Shock replacement.

Will Rancho HD rear shocks listed as fitting Prerunner fit my 05 TRD 4x4?

 

1) Welcome to Tacoma World
2) I have NO idea if they will fit. Sorry not much help there. I know Chevy likes Rancho shocks, but I put a set on my wife's yukon and I'm not impressed.
3) I would look at Bilstein, Radflo, OME, Fox for our trucks. I personally run Bilstein and have no complaints on how they ride over factory.

Maybe someone else on this vast community can share. Also, not sure where you are located, but I would find your local forum thread and say Hi. After introducing yourself, I'm sure someone might be able to help you out. Also there are some good vendors on here that can probably answer that like @Crikeymike

 

Yes, PreRunner and 4WD share the same suspension.

 

Yeah, the rear ends are the same. Just be careful if they're HD meaning valved heavy for heavy loads. If they are, and if yours is an empty bed, it could ride really bad.
