    Regular mechanic review

    Basic mechanic, working on regular gas vehicles and trucks first diesel truck I work on is my own. I ordered everything thuren. Set 2 notches back like recommend on the radius arms had toe set to as close as zero possible. Everything looking phenomenal. Couldn’t have asked for a nicer set up. Currently have 33’s. So far so good! Once the 33’s wear down I will upgrade to 37’s! Can’t wait!

    2022 ram 3500 - alien radius arms

    I have everything Thuren offers for the front end of my truck, except for these. I ordered because my wheels were rubbing the stock arms. Shipped and received very quickly as usual. Installed which was also very easy to do if you are mechanically inclined, then had the truck re aligned. Very impressed, I don’t know if it changed the ride quality but it sure feels like it. Thank you again for a wonderful product.

    Awesome Alien Arms

    I was pleasantly surprised to get the Alien Arms for my 2014 Ram 3500 in such a short time as everything these days is back ordered. I was very happy with the quality of the arms and service from Thuren. The installation was straight forward. The Alien Arms look awesome and have had several people want to take a look at them . Thank you Thuren Fabrication. P.S I have the Thuren Track Bar and Sway bar. All three are first rate.

    Thuren FTW

    Amazing craftsmanship, easier install. Took me longer to unpack them out of the boxes than it took to install on the truck. All my trucks will run nothing but thuren products.
