T Rex Evolution arms?

[SC74]

Just curious if anyone has some experience with the T Rex Evolution arms that allow caster adjustment? This is the route I plan on going with my current street rig and 3.5" SL.

They look well thought out, they are on my list to install.

It is physically impossible to adjust caster in the radius arms on a Bronco 44 without losing pinion u-joint alignment.

Practice saying these words: "cut and turn..."

@jamesroney is right, but….
It depends on your circumstance whether cut and turn is the right answer. If you plan on much 4 wheeling, then front piñon matters. If you are only driving in town, then it does not matter. Even with 15° of piñon, a 1310 can work under slow steady turning. Very much torque or prolonged use and the joint will fail. For me, mine is a show queen with zero off roading in its future. However, even with that fact, if I do another 4x4 I will cut and turn regardless of use just to get the right caster without having use aftermarket “fixes.”

However, to answer your original question: yes, they are excellent arms, very strong, well made, and provide easy caster adjustments. I have them and my driving went from scary, two hands on wheel to smooth, one hand on wheel and able to turn a corner while changing the radio station. Night and day with better caster.

Thank you for your review. This particular Bronco will just be an ice cream getter, no offroad planned for it. I know 35's will fit with 2.5" suspension, but I like the taller look so going 3.5" suspension lift with my 2" BL. I'll pick a set up at the Super Celebration!

From my experience every EB D44 was made slightly different and what caster they give you is a mystery till you get all the new parts on and head to the alignment shop.

For a street Bronco with 3.5" of SL the EVO T rex arm is an excellent choice. Dial in the caster to the sweet spot of great control and no front driveshaft bind. Honestly, driveshaft bind should only be an issue towards full droop of the front end. We have found for the majority of EB owners we have worked with that if you install a long travel high clearance front driveshaft like the ones made at Carolina Driveline you can get the best of both worlds in this configuration.

This one won't see offroad and looking for best drivability. I want to be able to cruise without having to hold 10 and 2 death grip. I was going to run the regular T Rex and then saw these. Carolina Driveline builds all my shafts and this will be no different. I'll pre order a set for Super Cel pick up. Thank you.
