Control Arm Duroflex Joint Alignment...

At MetalCloak we take the care to build every product right.

Most manufacturers build their control arms misaligned from center. Why? It simply costs less to do so.

By not cutting any corners, our joints are Centered and Aligned reducing wear and improving performance.

Best joints on the market November 14, 2018
Reviewer: Jacob Olauson from Alta Loma, CA United States  
Bought this last set so that I now have all MC arms. These joints have been great for the last 4 years on my rig and I expect the new version to be even better. Matson and Jon are always a pleasure to deal with as well.

Great February 6, 2018
Reviewer: Wesley Hunko from Auburn, AL United States  
Duroflex joints are awesome. Only thing I wish were different, is that you have to make a full revolution for adjustment. No half turns, due to the offsets on both ends. Not a big deal though. I’d rather have properly aligned joints than better resolution.

As advertised September 28, 2017
Reviewer: Gabriel Guillen from IMPERIAL, CA United States  
These are heavy duty arms. A big plus is the noticeable ride improvement. Little pricey but I will stick with MC products.
