Complete Guide to GM Battery Tray Replacement for 2014-2020 Chevy Silverado 2500 HD & Tahoe
Why the Battery Tray on Your 2014-2020 Silverado 2500 HD or Tahoe Matters
The battery tray does one job: hold a heavy battery perfectly still on a chassis that shakes all day. On the 2014-2020 Chevy Silverado 2500 HD and Tahoe, the auxiliary battery tray faces acid mist, water, mud and winter road salt. Let it go long enough and it rusts through, the battery starts moving, and your electrical system pays the price.
This guide covers GM part 22989633 — the factory auxiliary battery tray. You get the fitment list, the failure signs to watch for, a full installation sequence and the maintenance habits that keep the new tray alive.
Direct replacement: the GM Battery Tray For 14-20 Chevy Silverado 2500 HD Tahoe OEM 22989633 is built to factory specifications and bolts to the original mounting points — no cutting, no shimming.
What Is GM Part 22989633?
Part 22989633 is the official GM battery auxiliary tray. Parts catalogs also list it as "Battery Tray" and "Driver Side Battery Auxiliary Tray". It holds the second battery in a dual-battery setup — not the tray under your primary starting battery.
It is built for these applications:
- 2014-2020 Chevy Silverado 2500 HD models
- 2014-2020 Chevy Tahoe vehicles
- 6.0L secondary battery systems
- 6.6L diesel secondary battery configurations
- Auxiliary battery conventional setups
Because it mirrors the factory part, every hole lines up on the first try. That is the core argument for OEM here: the GM Battery Tray For 14-20 Chevy Silverado 2500 HD Tahoe OEM 22989633 installs exactly the way GM intended.

Quick Summary
Why Battery Trays Fail
Battery trays die slowly, then suddenly. Four failure modes show up again and again on these trucks:
- Corrosion and rust. Battery acid leaks and environmental factors deteriorate the metal year after year.
- Structural weakness. A compromised tray can no longer support the weight of a heavy battery.
- Electrical issues. Corrosion causes poor battery connections and voltage problems.
- Safety hazards. A failing tray may let the battery shift while you are driving.
Inspection interval: check your battery tray every 6-12 months. In areas with harsh winters, road salt accelerates corrosion — cut that interval shorter and look twice.
OEM vs Aftermarket: What You Actually Get
Aftermarket trays look cheaper on the shelf. Here is the point-by-point difference:
| Feature | OEM 22989633 | Generic aftermarket |
|---|---|---|
| Material quality | Factory-grade materials | Variable quality |
| Fitment accuracy | Perfect factory match | May require modification |
| Corrosion resistance | Factory coatings | Inconsistent protection |
| Warranty coverage | Manufacturer backed | Limited or none |
| Installation ease | Direct bolt-on | Potential alignment issues |
A tray holds a live battery over rough roads for years. Factory-grade material, factory coatings and a manufacturer-backed warranty are why OEM 22989633 is the safer pick. Order the GM Battery Tray For 14-20 Chevy Silverado 2500 HD Tahoe OEM 22989633 and the fitment question disappears.
How to Replace the Battery Tray
The swap needs basic hand tools and the same care you would give any battery work. Follow this order:
- Disconnect the negative battery cable first — for safety, always.
- Remove the battery hold-down hardware.
- Lift the battery out carefully.
- Remove the old tray mounting bolts.
- Clean the mounting area thoroughly.
- Install the new GM battery tray.
- Reinstall the battery and secure it properly.
- Reconnect the battery cables.
Step 5 matters more than it looks. Rust flakes and acid residue left under the new tray will attack it from day one, and you will be back under the hood far too soon.
Keep the New Tray From Dying the Same Way
Corrosion is predictable, which makes it preventable. Five habits do most of the work:
- Clean the battery terminals and tray regularly with a baking soda solution.
- Apply anti-corrosion spray or grease to the terminals.
- Check for acid leaks periodically.
- Consider adding drainage holes if the tray has none.
- Apply a protective coating such as POR-15 for enhanced durability.
Check the Cables While You Are In There
Corroded trays and corroded cable ends usually grow together. Once the tray is out, inspect the battery cables for green crust, swelling or damaged insulation. If you run a 5.3L Silverado or Sierra from 2014-2019, the Negative Battery Cable Wire Harness for Chevy Silverado/Sierra 5.3L 2014-2019 US is the matching replacement for a cable that is past saving.
Watch the Charging System Too
Voltage problems rarely travel alone — the battery and alternator work as a pair, and corrosion around the tray area drags both down. If your charging tests come back weak on a Chevrolet Silverado 1500 or 2500 HD, the Alternator for Chevrolet Silverado 1500 Silverado 2500 HD A240-6417N ADR0215 covers both trucks.
