3D MAXpider KAGU Rear Lower Cargo Liner for Tesla Model 3 Highland 2024–2026

The deep lower subtrunk well beneath the main trunk floor of the 2024–2026 Tesla Model 3 Highland is one of the sedan's most practical storage spaces—ideal for stowing mobile charging cables, tire inflators, chilled grocery bags, or wet beach gear out of sight. However, because that recessed well is lined with molded factory felt carpet, a single leaking milk jug, damp charging cord, or sandy wetsuit can leave stubborn odors and stains at the bottom of the compartment. The 3D MAXpider KAGU Rear Lower Cargo Liner (part number M1TL0521309, ASIN B0D3WD9YYS) drops a custom-molded, waterproof three-layer tray into the bottom of that subtrunk well.

Critical Distinction: Lower Subtrunk Well vs. Upper Main Trunk Floor

Before ordering on Amazon, make sure you are selecting the exact trunk zone you want to protect. 3D MAXpider sells two separate rear cargo liners for the 2024–2026 Model 3 Highland:

• This Product — Rear Lower Subtrunk Liner (Part M1TL0521309, ASIN B0D3WD9YYS): A 1-piece tray shaped specifically for the recessed lower storage well underneath the lift-up trunk floor board.
• Sold Separately — Upper Main Trunk Cargo Liner (Part M1TL0701309, ASIN B0CY3PHPD2): Covers the wide upper main cargo deck above the folding floor lid.

Neither product includes the other. If you want complete dual-level rear trunk protection—or matching cabin footwell liners (part L1TL06901509)—you must purchase each piece individually.

Three-Layer KAGU Construction Inside the Subtrunk

Rather than using a thin, floppy plastic sheet, part M1TL0521309 uses the same three-layer KAGU laminate found in 3D MAXpider's cabin and upper-trunk liners:

• Waterproof TPR Top Surface: Features a matte carbon-fiber texture with raised perimeter edges that contain small liquid spills, condensation, and loose grit inside the lower bin.
• XPE Foam Middle Layer: Cushions the bottom of the subtrunk well so heavy metal NACS adapters, portable air compressors, or glass bottles don't thump loudly against the floor pan over bumps.
• MAXpider Anti-Skid Backing: Grips the factory subtrunk felt lining without adhesive strips or damaging spikes.

Compatibility, Maintenance, and Trade-Offs

Verified for the 2024–2026 Tesla Model 3 Highland lower rear trunk well. Because the lower subtrunk is an enclosed recess that sits hidden beneath the hinged trunk floor cover most of the time, this liner is a focused utility upgrade rather than a visual centerpiece.

If you only store dry emergency kits or clean microfiber towels in the subtrunk, the factory felt floor is already adequate. Conversely, if you regularly toss wet mobile connectors, muddy hiking boots, or leaky takeout containers into the lower well, being able to lift out a single molded KAGU tray, rinse it with a hose, and wipe it dry saves considerable cleanup effort.

Final Buying Recommendation

The 3D MAXpider KAGU Rear Lower Cargo Liner (M1TL0521309) is a smart, precision-fit add-on for 2024–2026 Model 3 Highland owners who actively use their lower subtrunk well for damp, dirty, or heavy items—especially when paired with the upper KAGU trunk liner (M1TL0701309).
