Looking for some advice
I am looking for a rear heat exchanger for a 2002 viper that has been stretched to a 136"
I have seen that lots of guys add the Srx exchanger but I am looking for something bigger
I have also seen some that bender and mountain performance sells and also that there is one from a viper mountain
My question is will all of these fit the sled and which is the best to go with ?
Thanks in advance

Are you pipped or stock? I run the stock viper mtn coolers on my stretched 144" vipers and never had a problem. You can mod the big SRX cooler to fit a extension but unless your pipped or running a big bore you will be fine with the mtn cooler. Plus the mtn cooler fits perfect without mods to your extension. The extension will have to be modified to fit a big srx cooler but lots of guys have done it. In fact my new 136 viper has the big srx cooler on a track usa extension (bought that way). I also recommend running the bender opticool head gasket and moving the needles on the viper. You will never run hot or risk a lean burn down with all three of these simple mods.

We are running a 136" extended from 121. The SRX cooler is more than enough. Heck we never had any cooling problems with the plain cross over pipe. To run the srx cooler on a 136 viper, you simply add the extra long hoses. Easy upgrade. Al

It is not piped and no big bore kit
Just have trouble with low snow conditions having the temp light come on so annoying
Want to do something so don't have to worry about it

Had no issues mounting the Srx cooler on my 136' extension project.
Modded the extension to a true 136 instead of the 144.
You can see it in the second post first pic

Looks good. So there is no trouble getting the Srx cooler in the 136 viper ?
Looks like this is probably the way we will head .

What kind of tunnel extension is it?
I run scratchers which is enough but im also putting an SX rear cooler in it right now.

Not sure on the make of tunnel extension, bought the sled already extended
I know that the rails are off a venture so they are solid not 121's ext to the 136

This is looking up at the top of the tunnel. Cut the ends and rotated them and re welded. Pretty simple but i had to pound it in. Next time id weld it in the chassis.
