Your Defender Even better

The workshop

A part, not an accessory

The Defender was built to be driven, not lived in. Tight cabin, minimal ventilation, a rear door you have to swing wide open in the rain just to reach a saucepan. Anyone who sleeps in one ends up rigging something.

Side Seeker started as one of those rigs — and then as the decision to do it properly: drawn in CAD, sheet laser cut, stainless hardware sized for corrugated tracks, industrial-grade thermolacquering. A kit you fit yourself, onto the frame already on the vehicle, without a body shop.

  1. Stage 01 — Design

    Drawn on the vehicle

    Radii measured straight off a Tdci frame — 70 mm at the top, 50 mm at the bottom — then taken into CAD. No dimension copied from a catalogue: the part follows what is actually on the body.

  2. Stage 02 — Prototype

    Reworked until it shut properly

    Several iterations on hinge position, strut travel, rubber gasket shape and perimeter clearance, until the hatch closed cleanly and the seal held along the full length of the gasket.

  3. Stage 03 — Validation

    Driven before it was sold

    Fitted to a vehicle in regular use and put through rain, track vibration and pressure washing before it went on sale.

it gets used

Every kit is assembled, checked and packed here, by hand. Got a question about your vehicle? The answer comes from the person who drew the part.
