2.5" rear lift, do i need extended brake lines?

All pavement, currently on 1.5" rear, considering 2.5".

 

Has more to do with the shock travel. We have been using pretty long shocks on our Tacoma and have had no need for extended brake lines. For OEM fit shocks you should be fine

 

I recently put on deaver stage 2 expeditions and 5160s. It's marketed as 2 inches, but I ended up getting closer to 4 at first, then 3 once it settled. I didn't extend the brake lines or get a new carriage bearing. I've wheeled and put the truck through some pretty harsh articulation over the past couple of weeks. No problem with the brake lines.

 

kinda depends on the setup, I've over extended my brake lines with my icon leafs, most likely your shocks will limit the travel anyways.

 

I've seen this asked a few times and searched a little myself but haven't found solid answers. It's really one of those things where you just need to spec it out and see how it goes with your setup.

That said... my take on this is that it stainless steel brake lines are a worthwhile upgrade and while you're doing that you may as well get longer ones. Do it for the brake line upgrade and get extra travel as a bonus.

I just did new front rotors/pads and front/rear stainless brake lines - IMO a "must have" upgrade for these trucks. I used the extended Wheelers rear lines and made a small spacer to shim up the brake line bracket. Now I've got plenty of slack which was tested while installing my AAL.

 

I think it's very important to install some sort of rear brake line extension. Only when longer shocks are installed. Bilstein 5160 comes with a bracket to extend the lines. I normally install this kit below but they are sold out at the moment. Last option would be extended brake lines.
