The OEM t-stat is the best designed Viper t-stat I've seen and even they can get stuck.
The Stanton t-stats for Vipers I have seen are not nearly as well built at the OEM units. In fact, I've seen them get stuck in the closed position and the car overheats w-in minutes. On removal, the mechanism is wedged a just a bit sideways and prevents movement. They may have changed the design, but I have not seen it.
The caterpillar t-stat has been used and appears to be better made than the stanton.
BUT- The pics of the Mopar Performance t-stat that Jon B. mentioned appear to have the same stout design as the oem one.
if you replace the t-stat it's good to use lithium (water pump) grease to prevent t-stat depression and you can also drill 2, small and opposing holes in the outer jacket to help pass trapped air.
