There is a new Truspeed Sensor for sale at Ebay for $89. http://cgi.ebay.com/ws/eBayISAPI.dll...ADME:B:LC:MT:1 I checked Rocky Mountain Suspensions and they are indeed selling this item for $181.

I have 35" tires with a 6" lift. Do I really need this? I haven't been experiencing any problems so far. The speedo seems to be within the correct range but not right on though.

Thanks...
