I have no experience with the Thuren SS. I recently replaced my stock stabilizer with the Carli Low Mount SS. Radio at Carli recommended the high mount with the OEM low mount. This was due to running 35x12.50r18 Toyo RT's. He said they tend to pull right. I did not have an issue with pulling to the right, but felt that I was experiencing a little bump steer at highway speeds. Roads are horrible in Dallas. I decided to install the low mount set at 100PSI based on recommendation from Carli. I believe it ships at 150psi. I am going to add the high mount, although not necessary, and see what happens. I could definitely feel the difference after installing the low mount. Compared to OEM, it is worth the money long term IMO. FYI, I believe both Thuren and Carli both use King shocks for SS.
