What a difference a year makes. Twelve months ago, the fastest ram on Earth was RHO. Ram’s Hurricane-powered off-roader came with all the goodies of the old TRX except two – a Hemi V8 and a name from the Cretaceous period. At the time we were told that the “TRX” would never grace a truck without a Hemi. After all, there was almost 48 months of tradition behind the nameplate.
In the same year, Ram went from a light-duty lineup completely devoid of V8s to one with three of them, and each 1500 would be available in nearly every flavor. And that means the TRX is about to meet its match – not in the form of an updated Ford F-150 Raptor R or some of GM’s new super-trucks, but from within its own showroom. Yes, I’m looking at you, Rumble B.
So, in the battle of the ultimate SRT-powered pickups, which one is really the top dog? Well, it all depends on what you plan to do with it. The 2027 Ram TRX SRT and SRT Rumble Bee Hellcat are actually powered by the same supercharged, 777-horsepower Hemi V8, but the wrappers around those monster engines are quite different.

If you tell TRX Drive to go pound sand, they may not absorb your message properly. After all, the TRX is built to do just that, ruthlessly. It’s equipped with off-road tires, comes with more standard ground clearance, and has trail-friendly Bilstein adaptive dampers designed to keep the body under control over rough terrain. It also has a locking rear diff, which is useful when encountering uneven/technical terrain.
The Rumble B, on the other hand, is designed to go fast on pavement. The wheelbase is more than a foot shorter (in line with the rest of the truck), so there’s less weight to move around and the truck should change direction more quickly. It also sits low to the ground, with minimum ground clearance of just 8.1 inches, and the suspension will also be quite stiff. The Rumble B also gets a limited-slip rear differential, which is better than on-road locker and helps put down power more effectively when there is inconsistent traction at the rear.
You can see how things shake out from the numbers in the table above; Items with differences are bolded.
The other big difference between these two trucks? You can order the TRX now (for the reduced price of just $102,790); If you want the Rumble Bee, you’ll have to wait until later this year to bring it home.
