Need to go get a 2nd set of 10.9 LCA bolt though. The bolts that come with the Spohn relo brackets are .495" DIA and the stockers are .473" DIA. The Spohns don't fit the "1/2" inch dia hole of the aluminum stock I used for the stepped spacers.

Stock LCA Boxed W/ Energy Suspension Bushings =7.5lbs
(more if your LCA's have the bolts through the holes like my second one does)

Aluminum LCA w/ Spherical QA1 Rod Ends = 2lbs

So I saved a hair over 11lbs, plus it's partially unsprung right? Now they are adjustable, and it was close to half the cost of Spohn units with the same bearings plus WAY lighter.

Wow, they look very nice.
So you have steel ends?
Center section is alum.? 7075 ? 6061 ?
Do you have a drawing of that???
Super job.

Scott,

They are made from 1.125" diameter by .219" wall thickness 6061-T6511 Aluminum. The tubes can be bought from coleman racing (a nascar supplier), they are already threaded, and have the hex peice cut on the end already, then all you need to do , is make the spacers on a lathe, and buy rod-ends.

Man that’s right up my alley,

I could make the whole thing except maybe the end links.
How much do they want for a finished product?
I bet it’s a bunch.

Could make the main tube with titanium, thinner wall,
Maybe not cost effective as the alum is pretty light anyway
The only problem I guess would be there is a certain amount of liability involved if I made them and sold them to some one else.

How much of an improvement in performance will these make when compared to a set of stock ones???
Thanks
Scott

I was reading about these as far as what they will do for you.
They, the article said you can,
Square up your axel
Adjust the pinion angle
Are for road racing, expect a little more road vibration as well
Because they let the rear axle articulate better.

As far as a drag race situation what will these do for you????
Thanks
Scott

Scott, you can't adjust your pinion angle with these.

They don't need to be for road racing necessarily. I made them with the rod ends, because under hard cornering, the factory arms/bushings begin to bind, which starts to lift the inside tire... instead of keeping it planted on the road. The bind also makes things a little more unstable at the edge of traction loss. So they do let the axle "articulate" better.

Plus the cost and weight vs aftermarket was awesome. Cost me $160, vs $$205 for the rod end/poly combo or $245 for the rod end/rod end from spohn and spohns are heavier cause they are steel.

You will get more feedback from the road because they are solid ends.
