Need to buy longer rear shock?

It' been almost 3 years since I purchased my 2015 TRD Sport and I have now reached the point where I would like to add some height and bigger tires. I know there are a million threads on this, and trust me, I've been to all of them. My question is - If I go with a 3" front and 2" rear level kit, will I need to get a longer rear shock?

Thanks in advance!

 

If you have a prerunner go with Maxtrac Spindle, Dakar leaf pack, and Fox Shocks with the extended rear shock. It will be a investment but you already bought a 30000 dollar truck.
