Hairpin radius rods - Youngster's Plans

[all-world1]

In Ron Young's Plans, his parts list include 1 set of 36" radius rods and 1 set of 27" radius rods, which I purchased from Speedway. He starts out with the 36" hairpin setup for the front axle, and I'm assuming the 27 inchers are for the rear. If the 27s are workable, great for me, but they seem short in comparison with other builders. Comments welcomed.

I'm using 27" on the front with a spring-behind tube axle. Works fine for me.

What about the rear hairpins?

Rears are also 27", with added gussets to resist torque from the rear axle.

Perfect, just what I hoped to hear. Thank you sir!

On the rear hairpins, I would add a brace about in the center if you are going to going to put a lot of torque to the rear tires. The have been known to twist enough to bend the two rods together.

The brace for the rear needs to be more twords the center in my opinion. The rear ya bolted to the axle bracket so that serves as a brace.
