which landrover shocks fit the 340

Post by **cheshire190e** » 08 Jul 2008 11:44 am

Hi, my rear shocks are in need of a change, i see lot of people saying they have used landrover shocks on the rear.

this should stiffen up the suspension a bit but im not sure which ones i need.

anyone know the ones that will fit?

cheers

Matt

if its the same fitment as 360 then landrover defender 90/110 front shocks are a direct fit, and only £25/£30 new off ebay

Spot on. i have them on my 340, very stiff.

So, if I'm understanding this correctly...these particular shocks fit the rear of a 360 as well??

I keep hearing about this, but do they really fit? - i.e. not just do they fit on the car, but what about piston length with respect to bottoming the suspension out. Also what are the rebound and compression forces of standard defender dampers?

One quick gripe... dampers don't absorb shocks and dampers don't have stiffness

I did always wonder - what are the advantages of fitted Land Rover shocks? Standard Ebay fare isn't exactly expensive - and if it's race spec stuff you need, keep an eye out for some Konis ...

Just to be sure before i part with my cash. are these the shocks i need for the rear of my 340?

indeed

dampers control the rebound AFTER the 'shock.' a bit of a misnomer, it has to be said. the REAL 'shock' absorber is your spring.

hard shocks plus weak spring = f*ked shock.

Its been covered by other threads but for the record, you need to double up your leaf springs if you're serious about this or you'll keep breaking your shocks, landrover or not.

mine are getting doubled up sometime before xmas. slightly after ive stuck the webers on

yay

Erm, and they also control the bound DURING the compression.

Ideally you'd say they provide a force opposing the change in velocity they experience

so what do dampers do then

Stop the spring from bouncing around like a bouncy thing

yes BUT thats not what they're designed to do..

Shocks DO provide resistance to the spring compression, agreed, hence why most people think they actually make the car stiffer. I think of this as more of a by product though, not the reason to put stronger shocks on:

The spring takes the energy out of the initial bounce. in coiling up tight under compression, it stores potential engery which shorty afterwards gets translated into expansion (i.e pushing the car back up again). the 'shock' is actually more of a stabiliser; it is designed to limit the number of times the spring will compress and expand from one bump. at the same time, because of the way they are used, they also serve to reduce the rate at which the spring compresses. if you are relying on the shock for this, however, you're using the wrong springs (or ones that are too weak, anyway).

So:

is actually a lot more accurate

so there

Its a pretty subtle difference.

You can tell when your shocks are knackered by bouncing the car. if it wobbles for ages, they're shagged. If it goes down, then bounces straight back up, with a small hiss, and stays there solid like a rock then they're alllll good.

the real skill (and my 360 is certainly no good example) is in balancing the correct strength of spring (to take the right load weight) with the correct shock absorber. If they work well together, good handling. if not... well, you have to keep replacing them

um..... I'm pretty sure I'm right..... (and chris too - but he mainly does elektrikery so likes to use words like bouncy to describe suspension

)

springs provide a force proportional to displacement and dampers provide a force proportional to the velocity. The amount of force that they provide (and whether it is in rebound or compression) is trivial and simply a scalar value depending on whatever valving and numbers you want when designing the system.... the principle never changes.
