I think the bullshit is charging 600 for a torsion bar and some hardware...
Perfect. It is guys like you that should try to bring a single quality product with a reasonable degree of usefulness to market. Once you do that, you'll never again bitch about the price of anything good.
Forging die for the arms is about 20 grand. Arms in production will cost you 25-30 bucks each pre processed.
5 bucks each for splining in quantities of 3-400
5-6 bucks each for coating
buck per sticker. Amortize the forging die out over 1000 arms and add another 20 each and hope you sell a 1000. If not, the cost per arm is higher.
Machine the pinch bolt hole and slot, with the adjustment holes 4-5 bucks.
That puts your cost for just the arms at 120 bucks per pair.
No one can get that torsion bar done for less than 135 bucks in quantity by the time you buy the chromolly, machine it down to size, spline it with timed splines and drill and tap the ends for the bolts.
Now you're at 255.00.
Links are minimum 8 bucks each.
Rod ends for quality are 30 each
locknuts are 45 cents each in big quantities
Jam nuts are 40 cents each in big quantities.
UHMW bushings for each end of the tube are 10 bucks each.
You're up to 415 now and you've tied up the better part of a 100 grand with no packaging, no dealer profit, and assholes overseas knocking off your shit so the cheapasses in the US will take one for the team.
Just in case you think my numbers are that far off. I just finished up my tail light project with a few extra odds and ends for the next run. I've got 40 grand tied up in that and I'm buying shit 6000 pieces at a time of some stuff to make some of the economies of scale work for me. That's a small run of a couple of hundred pieces.
Go ahead, try to make a product and get it out there for sale, I dare you.
