Which ones did you choose?

Went with the TF147's. More expensive but apparently they don't sell the 128's anymore and these replaced them.

Hi Stej,
So you end up with +2" shocks at the back and standard lenght at the front?
Did you adjust the bump stops as well?

Hi Michalis
+2" all round now and it works a treat. Spent the weekend laning in Wales and the improvement was unreal. The lift along with larger tyres has made all the difference there is so much life left in the old girl yet!
I have not changed the bump stops no. Is this something recommended as I never found an issue while away at the weekend.
Cheers
If the bump stops aren't banging down, then no need to do anything!
Dlad you're all sorted ..

As far as I know you need to adjust the bump stops as the shocks will bottom out (closed length is significantly longer than stock) before the axle hits the bump stop. Hence there is a possibility to kill the shocks if this happens on a big hit.

I agree with Paul D, bump stop change to suit a 2 inch lift is not mandatory. Some shocks may bottom out before the bump stops are contacted - but many don't if they're efficiently designed.
I've run +2 inch Britpart Supergaz, OME Nitrochargers & currently Fox dampers without any concerns or need for extended bumpstops.
Some people choose to fit + 3 inch or greater shocks on a car with only a 2 inch spring lift - presumably on the basis that they might get more travel / traction on suspension droop. With what will now be a much longer damper, there's much more liklihood the dampers can bottom out at full upward travel. In these cases either the set up needs checking at extremes of travel without springs or you need more info about fully open & fully closed damper lengths - for comparison with the standard damper info.

You can see below shock lengths (open/closed):
Factory Front 580/370
Factory SLS Rear 570/360
OME 60024 Front 587/368
OME 60025 Rear 587/368
TF127 (similar to TF146) Front 640/390
TF128 (similar to TF147) Rear 640/390
So yes, difference is small. Very unlikely to bottom out the shock but it's still possible.

Unfortunately, although you can make decision that some dampers are definitely OK because they have a closed length less than standard OE, you can't positively decide some are not OK unless you know how much clearance the standard dampers have when the car is on the bumpstops.
The Fox I'm now using have an open length of 629mm / closed length of 397mm for the front - without any obvious problems at full articulation.
Some competition dampers also have bump stops built in to confuse matters further.
It's also worth saying some vehicle manufactures spec the system to cope with loss of bumpstops. I'm not sure if LR do this, but I know from practical experience there were no banging noises when I lost 1 of my front bumpstops at the beginning of an off-road trial.
