I have one and love it. I have a 39 Chevy street rod and end up spending time under it keeping it going. The Kwiklift makes oil changes a snap. It also makes it easier to flush the brake lines before taking the Viper to the track.
One slight issue is getting a floor jack that raises the lifting bar high enough to lower to braces. I have a nice lightweight racing jack I bought to change the oil on my Viper because my old floor jack was too high to get under the Viper. When I got my Kwiklift I found that the racing jack wouldn’t go high enough with a single lift to get the braces down. I used wood blocks and made multiple lifts for awhile. This was painful so I broke down and bought a third floor jack from Harbor Freight that has a maximum lift of about 20.5 inches which is enough for a single lift. It however doesn’t go low enough to get under the lifting bar so I have a ½ inch plywood board under the Kwiklift to get it high enough to get the Harbor Freight lift under the lifting bar.
I also bought the ramps to drive up on the Kwiklift. I my judgment, they need to be about twice as wide as they are. Unless you hit them dead on the Kwiklift will slide on the floor as you drive up on it. Some users nail blocks into the floor of their garage to keep the Kwiklift from sliding. I put both of the ramps on one side which doubles the area to drive up on and I made myself a second ramp out of plywood for the other side. By doing this and by having the ½ inch plywood under the Kwiklift I have eliminated the sliding of the lift as I drive up on it. I’m taking my 39 Chevy to the National Street Rod Association event in Knoxville, TN next month and plan on talking to the Kwiklift folks about making their ramps wider. Also they do not power coat the ramps unless you ask for it.
I bought a changing mirror you use on a closet door and mounted it on the wall beside the Kwiklift in order to see the wheels of the car as I drive up on the ramp. This way I don’t need to have my wife to guide me up on the ramp.
I leave one end of the ramp up all the time. You can put both ends of the ramp down and park level however the geometry for the ramps are different and you will need a second set of ramps. I didn’t realize this at first when I looked at the Kwiklift.
The bottom line is that the Kwiklift is great if you have a low garage ceiling and cannot use a four post lift.
