Difference between 08 09 and 10 gen iv vipers

[SRT_BluByU]

What are the differences between 2008, 2009 and 2010 viper convertibles? Anything new added between years?

[J TNT]

2010 had a better 5th gear .and had the lowest production number.

[GTS Dean]

Differentials and yokes.

[SRT_BluByU]

Thought all gen IV's had the same diff dana 44? What changed?

[Steve M]

There are no differences across the Gen 4 lineup when it comes to the differential that I’m aware of.

Steve, there's a thread here that you contributed to about minute differences in stub shaft retainers and the diff construction/operation themselves, IIRC. Might have been G5, but I don't think so.

I'm 99.9% sure the Gen IVs all had the same stub shaft retainers, etc. The Gen Vs were slightly different.

Normally no one would care about something as innocuous as stub shaft/retainers, but since it's a nightmare to remove these on a Gen4 it's very important.

Haha agreed.

When I swapped to 3.55s in my Gen IV ACR, I just swapped for a whole Gen V differential. Much easier, and relatively the same cost at that point.

08's have square wire section snap rings that secure the stubs into the diff. 09-10 went to a round wire section snap ring which improves the chances of removing the stub from the carrier.

It was in the Gen 5 section, specifically this post: https://driveviper.com/forums/thread...l=1#post433200

The important point I was trying to make that there are differences across generations from Gen 3 to Gen 5 that affect compatibility when trying to use parts from a different generation. Within the same generation, however, there are very few if any differences when it comes to the differential. The only exception I can think of off the top of my head is the Gen 5 ACR, which came with a different (finned) rear cover, all else (internals and external mounting points/interfaces) being the exact same as the other Gen 5 variants.

You just have to have the right tool(s) to do the job, all of which I detailed here: https://driveviper.com/forums/thread...n-4-Stub-Axles

I know that it worked on more than my car, because at one point over the past couple of years I sent the tool to someone else, and they were also able to successfully remove their stubs using that method.

08's have square wire section snap rings that secure the stubs into the diff. 09-10 went to a round wire section snap ring which improves the chances of removing the stub from the carrier.

I did not find that to be the case with my '08, and mine was a fairly early build with Gen 3 axles.

The inner snap ring seats/grooves in the stub axles did have a square edge, though, as seen here:



That's something that was addressed in the Gen 5s when they added a bevel to make removal easier. It also helped that the Gen 5 stubs had plenty of places to grab hold of with a puller...the lack of options to grab the Gen 3/4 stubs is what can make them so difficult to remove.

And now to attempt answering your question, I'd direct you to two different threads that have some random info that applies to verts and coupes alike:

Really, the major differences are going to be in the numbers produced, and available color and wheel options (6-spokes became available in 2009).

There were more 2008s (1579 total, 712 of those verts) produced than 2009s (659 total, ~184 of those verts), and more 2009s than 2010s (507 total, ~117 of those verts). Source: https://driveviper.com/forums/thread...uction-Numbers

I covered color options here as best I could find:

https://driveviper.com/forums/thread...or-Paint-Codes

Seems like a change in Federal regulations in 2009 necessitated a change in the frame and side impact beams in the doors, which apparently added some weight.

If you go with a 2008, there's a higher likelihood of having first year production issues. Camshaft position sensors were known to be troublesome (although pretty easy to fix), some of the '08s came with the weaker Gen 3 axles (only important if you plan to race), some of the '08s had random issues with the side glass exploding for no apparent reason (https://www.viperclub.org/vca/thread...indows.619481/), etc.

As a pro for 2008, you can add a standard skip-shift resistor to eliminate the 1-4 forced shift under light load without triggering a trouble code...that was apparently changed in 2009. Otherwise you are stuck needing a custom tune with HPTuners or the Mopar/Prefix/Arrow PCM.

For me, I'd be more concerned with finding the right color with an acceptable amount of mods/miles. Wheels can easily be changed, although the 6-spokes are probably my favorite OEM wheel. If you want something more rare, hold out for a 2009 or 2010, but you might also end up greatly increasing your search time looking for one.

wow - thanks for the links and detailed explanation! Thought I had a good line on an '08 vert today but it had already gotten away...

.. the search continues!

When I started my Viper search, I knew I wanted a Gen4. The information you provided in this single location is everything I would have wanted to help me decide which year. Well Steve M, like all your other comments, postings, or even spreadsheets, Always on point. Thanks
