Callaway Cars · Chevrolet Programs
From the supercharged Corvette C8 to a lifted Silverado RT, Callaway offers a complete range of performance programs across the Chevrolet lineup. All current programs are orderable new through Bobby Crabtree Chevrolet.
Purpose-built GenFour™ twin-screw supercharger pushes the C8 LT2 past Z06 territory. 0–60 in 2.67 sec. 50-state emissions compliant. Full authenticity package included.
RS drops the stance with a level-down suspension. RT lifts 4" with FOX coil-overs and skid plates. SC520 and SC602 add supercharged power. RS and RT can be combined with SC packages.
5th-gen Tahoe (2021+) with GenThree™ TVS R2650 supercharging. Carbon fiber engine bay, branded door sills, chrome badging, and dash plaque standard. All trim levels including the refreshed 2025.
Same GenThree™ upgrade as the Tahoe on the Suburban's long-wheelbase platform. Full family-hauling utility with the output of a muscle car. Available on all trim levels.
SC630 supercharges the 6.2L LT1 to 630 hp. SC750 takes the ZL1's LT4 to 750 hp and 739 lb·ft — 3.2-second 0–60. All 6th-gen Camaros 2016–2024. Direct Conversion available on pre-owned.
The vast majority of Callaway packages are installed right here at Bobby Crabtree Chevrolet. These upgrades maintain full 50-state emissions compliance and do not void any GM or Callaway warranties.
SC supercharger packages require precision installation at Callaway's Connecticut or California facilities. Your vehicle ships to Callaway for final build and returns as a certified, serialized Callaway with full documentation and warranty.
