Anyone know a part# for that T connection piece?** A: I do not have a part number for you, but I do have a solution. I did the same thing on my truck. I took the tubing to an autoparts store and purchased a barbed brass T fitting that is the right size for the tube. It works very nicely. I also routed the fill tube to the inside of my vehicle and mounted the schrader vavle behind an access panel. No kneeling in the rain or mud to air up or down. **Q: Will these fit my 2019 Toyota 4runner trd off road?** A: Yes they will. You will need to cut off part of the plastic bump cushion that is on the inside of the coil. Only remove what you need to -- leave the topmost portion in place. The bump cushion is an inverted cone of plastic of some kind. **Q: Will this fit a 2019 4Runner trail?** A: It should fit any 5th gen 4Runner. **Q: Have a Toyota 4 runner gen 5 with bilstein 5100 shocks set to max 2" stock spring with corn feed spacers. How much of the bump stop should i remove.?** A: 2” less than the instructions say ## Customer Reviews ### ⭐ Vary low quality *by O***R on 16 February 2022* Missing pieces size is not the same as pic and the product leaking from the valve. ### ⭐⭐⭐⭐⭐ Easy install. *by C***N on 10 August 2020* Fast shipping and easy to install.
