Can anyone tell me what the difference between the 03-07 4x4 and 08 and up 4x4 steering boxes are? I have seen that Borgeson and PSC both offer a retrofit 03-07 box that uses a new and different Delphi assembly that also requires that a different pitman arm (included) because the sector shaft is larger. I'm just wondering why it is only good up until 07? Makes me think the 08 and up box could be one in the same?

I have the TSB steering linkage kit and pitman arm waiting to be installed on my 03. My steering box is shot and also needs to be replaced. I'm intending on replacing the linkage and box all at once. I'm just wondering if there is a benefit to retrofitting the later box. I can return the pitman arm if the later box requires a different one....

Any body have any experience with the Delphi or 08 and up box as compared to the 03-07 unit?

 

BUMP

Nobody knows?

 

Might want to try contacting PSC to see if they have any info. I imagine the 08 is a stronger unit or a different ratio.
