You will need to measure your valve stem well in order to properly determine which length valve to purchase. It is impossible for us to know the length for every wheel application on the market as wheel width, offset, size often changes the depth of the valve stem well. Please CLICK HERE to watch a video that demonstrates how to properly measure.

The 2" - 2.5" lift is right between the 8" and 10.5" autoLYNX size. The determining factor is your front bump-stop length and shock stroke length. If you have at least a 2" bump-stop extension installed in the front, you can/should run the 10.5" version. If you do not have bump-stop extension installed in the front you will need to run the 8" version. 2" bump-stop extensions are common with most lifts that include a 10" or greater travel shock.

8" autoLYNX works w/ 7" - 9.5" travel shocks and no added bump-stops.

10.5" autoLYNX works w/ 9.5" - 13" travel shocks w/ at least 2" front bump-stop extension.
