2025 RAM 2500/3500 Mega Cab II (DT, facelift 2025) Dimensions, Size & Specs

The curb weight of the 2025 RAM 2500/3500 ranges from 3676 kg (8,103 lbs) to 3720 kg (8,201 lbs) depending on the specific model and equipment. The maximum weight, or gross vehicle weight rating (GVWR), varies between 4491 kg (9,900 lbs) and 5579 kg (12,300 lbs). This high maximum weight allows the truck to carry heavy payloads and tow substantial trailers, making it suitable for demanding commercial and recreational tasks.

The RAM 2500/3500 Mega Cab II offers a substantial luggage or cargo capacity of 1600 liters (approximately 56.5 cubic feet). This capacity reflects the volume available behind the rear seats inside the Mega Cab, enabling the secure transport of tools, equipment, or personal items while maximizing interior space in this heavy-duty pickup.

This truck offers a ride height or ground clearance ranging from 187 mm (7.4 inches) to 217 mm (8.5 inches). Such clearance is ideal for balancing on-road comfort with off-road capability, allowing the RAM 2500/3500 to navigate over rough terrain, obstacles, and uneven surfaces while maintaining stability and managing load under various driving conditions.

The RAM 2500/3500 Mega Cab II is equipped with rim sizes ranging from 8J x 18 inches up to 8J x 20 inches. Tire sizes include 275/70 R18 and 285/60 R20. These larger wheels and wide tires provide enhanced traction, stability, and load-bearing capacity, essential for a heavy-duty pickup truck designed for towing, hauling, and off-road performance.

With a length of 6348 mm (about 20.8 feet), width up to 2120 mm (about 6.95 feet), and height of 2036 mm (around 6.7 feet), the RAM 2500/3500 Mega Cab II is larger than most typical passenger vehicles. Standard single-car garage dimensions often range around 6000 mm (20 feet) in length and 3000 mm (10 feet) wide, but ceiling heights can be restrictive. While the width may fit comfortably, the length could be tight for some garages, and you need to ensure there is ample clearance for doors and maneuvering. Overall, many standard garages might be cramped or insufficient for this Mega Cab model without modifications.

Compared to its predecessor, the 2025 RAM 2500/3500 Mega Cab II shows evolutionary improvements in size and design. While exact previous generation dimensions vary, the new model is generally longer and slightly wider, offering more interior space and ride comfort. The facelift introduces updated styling, improved technology, and enhanced capabilities including payload and towing improvements. Overall, this generation is tuned for greater utility, luxury, and modern features to meet contemporary demands in heavy-duty pickup trucks.

Within the heavy-duty pickup truck category, the RAM 2500/3500 Mega Cab II stands at the upper end in length and height. When compared to rivals like the Ford F-250 Super Duty or Chevrolet Silverado 2500HD Mega Cab variants, the RAM is similar in width but tends to be slightly longer and taller, offering superior interior space, especially in the Mega Cab configuration. Its large dimensions and weight reflect its focus on payload, luxury, and capability, often outmatched only by specialized heavy-duty or commercial variants.

The Mega Cab configuration in the RAM 2500/3500 lineup offers an oversized cabin that provides significantly more passenger space, legroom, and storage than the standard or crew cab variants. Designed for maximum comfort, this configuration is especially beneficial for those who need a work-ready truck with luxury passenger amenities or for families requiring extra space. Its larger interior means it suits users who do both heavy towing and need comfortable transport for multiple passengers.

The 2025 RAM 2500/3500 Mega Cab II offers multiple rim and tire size options, including 8J x 18 inches and 8J x 20 inches rims. Tire options include 275/70 R18 and 285/60 R20. Larger rims with lower-profile tires (like 20-inch rims) offer a more modern appearance and potentially enhanced handling on paved roads. Meanwhile, the 18-inch rims with taller tires provide better cushioning and are generally more durable for off-road or heavy-duty use. Choosing between them depends on user priorities such as appearance, performance, ride comfort, or off-road capability.
