Update on my leveling and info gathering. 2020 Ram Rebel with bilstein factory running a Motofab dr-2 kit and Rough Country UCAs.
When you are leveling your Rebel you need to consider the fact that you already have 1" of lift from the factory because you have the ORP springs. Also, remember you have the same exact UCAs as non-Rebel and non-ORP trucks. So when you add a 2" or 2.5" leveling kit to your Rebel, you are effectively lifting the truck to 3-3.5" (1" spring plus the 2" from the spacer) on factory UCAs.
Also consider these truck do not have bump stops like a GM would to stop suspension travel. This means your strut is acting as the bump stop. I am not sure if this applies to all Ram trims but for our Rebels, this is the case. My 2014 GMC had a piece of metal welded under the upper control arm to stop the travel, with bigger lifts you cut this off. Our Rebel's don't.
With top hat style spacers, you are lowering the strut and thereby increasing the travel of the suspension (an increase of 1.25-1.75"). This causes a few potential issues.
- At full droop (with the stock UCA), your UCA will likely hit your spring stopping suspension travel. I see this on half the people running the 2" top hats with factory UCAs. This may put a ton of stress on your ball joint potentially cracking the UCA. Remember our UCAs are polymer and are pretty bulky to increase structural integrity. I believe they are 2" from center of balljoint to inside edge of UCA.
- If your UCA doesn't hit your spring, the next thing it may hit is your hard brake line that passes under the rear of the control arm. I'd rather have my UCA hit my spring then my brake line but this is another issue you may run into.
As of right now my unprofessional and based on the dozens of Facebook and Instagram conversations I have had with Rebel folks, here is my conclusion on some options to best level our trucks safely:
- Use a coilover or new strut kit like Fox or Bilstein instead of top hat spacers. This should reduce the massive down travel increase of the spacer and give you the lift you want.
- REPLACE your factory UCAs. With our Rebels its not really a " you should consider replacing them" its more of a "you definitely should replace them." While the angles are relatively tame, the contact issues mentioned above can be avoided with different control arms. You also get the benefit of better ball joint angles.
Here is the brake line I’m talking about:
