Not sure I'd really agree with any of those points.


I agree with all Mdm mentions having raced them off road, taught in them and worked on them for last 30years


Have seen plenty of Terrafirma shocks not last, even ones with mild use. And while I know it is fashionable on this website to bash all things Britpart, it really is a rather dump take on it.

Bearmch is gone.... some bits you might find as old stock, but claiming they are all easy to get is utter nonesense.

Old Man Emu really depends on what you buy. Their catalogue is HUGE. And things like the shocks Gwy Lewis sells are not what OME actually list for a Defender. Some of the OME kit have been hugely stiff and hard riding in the past for the Defender. Very much likely aimed at overlanders in Oz with every accessory and a heavy roof rack on top.

Iron Man, don't see much of in the UK, although I have one of their bumpers on my Jimny. Kits are often quite generic and usually aimed at the Oz market for GVM upgrades.

Also been around Land Rover's for decades. Thumbs Up


Now thats a far better balanced and reasoned response and would of been better to have posted initially in my view than than the response you did post to Mdm, who had bothered to take the time and try and help the OP. Cheers

Lifting without increasing travel, just means you have less droop in the suspension. And are more likely to lift a wheel and become cross axled. Thus worse off road. I did mention about suspension flex.

If you go stiffer springs this only makes it worse. Other issues can be getting coil bound before full compression or too stiff a spring rate to allow full suspension flex.


Have been in and around doing Land Rover trials and competition all my life. It is very rare that a standard height vehicle will genuinely run out of ground clearance. Even with 100" wheelbase, let alone the 92.9" of a 90.

You can also fit 33"+ tyres on a standard Land Rover. Any bigger and you put the axles/diffs at risk.


Why do you think lifting is a good thing off road? And what have you been doing that stock height has been a restriction?


He already said he didn't want stiff springs as had them, but wanted a lift. Your response to a lift not being beneficial is based on a lift by going HD, which OP specifically said he didnt want.

Out of interest do you have any links to flatdog? Cheers

I have the Britpart 2 inch lift heavy duty springs and suoergaz shocks on the rear of my 130 camper, had them about 18 months, been really good, transformed the handling, for the money they are excellent.

I have britparts gaz shocks on mine currently and they are alright I think but it’s harder to tell how well they actually fully are just on account of how stiff the springs are. I am not sure who’s the springs are, all I know is they are black with various dot colour markings on, with no hint of the maker.

Plus stock springs.

Deep water wading is more than just a snorkel if you do it often though.

That said.... 100% stock standard Ninety bar the roll cage:

The image is impressive and definitely shows off the stock capability for sure. However I feel I’d have a bit of a squeaky bum moment with that! But those are sort of the conditions that round by me do get in when it floods. And because there is pretty much only one way in/out where I live getting out in bad times is one of my priorities (the weather is nice now but come winters it has been worse lately).

Flatdog springs: https://www.flatdoguk.com/def%2D90%2D%2B2%22%2D%2F%2Dstd%7E339

It was in my first reply to the op too. Smile


Any lift with stock length shocks will result in worse off road performance IMO, unless it is just wading. This is as said, due to effectively loosing droop/down travel.

Theoretical situation.

You have 8" of suspension travel. At normal ride height the shock is 50% extended, thus giving you 4" of compression and 4" of droop.

If you lift the vehicle by 2", it will extend the shock beyond 50% extension. In theory you will now have 6" of compression available, but it will leave you with only 2" of droop. What tends to happen is, you will pick wheels up far more often and become cross axled a lot easier.

The extra compression sounds great on paper, but in reality is hard to always utilise. As a stock spring if you have used spacers will have more pre-load on it. A longer spring may have more coils. Both could result in becoming coil bound before full compression is achieved. And if you go for a stiffer spring in any combo of same length with spacers or longer. Then the roll resistance might just too great to compress well. So you could end up with 6" of compression from your new ride height, but only able to utilise 4.5" of it.

Which could mean your total of 8" of suspension travel, is now more like 6.5" after the lift.

In general, fitting a longer shock will overcome the limitation when lifting. But other things will need to be considered, such as retaining the spring or controlling it should it fall out of the upper spring seat.

Really long shocks will also need different mounting locations, else the body of the shock will be too long to allow it to compress without topping out the shock. Longer brake lines may also be needed with more travel. And getting the front end to flex more than stock will take other mods beyond just longer shocks, as the design of the front suspension can limit travel.

A lifted vehicle will be at risk of poor diff pinion angles, which can cause prop vibration and excessive wear. It will also impact the front caster angle.


I'm fully in favour of modded vehicles and even lifting them. But it is worth understanding what is going on and the pros & cons it can yield.

As an example and to demonstrate I'm not just making it all up.

