Chevrolet Trailblazer EXT aftermarket parts and performance accessories

Chevrolet Trailblazer EXT Parts & Accessories

The Chevrolet Trailblazer EXT is the extended-wheelbase version of the GMT360 Trailblazer, offering a third row seating option and additional cargo space while sharing the same LS inline-six and V8 drivetrain options. Its longer wheelbase adds stability on-road and opens up additional suspension upgrade possibilities.

Popular Upgrades

Exhaust systems and headers for the 4.2-liter inline-six or 5.3-liter V8 engines are the most popular performance additions. Suspension lift kits specifically calibrated for the EXT's longer wheelbase are available from several manufacturers. Cold air intake systems improve throttle response and add top-end power on both engine options.

What lift kit fits the Trailblazer EXT?

Two-inch and three-inch spacer lifts designed for the GMT360 platform fit the EXT with the same hardware as the standard Trailblazer. The EXT's longer wheelbase means less aggressive pinion angle changes compared to the short-wheelbase model at the same lift height.

What exhaust options work on the Trailblazer EXT?

Cat-back systems designed for the GMT360 Trailblazer are compatible with the EXT when the correct rear section is used to match the longer rear overhang. Confirm your engine variant as the inline-six and V8 use different header and mid-pipe configurations.
