Callaway SC602 Package Equipment
GenThree™ TVS R2650 Supercharger System
with TripleCooled™ Intercooling
Callaway’s patented GenThree™ TVS 2650 supercharger provides 602 horsepower and 560 lb-ft of torque, 182 hp and 100 lb-ft more than stock. Fuel mileage is practically unchanged from stock as the supercharger’s internal bypass mechanism diverts the inlet air flow path during idle, low-load cruising, and deceleration, allowing the supercharger rotors to spin freely. Plus, Callaway’s patented TripleCooled™ intercooler system employs three high-flow heat exchanger elements to reduce inlet air temperature, eliminating power loss typically encountered with supercharged vehicles during aggressive driving.

Callaway Carbon Mid-Engine Covers with SC602 Emblems
The supercharger is flanked by matte Callaway Carbon mid-engine covers which conceal coil packs, engine wiring and plumbing. The covers also serve to suppress valvetrain and fuel injector noise. The covers are produced in-house from high quality carbon fiber and finished in a matte clearcoat.
High-Flow Intake System
The high-flow Callaway intake system includes a specifically configured inlet duct and low-restriction filter element to supply the supercharger with the extra air volume that it demands.
Low-Restriction Stainless-Steel Dual-Outlet Exhaust System with Quad Tips
The low-restriction Callaway exhaust system allows increased gas flow for more power and provides Callaway’s authoritative, yet unobtrusive “signature tone”. The acoustic chamber design creates a unique exhaust note; refined and mature. Internal chamber design and tube construction provide natural frequency-cancellation that otherwise creates in-cabin resonance/droning. Full T304 Stainless Steel construction, CAD-designed, with dual outlets featuring Callaway’s quad exhaust tip design.
CalCal – Callaway Bespoke Engine Control Components and Calibration
Callaway’s “CalCal” engine control components and electronic powertrain calibration integrate the Callaway components flawlessly, ensuring perfect drivability, 50-state emissions compliance and unconstrained warranty retention.

Black Chrome PVD Wheel Finish
A black chrome coating is applied by Physical Vapor Deposition (PVD), producing the unique appearance of a dark chrome plating, without the traditional plating process challenges. It is finished in a protective clearcoat, and should be taken care of like a painted wheel.
Callaway Raised Suspension Leveling Package
Raising the front of the truck to closely match the factory rear ride height offers a leveled, bold appearance without compromising ride quality or load capacities.
Callaway Lowered Suspension Leveling Package
Lowering the rear of the truck to closely match the factory front ride height produces a more sporty appearance and improved handling, as the vehicle’s center of gravity is slightly lowered. This does not affect the vehicle’s ride quality or load capacities.
Callaway Rough Terrain Suspension System
For those looking for more off-road capability, Callaway and FOX have partnered to offer a 4” suspension lift, accompanied by longer travel, lightweight shock absorbers. Both front (coil-over) and rear dampers feature remote aluminum reservoirs with easily accessible knobs for both high and low speed adjustments. The OE rear leaf springs are retained. Included are the Callaway 20” 9-spoke alloy wheels and 35” diameter mud or all-terrain tires. Steel skid plates protect the front differential and underbody components.
