a custom front spring at near-factory spring rates without relying on spacers for a lift. I'm afraid the Toytec 620lbs (yielding a 2.5" lift) may be a little firm for me. I believe the TRD spring rate may be closer to 550lb but have no way of verifying without sending it out for analysis or having access to measuring equipment. I'm investigating whether a taller spring with OEM TRD spring rates may yield a higher lift without sacrificing ride quality or having to run spacers.
Unfortunately I have to dedicate some downtown for this as it means obtaining the non compressed free height of the spring. If someone has beaten me to the punch please feel free to share your data so I don't have to.
Rear spring options are pretty much good to go as there are a number of different options (SAW 1.5, Icon 2.0, etc.). Fronts are where we are limited if we want to retain the TRD Bilsteins since most manufacturers are opting to utilize coilovers.
