I was curious if anyone has had any experience using the Quick Jack on a Radical? Im assuming you would need to jack the car up to get ground clearance to slide the quick jack under the chassis.
Thanks!
I built wood ramps and drive over the quick jack. It stay on shop floor
Problem solved, Thank you!
Would you recommend using 2x 6 lumber for the ramps? Is that enough elevation to clear the quick jack?
It also looks like you have a cross member underneath to position the QJ in the correct position just in front of the attachment of the rear diffuser consistently. Thats a great idea!
@schneller I start with a single layer of 2” lumber, then add another 2” on top spaced roughly 3’ from start of ramp for a total of 3” of ramp height. The board for the front tire stop is a 1”x6” Cross member connect to the 2”x6”. The back cross member is not connected. I use it to keep to ramps spaced properly. I remove it so I can slid under the car.
I use quick jacks with mine and do not use any wood at all.
If you use a standard floor jack from the rear jack point, you can jack it up high enough to get the quick jacks where you want them with no wood at all.
I jack the rear up high enough to have the front splitter just make contact with the ground and leave it there while getting the quick jacks into position.....lower the jack with the quick jacks in place, then raise them up.
There is enough clearance under the car for the car to be sitting on the on the ground and still clear them - the issue is sliding them under the side skirts which is why jacking up from the rear is needed.
Thanks Jason, appreciate the feedback. I will give it a try. Do you use any wood or rubber pucks between the car and the QJ to prevent damage?
Yes, I used the rubber pieces that the quick jack comes with.
I think there were two different sizes that shipped with the quick jack - I forget which ones I used.
I use the thickest rubber puck on the rear and a shorter puck on the front due to the rear-heavy weight distribution. I find if I don't do that the car really wants to teeter back. Then when the car is up, taking off the rear wheels helps to balance the car further and sometimes I'll set something on top of the crash box just to be extra careful.
Good info. Appreciate that. I have seen photos of people hanging 25lb weights on the front axles with front wheels off on both sides to accomplish counterbalancing as well