This is my old Series leaf sprung 88. Which I modded. It rode pretty much at stock ride height, but flexed like you wouldn't believe.

This is my current project, the front end flexes better than this, but I had to pick both rear wheels off the ground to get the front to extend further. It sometimes looks tall, but on the rear is running the +2" standard rate Flatdog springs (albeit they are actually front springs for the lower spring rate) and standard RRC/D1 red/white rear springs on the front. So suspension wise it only sits slightly above standard ride height.

And lastly my p38 Range Rover, which currently has a 4" lift on! And doesn't flwex bad for what it is.

However, we have messed about with spacers and different springs over the years. And at trials events I've seen many many setups. As a rule, the vast majority of lifted Land Rovers tend to perform worse than stock ones off road. Unless some additional thought has gone into the setup.


For the op, the easiest and most simple answer is a set of stock springs and some 2" lift spacers (like the ones I linked too form ebay). As you'll retain a mostly stock ride (slightly higher centre of gravity, so maybe a little more lean). But overall should work and improve on stiff HD springs.

Downsides are, they may end up with prop vibrations and need either a prop spacer or better yet some wide angle yoke props.

Personally I'd also be looking at running some longer shocks, to negate the lack of down travel off road. Although you may need longer brake lines too and perhaps dislocation cones on the rear or clamp the spring to the upper seat with large cable tie or jubilee clip/exhaust clamp.

Good shocks can also massively improve ride too. Lots of choice, although I'd personally rate the Britpart Celluar Dynamic shocks at their price point. They can be had in +2" too.

The Celluar Dynamic shocks combined with the long Flatdog springs work well too, but won't give the lift the op is after. So you'd still need to add a spring packer. Either 1" or 2". But the longer spring would mean you wouldn't need dislocation cones or a physical way of retaining the rear spring when used with the longer shocks.

Some different bushes would also improve the ride. Polybush offer 'comfort' grade (the blue ones) bushes. These will be softer than OEM rubber and help improve the ride further.

That’s really good to know. Thanks for that Mr Stick.

I will be getting +2” shocks to accommodate the extra and was also thinking cranked arms.
I had not thought about the prop shaft but just wondered if I were to go down the spacer route what the ideal length/size would be for a 2” lift? I’d do a wide angle one ideally from Gwyn but that’s a bigger investment for another day. I’ll also be changing rubbers too as I think my mine are currently rock hard polys which doesn’t help.

Consider pin pin shocks to utilise the suspension on longer shocks and allow a greater degree of rear axle movement.

You can of course fit shock droppers to keep shock in the middle of its range.

OME have some great products to suit if your looking higher end. It lasts as well, which alot of the other brands seems to struggle to do.

Fit a combination that's balanced springs/shocks/ corner weights against what you will use it for loaded or empty.

CD, your point are valid, but I still disagree that there is jonadvantagebfotting a 2" lift for off road. Your work mainly seems to be trial based where upward travel is not always a priority. In fact as you show droop being the main aim. Add a speed element you want tyres to have room to move, which a 33" on boosts on std suspension doesn't have sufficient of unless you modify body work.

I am pretty open minded with respect to what people use their vehicles for: on road, on road towing, slow off road hard terrain, faster off road hard terrain and gentle off road for terrain and speed variations within that. I think your generalisation of a lift is no benefit is more specific to your end usage rather than off roading with all the different formats that exist. I meant personal links to flatdog? Ie commission, product testing, discounts.

Either way I'll leave it there.

As an aside a vehicle is std guise is already far more capable than most people will use it for. Cheers

If you want a wide angle prop, try these guys: https://www.dandfltd.co.uk/

They will make one the same as Gwyn Lewis ones. I paid £165 all in for one for mine.

If you want to try a spacer, just grab one off ebay. You'll know if you need one, as you'll have vibrations at certain speeds, sometimes hear it as a bit of rumbling sound. Probably try a 15mm one first, then max of 25mm.

For +2" shocks, you don't need to worry about pin to pin for the rear. Regular pin to eye will be fine, using stock shock mounts. I would be tempted to fit extended brake lines though, as that is one thing you don't want to stretch and break while driving the vehicle.

Something like this: https://llama4x4.com/product/land-rover-re...raid-blue/

In reality, you won't need cranked arms. But they are an option if you want to spend the money.

You might want to look at correcting the castor on the front axle. Several options for this, most go for castor correct arms. This is probably a better solution though:
https://www.lrparts.net/da3203-castor-corr...umber.html

But you'd have to check if they would work on your axle.

Bush wise: https://www.polybush.co.uk/product-categor...85444af42e

Select the comfort grade (blue). SuperPro are meant to be good too, but I've not used them myself. The Polybush ones are good though.
