Will '11 bilsteins fit a 07 Tacoma trd

Hi everyone first post. I just bought a 07 Tacoma and it has 77000miles on it and debating changing out the shocks on both front and rear just to be on the safe side. I have a found a great deal on shocks of a 2011 Tacoma but am wondering if they will fit onto a 2007 Tacoma. I talked to dealer and he seams to think they will but just wondering if anyone knows for sure. The truck I bought is American but the shocks are off a Canadian model not sure if that makes a difference. Any help will be appreciated. Or would it be worth it to buy air bags for the rear shocks?

 

Yes they will fit, and do you tow a lot? Air bags would only be good using them while under load.

 

Not towing a lot or that often was just wondering if that would be better than the shocks? The truck creeks a lot when I get in and out so I'm just assuming its the shocks and that they are getting worn out. Is there a way to check to see if they are bad or not. Also is better to do all the shocks at once or just replace the ones that are bad

 

That's just the leaf springs it's normal but if you get nice set up of used shocks. Install them anyways.
