These comprehensive performance upgrade kits are tailored for GM Silverado/Sierra 1500 pickups from 2023 to 2025. The suspension upgrades feature ADS Racing Shocks Mesa 2.5 Series shocks, which are larger than stock, providing increased fluid capacity to prevent shock fade and deliver exceptional off-road durability combined with commuter comfort. The kits also include a Flowmaster Signature Series Exhaust System, known for its hand-welded 304 stainless steel construction and balanced sound profile, offering an aggressive yet moderate tone. Additionally, each package is equipped with a tuner suited for each model year, including DiabloSport PredatorX, Intune 3, and DFM Module + Amp’d Throttle Boost Kit, all of which provide pre-loaded tunes and customization options for optimal performance. Finally, Big Claw Performance Rotors are included, designed for improved braking performance and enhanced cooling to ensuring safety and reliability during high-performance driving.
