I have the 2006 20,500# chassis with V10. Had Blue Ox factory in Pender, NE install the TT2401 Tiger Trak in April, 2010.
TT2401 $ 472.50
Labor 1 hr 190.00
Total $ 705.56
I have the Spicer Model S110 (Dana 135). Handling was so/so with just the front factory bar, but 100% better with back bar added. Stopped much of the rolling going over holes in the yard where I park and when turning in intersection dips and driveways. Have driven 7,000 miles after the install.
