Hi-Lift Jack Mounting on a Whitson Rack
I normally don't carry the hi-lift jack around with me except for longer trips and off road. Before I got the whitson rack I used to clamp the jack in my ski rack. It was a great fit and I never even knew it was on the roof.
I looked at a couple of options for my existing setup and decided I wanted to use as much surface area of the rack as possible to ensure there was little stress placed on it. The tube mounts for mounting on the side looked OK but the rack only has an ~ 1" diameter frame. I just didn't feel the rack should handle that kind of stress with a jack hanging off the side. I think if the tubing diameter was larger I may have gone with a tube mount.
So until I get a rear bumper I decided to mount it inside the rack. Not my favorite location because it does take up valuable real estate for additional storage containers up there. Anyway here goes...
What I bought
Cons
Pros
Modifications Made
I mounted it on the passenger side
Only drawback is the base plate definitely rattles causing it to reverberate throughout the rack. My fix is to remove the base plate and put it in the recovery gear bag

What I bought
- Hi-Lift Jack 4X400 4XRAC Jack Mounting System
- Cost - $33 locally ($38 off of amazon)
Cons
- No way to secure it to the rack.
- The hardware didn't come with any washers or backplates or anything you can use to secure it to a perforated rack.
- It was clearly designed to be mounted to a solid surface such as a bumper. Hardware is lacking!
Pros
- It was inexpensive enough
- easy for me to modify in an afternoon
- Mounting brackets are solid
- Will suffice until I get a new bumper
- Carriage bolts and wing nuts are good
Modifications Made
I could have used washers for each of the bolts but I wanted:- a more even distribution of the weight at the mounting surface
- to use a larger area of the rack to prevent it from getting "pulled through" over time.
- I just didn't think a washer underneath could provide me with the strength I wanted to support the jack
- I used a 1 1/4" flat bar and cut four pieces to size. Next I drilled the necessary holes and shot it with Rustoleum semi-gloss. Done.
I mounted it on the passenger side
- For more weight on that side to compensate for drivers side lean
- More (cough cough) aerodynamic with the top facing forward
Only drawback is the base plate definitely rattles causing it to reverberate throughout the rack. My fix is to remove the base plate and put it in the recovery gear bag
