I do agree it is pre savage x though because the trans is not the easy access, and neither are the diff housings. I would really suggest buying the new diff housings/bulkheads while you have the truck apart. They make diff maintenance very easy, as opposed to the older ones where it's a nightmare to service the diffs.

All parts from savage 21 to the new 2013 savage x 4.6 super duper are interchangeable. It gets tricky with the flux and xl, because they have beefier parts... I.e axles, driveshafts, diffs.

Than you got a 21 with the .25 in it, very soon after the 25 was announced, the trucks were released with 4 gear.. You must have gotten a very early production 25.

I bought the truck brand new.

Check my updated reply, the Savage 25 came with a 2 gear according to hpi...and I think they know their stuff.

According to the SS 4.6 page the 25 had 2 gear diffs.

The Savage Limited Edition was the first RTR to get the 4 gear diffs. The 25 RTR never got them. It took about two years for that edition to come out.

My 25 rtr had 4 gear.

Good to know parts are interchangeable. That was going to be my next question for sure. I do plan to get the beefier diffs for sure. Diff maintenance sucks enough without other headaches.

My 25 had 2 gear diffs but almost all the hardware is allen screws. Maybe someone changed it ?

My flux is about 90% Phillips course thread. Savages have always been mostly Phillips drive hardware

I didn't know that . See you learn something new every day.

Interesting, I don't remember them getting that update. TIL.

hotrod, were your screws stainless? RC Screwz sells/sold a full kit for the Savage.

That radio box totally threw me off the scent. All you need to do though is go to http://www.savage-central.com/ for confirmation of any misconceptions. They have Savvy's down pat.
