rear suspension bottoms out

recently purchased an 06 tacoma 4wd access cab and the rear bottoms out.whats the easiest fix. should i add a leaf ? also will the shocks from a TRD model fit and make an improvement thanks

 

Welcome to TW! One of the 2nd gen guy will pop in in a bit and help you out I am sure.

 

i have the TRD OR model and it does the same thing so i dont think taking the shocks off of a trd will do anything. I bought a set of toytec aal for around $80 and it helps with the bottom out but makes the rear end a little harsh. Theres talk of a suspension tsb but i havent looked into it much... maybe i should. Hope i was of some help.
