Fabricated C6 Uprights...

[JasonElvisHeard]

One unique item that The GMR has done is that we matched the stock lower ball joint taper perfectly. We will not disclose the exact taper but we can assure it is not either of the standard 7 or 10 degree tapers. With this being a unique taper we decided to custom machine a reamer that matches the stock taper perfectly to ensure quality fitment with the stock GMR components.




The GMR offers these uprights in two different styles, A stock height unit and a 1 inch drop unit as seen below. The image to the bottom left is a 1″ drop upright with a stock height one to the right. These uprights are designed around the stock caliper mounts and ball joints so they will bolt up to ANY C5/6 brake package along with any arms designed abound the stock uprights. These units are also available with a welded on steering arm for direct stock replacement, both in the 1 inch drop and stock height.



The new GMR fabricated uprights are only slightly heavier than the aluminum stock components with a weight of only 6.9 pounds each compared to the stock 5.8 pounds. The Stiffness to weight ratio of the GMR uprights are drastically better than the stock units at operating temperature (non-ambient temperature).



The GMR Uprights are designed to be universal, from stock replacement hubs to GMR front hubs these uprights will work with any C5/6 package.

Looks damn good! Thanks for the tech info. What about steering arm options?

Any possibility that these or future styles would work with RideTech's Tru-Turn?

You would retain your current steering arm, it would bolt on in the same manor as it currently does on your OEM's Upright.

So basically if you currently have a Scott Mock, DSE, Roadster Shop, Art Morrison, etc. you would simply re-use the one that came with your particular suspension.

Now, IF you happen to have a suspension that utilizes the OEM's Upright WITHOUT the steering arm machined off, then we DO offer a weld on arm to maintain stock C5/6 location.

Thanks, Jay

Travis, At this time we have no plans to produce a fabricated AFX version, but its not to say it will not be on the list of "things to do". We are aware of the need as we have had others request the same do to spindle flex and deflection of the upright section itself.

You may want to look into CPP's Upright offerings. They have a Tall A,F,X 2" drop upright that may work with the TruTurn? It would most certainly solve the deflection issue at a very reasonable price.

Hope this helps.

Thanks, Jay

Nice work on the uprights. Looks to be top notch to match the rest of your parts.

Thanks Greg!

Just FYI.... these suckers go great with our Floater Rearends Oh and dont forget the GMR C5/6 Front Hubs

Just curious on what you would recommend from a coating perspective. I would assume that any mounting surfaces would need to be masked off as to not change the dimension, so any concerns about corrosion in those areas?

Just curious.........

These things look AMAZING

I plan on powdercoating mine and we can mask off where the hub bolts up. Actually a good powdercoater can "dust it off" before he cooks it. After that your favorite penetrating oil on the bare surface and assemble. I prefer Gibbs.

Thanks Donny - - - - Just wondering is all.

I may be chatting with you about some GMR stuff at some point - -- - Lord knows my dreams are much larger than my budget though!
