Dear Welder Series…four bar bars – do they need jam nuts?

Dear Welder Series…
I have a couple questions about your 4 link kit. With the adjuster just on one end, wouldn’t it be best to just forget the jam nut? With a rubber boot to keep the dirt out, wouldn’t this let the bar “twist” and prevent binding? I’d have thought that the nut would work loose anyway as the adjuster attempted to loosen or tighten when you go over a bump with one wheel.

Also, I assume your adjusters and bars are a mild steel. How do I stop them from rusting after welding? Do you recommend plating? I would paint the bars etc but I’m unsure about the threaded portions.

Thanks
Miles

Dear Miles…
Hi, Miles. For street use, the bushings have enough elasticity to absorb the twist and not loosen the jam nuts. Even lubricated, it’s likely that the threads in the mild steel bars and adjuster studs would wear and either fail or have to be replaced periodically.

Thread the adjusters into the bars without the jam nuts to keep the threads clean, or just mask off the portion of the thread that will go into the bar.

Thanks for your interest in Welder Series parts.
