The 2021 Chevrolet Tahoe and 2021 Chevrolet Suburban are arguably the most important vehicles the brand has launched this year. With forward thinking interior technology like an available 15-inch color heads up display, massive rear seat entertainment screens, and visibility cameras everywhere, the Tahoe and Suburban continue to demonstrate why they lead the full size SUV segment. There’s also the addition of the Z71 model as a standalone trim level for those looking to take things deeper into the trails. But there wasn’t much to say in terms of a performance model. However, that changes slightly, as Chevrolet is introducing several bolt-on performance parts for both the 2021 Tahoe and Suburban. Announced ahead of SEMA360, we’ve comprised an extensive list of 2021 Tahoe and Suburban performance accessories that have so-far been confirmed.
Cold Air Intake
The cold air intake announced for the 2021 Chevrolet Tahoe and Suburban is currently being sold with a performance package for the 2021 Cadillac Escalade, but minimal information is given, other than the fact that, yes, it is a cold air intake kit. But, if it’s what’s also offered as a performance accessory for the T1 Chevrolet Silverado, customers can expect power bumps of up to 13 horsepower if/when paired with a cat-back exhaust system. We’ll have more info on this package soon.
Brembo Front Brake Kit
First up is the Brembo front brake kit, which carries the LPO code 5JL, and carries an MSRP of $2,895.00. The performance accessory features Brembo 6-piston, fixed aluminum calipers and larger-than-stock Duralife rotors for an 84% increase in brake pad area, and a 42% increase in rotor area to increase thermal capacity. GM’s Duralife rotors feature a hardened surface, which helps reduce corrosion and provides quieter braking with less vibration, all while returning impressive longevity. According to official testing, the Chevrolet Performance Brake Package provided 31% reduction in pedal force at max deceleration, and 12% reduction in pedal travel, which provides improved pedal feel. As for stopping distance, it should be about the same, but that could change with a set of more performance-oriented tires. Chevrolet made sure that the front brake kit is compatible with 20-inch to 22-inch original equipment or Chevrolet Accessory Wheels. The rear brakes remain the same, but they will be color matched with the fronts. Below are the dimensions of the kit:
Height 12 in
Length 33 in
Width 16.5 in
Weight 100.37 lbs
The greater of either the balance of the vehicle’s bumper to bumper warranty or 12 months / 12,000 miles. The installation kit also comes with an instruction manual.
