3 inch lift/ shock question

Hey fellas,
A couple months ago I put a 3" lift under my 2010 trd sport, with a 3" front (via the typical 1.5" spacer) and 2 " lift blocks in the rear. Everything is good except the stock rear shocks seem to be maxed out, making speed bumps and such harsh. I was wondering what kind of shocks to replace the stock rear shocks with, or if there is a certain stock preferred by the forum for 3" lifts already in place via lift blocks.

Thanks guys

 

Should I just be able to throw those in, replacing the rear stockers?

 

OP, I would read this thread or call Downsouth Motorsports, some people are having trouble with the 5100's in the rear in a lifted application. There's another shock (can't remember if it's the 5125 or 5150) that works better in lifted applications and allows more downtravel so you don't max out the shock. 5100's would dampen better than stock shocks and may be all you need but if you off road you may want to consider all your options. FWIW, I have a 2" lift in the rear and am very happy with my 5100's, I have not maxed them out but I mostly stay on roads or fairly flat trails.
