Any drop designed in them and can steering arms be welded or bolted? Looks great btw.

Before I go into the details on the uprights I need to explain and showcase the experience I have with welded uprights and how they are built effectively. One of the most important elements to the construction of uprights is the fixture, and how it is built. Below is a picture of a Trophy Truck upright I built about 6 years ago, notice the fixture and main plate they are bolted to, they are all steel.



It is important to use Steel for the construction of your upright welding fixture, you need to combat the movement of your material during the welding process and using steel is the best way to combat this. The fixture will be extremely hot during the welding process and if you were to use aluminum then the fixture will move due to the welding heat. This is why the use of aluminum is not recommended for fixtures when welding is present.




We start with a Precision machined 1.5 inch thick chunk of steel, then machine the correct holes and tap the plate to provide the appropriate support for the fixture top plate. In the second picture above you can see the actual upright fixture bolted to the main block; this provides a very stable and accurate fixture that will not cause issues because it is not machined from aluminum.

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?

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.
