Two Loud Ram Street Trucks Are Heading to Auction for Charity
Table of Contents
Ram is bringing together two very different generations of American performance trucks for a charity auction. One is a brand new, supercharged 2027 Ram 1500 Rumble Bee SRT. The other is a Viper powered 2005 Ram SRT 10.
Both trucks have received one off custom designs, and they will be sold together as a package at the 2026 Barrett Jackson Las Vegas auction.
The first retail production 2027 Ram 1500 Rumble Bee SRT and the customised Ram SRT 10 were commissioned by UFC and RealTruck, with support from Ram and Mopar. The full hammer price from the sale will go to Folds of Honor and the UFC Foundation.
That means the winning bidder gets two extremely loud pieces of Ram history while the money goes towards charity. Not a bad way to empty a bank account.
2027 Ram 1500 Rumble Bee SRT Numero Uno Has More Than 900 HP
The star of the auction is the first retail production 2027 Ram 1500 Rumble Bee SRT to leave the assembly line.
In standard form, the Rumble Bee SRT uses a supercharged 6.2 litre HEMI V8 producing 777 horsepower and 680 lb ft of torque. Ram says the production truck can reach 60 mph in 3.4 seconds, complete the quarter mile in 11.6 seconds and hit a targeted top speed of 170 mph.
This particular truck, however, will not remain standard for long.
Mopar Direct Connection adds an upgraded 3.0 litre supercharger, pushing output beyond 900 horsepower. The truck also gets a MagnaFlow stainless steel cat back exhaust.
So yes, 777 horsepower apparently was not considered enough.
Key details of the custom 2027 Ram 1500 Rumble Bee SRT
- Supercharged 6.2 litre HEMI V8
- 777 hp in standard production form
- More than 900 hp with the Direct Connection upgrade
- Upgraded 3.0 litre supercharger
- MagnaFlow stainless steel cat back exhaust
- Molten Red Pearlcoat and Diamond Black Crystal Pearlcoat paint
- Custom Rumble Bee graphics
- Satin black 22 inch wheels
- Flame Red RAM logo
- Flame Red Brembo brake calipers
- One of one interior plaque
Ram has confirmed the Rumble Bee SRT as the flagship of its new muscle truck lineup, which is expected to arrive in the first half of 2027.
The Other Truck Is a 2005 Ram SRT 10 With a Viper V10
The second truck heading to the charity auction takes us back to the original Ram performance truck era.
The Ram SRT 10 arrived in 2004 and became famous for one simple reason. Ram put an 8.3 litre Viper V10 under the hood.
This auction truck is a four door 2005 Ram SRT 10. That model year was selected partly because UFC’s The Ultimate Fighter reality series also debuted in 2005.
The engine produces 500 horsepower, giving this truck plenty of attitude even more than two decades later.
Ram itself describes the old SRT 10 as part of the heritage that inspired the new Rumble Bee muscle truck lineup. The new Rumble Bee SRT represents a modern return to the idea of putting serious muscle car power into a pickup.
A Viper Inspired Makeover for the Ram SRT 10
Mark Trostle, Vice President of Design for Ram, SRT and Mopar, worked with builder ProMotorsports on the redesign of the 2005 Ram SRT 10.
The truck receives a Viper inspired black and yellow graphics package, matching leather upholstery and colour coordinated wheels.
The custom build also includes widebody fender flares designed to visually match the new 2027 Rumble Bee.
RealTruck supplied several accessories for the project, including:
- Running boards
- Tonneau cover
- Husky floor liners
The result is basically a visual bridge between the old Viper truck and the new Rumble Bee SRT. One has an 8.3 litre naturally aspirated V10. The other has a supercharged Hellcat V8 with more than 900 horsepower after modifications. Neither appears interested in being subtle.
Old Ram SRT 10 vs New Ram 1500 Rumble Bee SRT
| Feature | 2005 Ram SRT 10 | Custom 2027 Ram 1500 Rumble Bee SRT |
|---|---|---|
| Engine | 8.3 litre Viper V10 | 6.2 litre supercharged HEMI V8 |
| Standard power | 500 hp | 777 hp |
| Custom power | 500 hp | More than 900 hp |
| Induction | Naturally aspirated | Supercharged |
| Doors | Four door | Quad Cab |
| Special features | Viper inspired custom design | First retail production model, Direct Connection upgrades |
| Auction status | Custom one off build | First off the line one off build |
Ram says the production 2027 Rumble Bee SRT is the most powerful V8 powered production pickup in its class of record claims, with a targeted 170 mph top speed.
The Two Trucks Will Be Sold Together
These are not two separate lots.
The customised 2005 Ram SRT 10 and the first retail production 2027 Ram 1500 Rumble Bee SRT will be sold as one package.
The auction will take place during the 2026 Barrett Jackson Las Vegas event on Friday, September 11.
According to the reported auction details, UFC’s Dana White and Barrett Jackson’s Craig Jackson will be present. The winning bidder will also receive a VIP UFC experience, including the opportunity to accompany Dana White during his octagon walk at a UFC event chosen by the winner.
Where Will the Auction Money Go?
The complete hammer price from the auction will be donated to two charitable organisations:
- Folds of Honor
- UFC Foundation
Folds of Honor provides educational scholarships to the families of fallen or disabled service members and first responders.
Why This Ram Truck Auction Matters
This auction is more than a sale of two modified pickups.
It brings together the original Ram SRT 10, better known as the Viper truck, and the first retail production example of Ram’s new Rumble Bee SRT. The two trucks represent more than 20 years of Ram performance truck history.
The old truck brought a Viper V10 to the pickup world. The new one brings a 777 hp supercharged Hellcat V8, and this specific example pushes beyond 900 hp with Mopar Direct Connection parts.
For collectors, the first off the line status of the 2027 Rumble Bee SRT could be the big attraction. For Ram fans, the pairing of the original Viper truck with its modern muscle truck successor makes this a rather unusual package.
And because both trucks will go under the hammer together for charity, this auction could get expensive very quickly.
