Want to fit a 2inch spring lift kit (spacers) to aid a few of my local pay and play sites.

I intend to leave the SLS intact, but a quick question before I break out the trig and calculate it.
how long does the SLS sensor extension bar need to be?
 
There's no need to break out the trig tables. A full lift kit for the D2 with SLS is available, containing the adapters for both front and rear springs and the adapter plates for the ride height sensors to bring the SLABS ECU back into normal calibration.
For example:-

It might also be worth you having a read of the post by @300bhp/ton about the problems which you might encounter in your quest for altitude:-

Yeah I am getting a Dixon fab one, it doesn't come with the sls sensor adjustment, hence I was asking
 
@Toseland, if you take a look at the ebay advert you'll see two plates with two holes in each. I would sugest that they would be installed securely to the mounting holes where the ride height sensors are currently fitted to the radius arms and the sensors are then fastened to the other end. I would suggest that the distance between the hole centres in the plates is the same as the lift being fitted, in the case of the advert, 40 mm.

That would effectively increase the distance between the old and new mounting points for the ride height sensors by the required amount. Looking at the drawing, I can't see any way that the adapter plate could move or rotate around the mounting bolt used to attach it to the radius arm:-

i cant see how raising the springs 2 inches would give an equal 2inches of movement in the sensors,

even basic calculations suggest that if the arms are half way down the arms, 2inches of lift then the distance moved would be 50%, 1 inch..
 
just went to do some measuring..

880mm approx from centre of the axle to the centre of the bush on the chassis,
480mm approx from the bush to the SLS height sensor.

by my calculations, a 50mm lift will need a 27mm spacer, (50/880*480),
 
You could do it by a "trial and error" type method.
  1. Measure the distance between the sensor mounting hole on the radius arm to a point directly above it on the chassis.
  2. Install your suspension lift blocks.
  3. Re-measure the distance as in 1 above.
  4. The measurement in 3 minus the measurement in 1 should then give you the distance between the holes in the required adapter plates.
At least it will save you having to fry your brain trying to work things out on paper.
 
I lifted my old D1 with spacers. Worked fine. But needed to buy +2” rear shock as the originals topped out and had to refit the rear ARB using tow bar spacers.
