The Chevrolet Avalanche lineup is easiest to read as LS, LT, and LTZ, with Black Diamond LS, LT, and LTZ names used for the 2013 final year. LS is the straightforward utility version, centered on V8 power, seating for up to six, and the signature Midgate cargo wall. LT is the comfort-focused middle trim with leather, heated front seats, automatic climate control, and Bose audio. LTZ is the luxury-leaning top trim, adding heated and cooled perforated-leather seats, navigation, Bose surround sound, a heated steering wheel, and upgraded mirrors.
The Base Model trim level—LS and the final-year Black Diamond LS—is the utility-first Avalanche, keeping the V8 and flexible Midgate layout with a simpler cloth cabin.
Best for: Shoppers who want the Avalanche’s flexible cargo setup and six-seat capacity more than luxury extras.
Highlights
The Mid-Level trim level—LT and the final-year Black Diamond LT—is the comfort sweet spot, pairing the Avalanche’s core utility with a noticeably nicer cabin.
Best for: Daily drivers and families who want leather, heated seats, and upgraded audio without moving to the luxury-focused LTZ.
Highlights
Steps up from Base Model with a five-seat front-bucket layout, leather-appointed heated front seats, dual-zone automatic climate control, and seven-speaker Bose audio.

The late-run trim ladder is LS, LT, and LTZ. LS is the straightforward utility-focused version, LT adds everyday comfort, and LTZ is the luxury-leaning model with the richest cabin equipment.
Black Diamond marks the final-year Avalanche lineup. The LS, LT, and LTZ all received commemorative badging and body-color exterior trim, along with added standard equipment on some versions.
In later years, LT adds a more comfortable five-seat cabin with leather-appointed heated front bucket seats, dual-zone automatic climate control, Bose audio, remote start, and power-adjustable pedals. LS keeps a simpler cloth interior and may seat six.
LT covers the main comfort upgrades, while LTZ goes further with perforated leather, heated and cooled front seats, factory navigation, upgraded Bose surround sound, a heated steering wheel, and more advanced exterior mirrors on later models.
They share the V8 and Midgate layout, but their cabins have different priorities. Later LS models use simpler cloth seating and focus on utility. LTZ adds luxury touches such as perforated leather, cooled front seats, navigation, premium audio, and a heated steering wheel.
LS is the straightforward, utility-first Avalanche. In later years it combines the 5.3-liter V8, Midgate, bed-side storage, cloth seating, Bluetooth, and USB connectivity without the richer cabin equipment found in LT and LTZ.
LT is the comfort-focused middle trim in the late-run lineup. It keeps the same core V8 and flexible cargo setup, then adds leather-appointed heated front seats, automatic climate control, Bose audio, remote start, and power-adjustable pedals.
LTZ is the most luxury-focused late-run Avalanche. It combines the Midgate and truck capability with perforated leather, heated and cooled front seats, navigation, surround-sound audio, a heated steering wheel, and power-folding heated mirrors.
LT is the balanced pick in later lineups. It adds leather-appointed heated seats, automatic climate control, Bose audio, remote start, and easier seat adjustment without moving all the way to LTZ's luxury equipment.
Focus on the LS. Later LS models had cloth front seating with room for up to six people, while the LT and LTZ used front bucket seats and were arranged for five.
LTZ has the fullest cold-weather equipment in later years, including heated front seats and a heated steering wheel. LT also has heated front seats, making it the simpler choice if steering-wheel heat and cooled seats are not priorities.
It depends on the model year. LTZ had a rearview camera in the later lineup, while the camera spread to LT and LS as standard equipment for the final Black Diamond models. Check the individual used truck to confirm.
LTZ is the trim to focus on in later lineups. It pairs factory navigation with Bose Centerpoint surround sound and displays the rearview camera through the navigation screen. LT has a simpler seven-speaker Bose system.
