Thread: 4 link or Hairpins

Tweet

Although I'm old fashioned, I have to say the four bar setup allows the axle to arc more properly. As long as you are running fenders you won't see much of them anyway, so that would be my vote.

I would also advise going with a four-bar setup. And if you are using a tubular axle, you cannot run hairpins so a four-bar is you only option.

That statement just is not so!

The stock 1937 Ford V8-60 came with a tubular front axle and used a standard wishbone to locate it. Many other manufacturers also had tubular front axles that were located with means other than the 4-bar setup.

While many believe that it is necessary to run a 4-bar setup when they have selected a tubular front axle because the tubular makeup allows less flex than the typical I-beam front axle, there just isn't that much flexing invloved to warrant making the 4-bar the only option.

I will agree that the parallel 4-bar setup to locate the front axle (whether tubular or I-beam) is superior, it is not the only option.

I guess I should amend my statement to "your could run the original wishbone set up or go IFS." But the main point of my post involved a safety issue with running hairpins with a tubular front axle. It should not be done because there is a risk of breakage.

The four bar gives the least amount of resistance, if set up properly.
