The Ram SRT-10 also features a unique oil pan, throttle linkage, new "Hi-Flow" exhaust manifolds, new transmission mounts and a modified Ram Heavy Duty radiator tailored to fit the between the NASCAR inspired grille baffles. The rest of the V-10 is straight from the Viper, with a six main bearing crankshaft with cross-bolted main bearing caps. Despite larger diameter aluminum alloy pistons than the previous generation's 8.0-liter Viper engine, the pistons weigh less and are included along with all-new, lighter and stronger cracked-steel connecting rods.

Cylinder heads on the V-10 are semi-permanent mold (SPM) 356 T6 aluminum alloy. Low-profile die-cast magnesium cylinder head covers feature steel internal baffles and anti-slosh foam. The Viper V-10 boasts a single-piece, central dual-plenum, cast aluminum intake manifold and a single, non-staged two-barrel throttle body for higher peak horsepower RPM. The intake manifold is an all-inclusive Integrated Air and Fuel Module (IAFM) with tubular fuel rails, injectors, sensors, wiring and throttle body. A Ram Heavy Duty cooling system is modified to handle the needs of the new Viper engine. A custom dual exhaust system is mounted to new exhaust manifolds.

The Dodge Ram SRT-10 focuses its power through a new, purpose built Hurst shifter and a modified version of the Viper SRT-10's Tremec T56 six-speed manual transmission. The T56 is fully synchronized with electronic reverse lockout. A new 4.5-inch aluminum driveshaft runs from the Viper-sourced transmission to a Dana 60 rear axle with a 4.11 ratio to deliver the massive torque to the road.

One of the most noticeable exterior features of the Dodge Ram SRT-10 is a unique hood that features a wide power bulge and scoop sitting atop the signature cross-hair grille. “Viper Powered” badges on either side of the hood scoop leave no doubt as to what resides underneath.
