Quick answer
For JL and JLU 4-door owners, a dedicated rear trunk storage box like the right-side ABS organizer adds structured cargo space without drilling or permanent modification.
Why a dedicated trunk box beats generic bins
A generic plastic tote slides around on the carpet, spills its contents, and takes up floor space you could use for larger gear. A Jeep-specific trunk storage box is shaped to fit the rear side panel, so it stays put and uses dead space behind the wheel well.
The trade-off is that a fixed-shape box only works on the side it was designed for. If you need to reconfigure your cargo area often, a modular soft bag might be more flexible.
Material and finish matter more than you think
ABS plastic is a common choice because it resists cracking in hot interiors and won't rust. A black textured finish helps the box blend with the factory trim rather than looking like an afterthought.
The downside: hard plastic can scuff soft duffels or camping gear. If you carry delicate items, consider lining the box with a non-slip mat.
How to choose your JL trunk storage box
- Check fitment for your exact model year: Most JL-specific boxes fit 2018-2021 models. If you have a 2022 or newer, verify compatibility because interior trim changed slightly.
- Decide between driver and passenger side: The right-side (passenger) box uses space behind the wheel well. Left-side options are rarer. Measure your cargo area if you plan to install two boxes.
- Prefer no-drill installation: Look for boxes that use double-sided tape or simple placement. Drilling into the trim panel is permanent and may affect resale value. If you lease your Jeep or plan to sell it, a no-drill box is the safer choice.
