The product number and the item image refer to two different part numbers. Found out that the one shown (which is what I wanted) is the FTS8000 item. FTS8008 is a dual anti-roll bar with opposite anti-roll bars.
Anti-roll bar kit 8008 is installed end to end, not end to end as shown in photo. Also, this will only work on a truck with a 5-1/2" Fabtech lift kit, not a standard or 3" lift truck.
