The lift will undoubtedly fit in your garage. The post height is only 84" on the 8000 and 92" on the 8000XLT.
The real question is whether your cars will fit on top of and underneath the lift and that is dependent upon the height of your vehicles and the height of your garage ceiling. Simple math will help here. Add the height of both vehicles together and add another 8" to that. The result must be less than your ceiling height in order for the lift to work in your garage.
(A) Height of vehicle 1- + (B) Height of vehicle 2-
Plus + (C) Track Thickness & Clearance- 8"
Equals = (D) Total height:
(E) Your Ceiling height:
(E) measurement must be equal to or greater than (D) measurement.
Next, the lift will have a maximum clearance underneath of 70" on the 8000 model and 77" on the 8000XLT model when resting on the highest safety lock position. The vehicle you park underneath must be lower than 70" to use the 8000 model or 77" for the XLT model. The vehicle you park on top must be lower than your ceiling height less 74" for the 8000 or 81" for the 8000XLT. (Also, consider the location of your garage door when open and garage door opener if you have one.)
Safety locking positions are spaced at 4 ½ " intervals so if you need to stop the lift at a lower height you may do so.
