Thread: Shock absorber tech advice needed - SLS vs Coil

SLS shocks have higher rebound than Coil.

Thanks Tombie.....

So if I have the right grasp on physics because I have increased the pressure within the bags, in essence increasing their own rebound I could go for a shock that has less rebound?!?!?!?! eg a standard coil shock...

Whats you thoughts.......

You need one slower (heavier) on rebound control.

Because the bags compression increases its resistance, however the bag tries to extend due to pressure so more control needed on rebound.

Hey Tombie, so if when you say higher rebound, in your first reply, also means faster then a HD Coil shock should suffice due to it be slower properties.

I'm really looking for a close-ish fix here.... I'd be a lot more critical if it were the front shocks we were discussing...braking 'n all...

Cheers....

what you require is a shock which allows the airspring to more or less compress at its designed rate but which properly damps the airbag's rebound characteristics.

LR spent squillions to get the correct compromise...I'd recommend with stock standard OEM replacements or equivalents in well known brands... if the rebound damping is not what you want, then you can get the rebound valving upgraded by 10-20% for about $30/shock by taking them to a shock absorber reconditioner who can adjust them to your requirements.

Just like to point out ... Microcat shows different rear shockers for pre facelift D2's (prior to VIN 3A) ... for the SLS equiped vehicles, depending on the VIN range, there are 4x different part numbers for rear shocks for these .... but all facelift vehicles from VIN 3A, (coil, ACE or SLS) all appear to use the same shock absorber ... ??

Why would that be ?

Kev..

Koni.

Then you adjust the rebound to suit your load, speed and driving style.
The added bonus is you'll probably never have to replace them.

That's an interesting observation Fluids... Makes me also wonder what's different bewteen the 2, if anything, seeing that all other parts seem to be the same so the physics doesn't change!!!

Microcat...thats the LR parts catalogue as in Land Rover Microcat – November 2009 - Land Rover Technical Blog
