Default Are spindles with springs worth it?

I am restoring a Yerf-Dog one seater and I have to replace both spindles to get the steel rims I want to use to fit. The kart came with spindles that do not have springs on the 5/8" bolts. The kart has no suspension whatsoever and since we are going to be running primarily on flat concrete I am wondering if it is worth the trouble to grind off the old ones and install ones that have the springs.

Well, it's nowhere near as good as having actual suspension, however they do take some of the jolt out of riding.

I agree with this, if anything it might take a little stress off the frame by absorbing some road vibration. Maybe possibly help prevent frame cracks down the road? I don't know. Would make for a good test.

Manco seemed to think they helped if that means anything to you.

If you're going to remove the stock spindles, you might as well go ahead and add the spring ones.

If you're really worried about your keister and its comfort and survival, you can also play around with your tire pressures. But on pavement it's basically moot.

Still a good idea. Lets us know what you decide.

My kids two seater manco has them, and our street is TERRIBLE! In our case, the faster it goes, the more the front "hops" with them, 37mph is topped out, and at full speed I can only handle it because I've been driving for 20+ years, a younger kid probably would have a hard time keeping it under control.

However on dirt, they do seem to help a bit, it rides smoother off-road than my dingo does. And I also agree it may help to reduce some amount of stress on the frame, and softer than a non-springer. If it makes any difference to you, I'm building a custom set for my home-made kart, and they will be taller than any of the ones I've seen for sale, and with a bit softer spring. The manco hardly has "flex" of any sort, I'm 160 pounds and jumping on the front end does nothing to compress the springs, probably why it hops like mad.
