A third-generation Montero rides on coil springs at all four corners, so a lift here is a spring decision before it is anything else. The specialist that supplies this generation sells its springs in two raised-height classes and in duty bands, and the two are independent: height is how far the body sits off the axles, duty is how much permanent weight the spring was chosen to carry. What makes that second axis usable is that the supplier states each band as a *range of added constant weight* and names the accessories it expects in each one — which is how you find your band without owning a scale. All of those figures, and the caveat that even a difference in factory trim moves which spring suits a given truck, are in the first citation. Spacers are the other half of the story and the half that gets oversold: the same supplier publishes what a thin strut-top spacer actually adds, and warns in the same breath about what a large one does to the suspension's arc.

What it needs first

Nothing else has to be done first.

What it breaks or affects

Everything below is a consequence of fitting this, not a reason against it. Read it before you buy, not after.

System	Consequence	What happens
Steering	Has to be reset	Changing ride height changes camber, caster and toe. The supplier states outright that a wheel alignment is required after installing its strut-top spacers; treat that as the floor rather than the ceiling, because a full spring change moves the same angles further. An out-of-spec alignment eats tires and steers badly long before it looks wrong.
Suspension	Has to be reset	Height and duty are two separate classifications on the same spring, and the supplier publishes the duty bands as ranges of added constant weight with the accessories it expects in each — so the way to choose is to total up what the truck permanently carries and find the band, not to guess from the badge on the tailgate. It also states a margin of added constant weight above its own table below which it will not recommend the tallest springs for the lighter 2001-2002 trim.
Suspension	Gets worse	A spacer relocates the whole suspension arc while leaving the spring and the damper exactly as they were. The supplier warns that large spacer lifts change that arc and can bring the upper control arm into the shock absorber at full droop. The Spanish-language shop cited below adds the same point from the other side — though note that the specific line about lost travel is that shop reporting a magazine's test on a different vehicle, not its own measurement on a Montero.
Suspension	Has to be reset	The spring supplier names the damper families these springs are meant to run with. A new spring rate under tired factory dampers is how a lifted truck ends up wallowing worse than the standard one it replaced — the spring is now controlling less of the movement, not more.

The honest tradeoffs

You are buying height and paying for it in geometry. The supplier tells you to have a wheel alignment done after fitting its strut-top spacers, and the same logic reaches any change that moves ride height — it is worth budgeting as a recurring cost every time you change the setup rather than as a one-off. Springs chosen for a bare truck sag again the day you bolt on a bumper, a winch, a second battery and a drawer, which is exactly why the supplier's bands are written in added constant weight: the duty rating is a decision about the truck you are going to have rather than the one in your driveway, and choosing it too heavy leaves the empty truck riding like a cart while choosing it too light puts you back where you started with more height to make it worse. Spacers are cheap and reversible, and that is precisely why they get over-used: a spacer does not touch the spring, so the articulation, the comfort and the load capacity are the ones you already had — the Spanish-language shop cited below says so in its own words, and separately reports a magazine test (run on a different vehicle) whose listed downside is that spacers fitted without new dampers leave less travel than before. Dampers are part of the kit and not an afterthought; the supplier names the families it expects these springs to run with. Finally, ride height is not a private decision — it changes what a roadworthiness inspection will accept, and which inspection depends on where the truck lives: the RTV in Costa Rica, the MOT in the United Kingdom, the ADRs in Australia. Those rules are set there, not on this page. Suspension is safety-critical work: have the alignment done and the suspension fasteners torqued by a qualified mechanic.
