My Harbor Freight lift would only go about 16" in the air so I was a bit short when installing BajaRon's sway bar. Less than $5 and a quick trip to Home Depot for a 2 x 6 for a home built extension. Works great. Shook it pretty good while about 6" off the floor for a test. Here is a drawing of what i made. Held together with 3" long drywall screws.
