That is the coil spring on a coil-over shock. By the way, that is a poorly designed front suspension. Easy to build, not work so well. The top arm should be shorter than the lower. The king pin (where the upper and lower a-arms are attached out by the wheel, look it up) should be pointed at the center of the tire patch (where the tire touches the ground).

I wont be making that one then haha but im finding it hard finding any other plans for that type of axle. That suspension in the pic is probably my best bet atm though

Get a copy of "Herb Adams" book titled "Chassis Engineering".
Yes, it is intended for pavement toys but the concepts and principals apply to the dirt.

Keep asking! None of us learned without asking!

Here is the photo you linked to:



I think the "golden part" you're referring to is the spindle. It is the shaft connecting the balljoints at the ends of the upper and lower control arms ("A-arms") that includes a shaft for the wheel to mount/rotate on.

I'm not sure if the photo is playing tricks with my eyes, but it looks like that spindle was mounted upside-down (mounted to the wrong side of the vehicle) because there appears to be negative steering axis inclination.



It also looks like that design has zero caster or provisions for caster adjustment


Also talk to Graham about using rod ends in bending.

I think having equal length a-arms is the least of that suspensions problems. Actually not necessarily a bad thing with long travel.

Do not copy that. You will not be happy with it.
Without caster it will barely be driveable. With too much scrub radius, it will be uncomfortable to drive. These things are easy to build into your design, more difficult to fix after built.
