Fitment, Shipping & Product Support
The Rock Slide Engineering EZ Rack Accessory Tray (SKU AC-TR-107) is the 3/16-inch steel cargo tray that mounts to both plates of the Rock Slide EZ Rack (AC-TR-102S) and functions as a cargo shelf at the top of the spare tire. Powder-coated textured black. 15 lbs. Estimated 30-minute install. Universal fitment — mounts to any size spare tire via the AC-TR-102S EZ Rack plates. Sold as one panel with mounting hardware.
The AC-TR-102S EZ Rack is required for mounting and is NOT included. The AC-TR-107 tray does not mount to the spare tire independently.

EZ Rack System Build Order
The AC-TR-107 is a component in the Rock Slide EZ Rack accessory ecosystem. Build order matters:
| Step | Component | SKU | Function |
|---|---|---|---|
| 1 — Required base | EZ Rack Kit | AC-TR-102S | Two 11-gauge steel plates + 2-inch ratchet strap — mounts to spare tire |
| 2 — This listing | Accessory Tray | AC-TR-107 | 3/16-inch steel cargo shelf — mounts to both EZ Rack plates |
| 3 — Optional add-on | License Plate Panel | AC-TR-109 | Flat panel mounts to AC-TR-107 tray — accepts license plate or Molle attachments |
The AC-TR-102S must be installed first. The AC-TR-107 tray then mounts to both EZ Rack plates. The AC-TR-109 license plate panel is an optional accessory that mounts to the installed tray.
Critical Compatibility
| Configuration | Notes |
|---|---|
| AC-TR-102S EZ Rack | Required — the tray mounts to both EZ Rack plates. Will not install without it. |
| Vehicles without a mounted spare tire | This system mounts to the spare tire via the AC-TR-102S. A mounted spare is required. |
| Rotopax fuel packs | Rock Slide Engineering recommends up to a 2.5-gallon Rotopax pack. Do not exceed the tire carrier's rated weight capacity. |
| Weight capacity | Determined by your tire carrier's rated capacity — not by the tray itself. Verify tire carrier rating before loading. |
Common Questions
Does this tray mount directly to my spare tire? No. The AC-TR-107 tray mounts to both plates of the AC-TR-102S EZ Rack, which is the base system that attaches to the spare tire via a 2-inch ratchet strap. Order AC-TR-102S first, install it on the spare tire, then mount this tray to the installed plates.
What can I carry on this tray? The tray functions as a cargo shelf at the top of the spare tire. Common uses include recovery gear, tools, camping equipment, and Rotopax fuel packs (up to 2.5 gallons recommended). Weight capacity is determined by your specific tire carrier's rating — not by the tray itself. Confirm your tire carrier's capacity before loading.
Can I add a license plate to this tray? Yes — via the AC-TR-109 License Plate Panel, which is a flat panel that mounts to the AC-TR-107 tray and accepts a license plate or Molle attachments. The AC-TR-109 is sold separately.
Does this fit any vehicle or only specific Jeep models? Universal fitment — the AC-TR-107 mounts to any size spare tire via the AC-TR-102S EZ Rack system. It is not vehicle-specific. Any vehicle running a mounted spare tire that can accept the AC-TR-102S ratchet strap mount can use this tray.
The Obsidian Take
The AC-TR-107 is for the builder who already has or is ordering the Rock Slide EZ Rack (AC-TR-102S) and wants a dedicated cargo shelf at the top of the spare tire — 3/16-inch steel, 15 lbs, 30-minute install, powder-coated black. It expands the EZ Rack from a fuel can carrier into a full cargo organization platform.
The single thing to confirm before ordering is that the AC-TR-102S is already installed or arriving with this order. The tray has no independent mounting path to the spare tire.
