I'm no longer running the Nordlock washers. They don't work on rotating joints like swaybars.



Torque close to max and use loctite.

Not looking to change bars and their bushing setup looks pretty much the same. Not sure who is running this bar for a comparison?

Their mount does appear wider when you zoom in. Also their rates aren't as stiff so the forces won't be as high on the bushings.

I still have faith in my solution, perhaps i should shave off the grease boss as well per Badmojo's testing.

It's hard to say for sure without having them both in hand. However, assuming they are using the same bushing, both mounts fit inside the "shoulders" of the bushing and therefore they are very similar in width and support. The only question is whether the Hotchkiss mount is stiffer since it has the gussets on either side of its bolt holes. If they're using a wider bushing, then yes the bracket is wider as well as gusseted and therefore it's likely a more durable design. It would be a no-brainer to use this mount on the BMR bar in that case. Maybe someone can take measurements of their Hotchkis bushing and bracket?

Hotchkis rates are stiffer than the BMR by quite a bit. Their bar on its softest setting is 40% stiffer than a 1LE bar (their website continues to be wrong), whereas the BMR is only 6% stiffer at its softest setting.

It seems to me that the way you modified and bracketed the bushing would keep that grease boss from being in contact with the bracket. It was hard to tell from your pics. If it is touching, then I'd shave it down enough to prevent contact. If it's not touching, then I don't think it matters. Even if touching, it's not captured in a hole like the original BMR setup, so it isn't taking any shear loads. Therefore, it's probably not an issue at all, but I'd want to keep it from making any contact at all just to be sure.

How do you know this info on the Hotchkins rates? Honestly if I had to guess, they are probably very close to the same rates. They both use 1.25" tubing and probably the same wall thickness and hole locations.

The stock brackets compress the bushings a decent amount, so I think the grease boss is probably in contact.

Here's a post with direct measurements of the Hotchkis front bar, and here's a thread where BMR themselves tell us the wall thickness of their bar. The outer diameter is the same, and I agree that the lever arm locations are similar. However, the BMR bar has a wall thickness of 0.188" whereas the Hotchkis has 0.239" wall thickness (or maybe it's nominally 0.25" wall thickness?). So that's the reason for the difference.

Good info, but even Ryephile thought the BMR front was stiffer. We can only go off of the numbers they give us, but clearly the Hotchkins is stiffer because of its wall thickness.

Those mounts look just like the Hotchkins mounts. Maybe BMR will take notice...

It appears the AFE front bar is even bigger at 35mm (1-3/8"), but what is the wall thickness? It looks like the ends are welded on both front and rear bars and not just the tubing flattened.

yea they are pretty beefy and not sure on wall thickness i was just posting it to compare to the bmr/hotckis bar mounts



there is also these but the photos suck lol
