Lifting a Kei Truck: The UK Owner's Guide

A lifted kei truck clears the ruts, swallows bigger tyres and looks every bit the little overlander. It is also one of the cheapest, most satisfying jobs you can do to a 660cc mini truck. Here is how a lift actually works, how much you really need, and how to keep it legal and driving well on this side of the world.

Why bother lifting one?

Three reasons, in order of how often we hear them:

• Ground clearance. Standard kei trucks sit low. An inch or two lifts the belly, the diff and the exhaust up out of the ruts on a green lane.
• Tyre room. A lift is what lets you fit chunkier all-terrain tyres without them rubbing the arches on full lock or over a bump.
• Stance. Be honest — it also just looks the business.

One caveat before you start: a kei truck is light, narrow and tall for its width. Lift it too far and you raise the centre of gravity, steepen the driveshaft angles and take the edge off the handling. More is not always better.

How much lift do you actually need?

For almost everyone, 30–50mm (roughly one to two inches) is the sweet spot. That is enough to clear a set of 12-inch all-terrains and lift the underside over the worst of a rutted lane, without wrecking the geometry or the ride.

Go much beyond that and you start needing extended brake lines, corrected driveshaft angles and relocated bump stops — more money, more faff, and a truck that drives worse on the road for not much extra capability off it. Our kits are built around that two-inch mark on purpose.

How a kei lift works

Kei trucks split into two camps at each end:

Front — coil sprung. Most modern kei trucks (the Suzuki Carry DA63T/DA16T, the current Daihatsu Hijet) use coil springs or struts up front. You lift them with spacers that sit on top of the strut, or with slightly taller spacer coils. Bolt-on, no welding.

Rear — leaf sprung. The back end usually runs leaf springs. You lift it with blocks between the axle and the leaf pack, or with longer shackles, or by adding a leaf. Blocks are the simplest and what most kits use.

If your truck is 4WD, keep the lift modest — the front driveshafts only like so much angle before the CV joints complain. Check your brake lines and bump stops have enough slack too. None of this is hard; it is a weekend job with hand tools.

Keeping it road-legal in the UK

This is where a Japanese lift guide is no use to you — their rules are not ours. A few things to get right for the UK:

• Re-aim your headlights. Lifting the front changes the beam angle. It is an MOT item, so set it after the lift.
• Check your tracking and geometry. A lift shifts the alignment. Get it tracked afterwards or it will chew the inside edges off your new tyres.
• Mind the arches. Tyres should not poke beyond the bodywork or foul the wings — both are MOT failures, and you may need mudguarding if they sit proud.
• Your speedo will read optimistically once you fit bigger tyres (more on that below).
• Tell your insurer. A lift and bigger wheels are modifications, and they must be declared — don't find that out the hard way after a claim.

Treat this as a practical starting point, not legal gospel. MOT and DVSA rules change, so check the current guidance and have a chat with your insurer before you commit.

Tyres and clearance

A lift and a set of all-terrain tyres in the kei-standard 145/80 R12 is the single biggest transformation you can make to a green-laning kei truck — grip where the road tyres just spin.

If the new tyres sit a touch close to the suspension after a lift, a pair of 20mm wheel spacers pushes the track out and clears them. And while you are speccing the build, a set of recovery traction boards is cheap insurance for when 660cc and 4WD still isn't quite enough.

What we fit

We stock bolt-on two-inch lift kits sized for the two trucks we get asked about most:

• 2-inch lift kit — Suzuki Carry DA63T — the classic first overland mod for the most popular kei truck in the UK.
• 2-inch lift kit — Daihatsu Hijet S500P — square stance, room for A/Ts, on the current-shape Hijet.

Both are a bolt-on weekend job. Pair one with a set of A/Ts and you have a proper little trail truck.

The bottom line

Two inches, a set of all-terrains, headlights re-aimed and the geometry checked — that is 90% of kei trucks sorted for the lanes, without spoiling them on the road. Start there.
