AAL+Shock Question

Im planning to install a 2" ALL in the rear. Do I need to upgrade the stock shocks on my 2015 TRD Off Road? Im not sure but I think the stock shocks are Bilstein 4600? I also already have a 2" spacer in the front.

 

From what little I know is that IF you're not wheeling on trails where your truck will be flexing to the limit, you should be fine. It has to do with the rear shocks topping out and blowing the shock. I recently did an AAL and kept the stock shocks that I got from a 2019. Also picked up the front coil overs from the same 2019 and gained 1.5" up front.

Here's a little bit more of what little I know. The 5100's have about the same travel, unless you get the extended travel ones. Although the extended lenght or travel 5100's are made for 4"+ lifts. Going this route, it's recommended to get taller bump stops to prevent the shock from bottoming out.

Hope this helps, or at least gets the conversation started.
