Jacking Rail height - More or less than pinch weld?

[Fly2High]

I have been looking at a set of jacking rails. Some that are out seem to be about 1" in height and will extend down beyond the height of the pinch weld while other are shorter than the pinch weld.

Do you have a preference for the rail height: longer than the pinch weld or shorter?

My thinking is if it extends beyond the pinch weld, you will no longer be able to use the pinch weld to support a jack or stand. You will be forced to use on the rail. My concern is if you have a scissor jack that goes on the pinch weld that you will no longer be able to use it to change out a tire, etc.

If the rail is recessed (shorter) than the pinch weld, how do you get the jack to reside only on the rail and not put pressure on the pinch weld which is what you are trying to protect.

Thoughts????

We designed ours taller so the pinch weld would be protected not only during the jacking process but also speed bumps and other crazy driveway situations.

A lightweight floor jack (with a hockey puck set into the jack's lifting pad).

I like mine a lot (CJR002). They sit just a couple mm below the pinch weld and make working on the car soooooo much easier.

Can you still use the scissor jack to change a tire while the rails are on?

Absolutely. It's easier to use a jack (hydraulic jack, scissor jack) in general.

Jacking rails should still have a sufficient gap between the pinch weld and the rail, probably 1/4". I just installed the Steeda 555-5212 jacking rails. They sit just below the pinch welds. A scissor jack will easily fit in between but why do you want to use one? Your PP2 didn't come with one.

I am purchasing a spare tire for the car. I can get a 135/70R19 spare to fit and it is very close to the stock 305/30R19 tires in diameter. Automotive Authority can get them.

That makes sense now. I was wondering why you were going to use a scissor jack with jacking rails. If the scissor jack is the one I think you are getting, it will not fit once you put the rails on.

So basically, if you want or have a spare tire (with factory or factory like jack), you cannot have jacking rails.

I wonder if you can get a different scissor jack that can lift a flat rail. I have looked at the Torin scissor and it does not have a slot (https://www.amazon.com/Torin-Steel-...1&imprToken=UMo6kBxBce8cdk6laK1sRw&slotNum=19).

I suspect this can lift on the rail. Not sure if it can slip and if a hockey puck might help.

That jack will work. Definitely want to use a hockey puck on it for grip and to protect the jacking rail from damage.

I can't speak for other brands but that jack would work with our full length rails.

I have the bmr low profile jacking rails and they don't cover the whole length of the pinch weld. You should still be able to use the scissor jack near the tires.

I just use the jacking rails to lift the car and place the jack stands on the pinch weld.
