Seems like such an awesome setup for the money! That being said, I’ve got some concerns that really make me hesitant to jump. Maybe I could still be persuaded, but with my luck they’ll all be out of stock or the price will go up.
My hang up is that I had a discussion with a guy at Bilstein and he said he couldn’t access any specs because OEM stuff is kept pretty well locked up. What he did say is that you could bet with all the money that was invested in the TRD setups for both the FJ Cruiser and 4Runner, there are certainly differences in valving between both kits due to weight differences and other factors. He said the difference most likely isn’t just the valving either. I argued that they look identical down to the reservoir mounts, with the only difference being one coming preassembled with top mounts, but it still didn’t convince him.
Maybe the guy just didn’t know what he was talking about, but I’m still not certain. Toyota seems to normally use the same part numbers for the same parts across different vehicles, so why would they do this differently for the spring and shock part numbers across both kits? At a glance this kit seems to be impossible to beat for the money, but the engineer in me makes it hard to make the decision.
