I have benefited from many of you as I decided on a route for suspension. I thought I would share my experience as everyone's configuration and use scenario is different. This is more of a shock review than lift. In my case, I stayed with stock tire size (265 KO2 C on TRD SEMA wheels). In terms of additional weight, I have Al RCI skids from engine through transfer case (no fuel skid) and RSG sliders.
I am initially focused on armor, sliders and tires as I don't intend on a larger lift for some time. I was looking for rake reduction and more importantly better handling on and off road with shocks capable of accommodating a future lift. I have driven 200k miles combined on 5100s in a 2003 T4R and a 2006 Tundra. No complaints, but I was encouraged by Eibach reviews reporting more compliance on initial impacts through valving. I installed Eibach Pro Truck Sport shocks front and rear, fronts at + 0.8" with OEM SR5 springs all around.
I have put 600 miles of mixed highway driving on the Eibachs including two-lane mountain roads. No off-road miles as of yet. Too much snow. My expectations were modest. Results are better than expected. My vehicle is easier and more comfortable to drive, period. They are less harsh than the Bilsteins. Body roll and nose dive are less severe (compared to stock) and stability through corners and over road imperfections has improved.
I also think it is important to note variables. Mine is a 2019 with 6000 miles that had wheels and tires changed at 900 miles without a fresh alignment and has been through a season of off-roading last summer. While I didn't notice anything suggesting alignment issues prior to the shock swap, a good alignment (which was done after shock swap) can make a difference in terms of drivability, possibly affecting before and after perceptions.
