Overview
The Defender 110 L663 is one of the most architecturally distinctive vehicles on the road today — its flat-panel bodywork and boxy proportions reward well-chosen exterior additions in a way few SUVs can. Every external upgrade either complements that geometry or fights it. The Victorious Rear Side Splitter is firmly in the former camp.
Designed to follow the factory body lines of the Defender 110's lower rear quarters, these splitters visually extend the profile outward and downward, creating the impression of a wider, planted stance. The high-gloss black finish — deep, reflective, and durable — reads as an intentional OEM-style treatment rather than an afterthought. Moulded from impact-grade ABS with UV-stabilised coating, the surface retains its depth and shine through British winters and summer road trips alike.
Whether you're running a full black pack, combining with a gloss rear diffuser, or simply finishing off a set of gloss wheel arch trims, the rear side splitter is the piece that ties the lower rear of the vehicle together. It's a small addition with a disproportionate visual return — exactly the kind of upgrade Defender owners tend to appreciate most.

Installation Notes
🔧 Difficulty: Easy · Estimated Time: 30–60 minutes · Tools: Basic hand tools or clean cloth
- Thoroughly clean the lower rear quarter panel surface where the splitter will be fitted — remove all wax, grease, and dirt using an isopropyl alcohol wipe for maximum bond adhesion.
- Dry-fit both splitters against the body panels and confirm alignment against factory body lines before committing to final fitment.
- If using supplied adhesive, apply evenly to the rear face of the splitter and press firmly into position, holding for 30–60 seconds. For bolt-on fittings, align mounting points and fasten to specified torque.
- Work from the centre outwards to avoid air pockets or uneven seating along the edge profile.
- Allow adhesive to cure fully (minimum 24 hours) before washing the vehicle or exposing to high-pressure water.
⚠ Note: Professional installation is recommended for best long-term results and optimal body-line alignment. Fitting to vehicles with factory-installed body kits or non-standard rear trim panels may require modification and is not covered under the standard fitment guarantee.
Bold. Glossy. Unmistakably Defender.
The Victorious Rear Side Splitter is the finishing detail your Defender 110's lower rear has been waiting for. Complete your gloss black build with a piece that looks factory-spec and performs like it was always meant to be there.
