Hi all, long time no post. Just added data for the Toughdog BM401118 rear shock, which is a long travel option for the Prado 120, utilising the 120 bushing and smaller top pin when compared to the BM401111 which is more suited to the 150.
This rear shock may be of particular interest to Grande owners looking to be able to dial out the high rebound common to most 80 series valved rear shocks. These adjustable shocks change the rebound rate by around 90% while only changing the compression by 10%. I have found that a high rebound is not always desirable with pneumatic suspension unless you are carrying heavy rear loads. Under some circumstances and when lightly laden, the VSC can trigger if the suspension is too restricted in rebound after sudden compression.
Also note that while the closed length of 380mm seems high, it is still shorter than the 386mm closed length of the standard Toyota TEMS shock:

Hey amts,
I finally have some strut, shock and coil dimensions from TJM.
Front strut XGS Gold 659GE188L 420-560mm
Front coil 770FR88I 375mm/565lb/in
Rear shock XGS Gold 650GE288L 375-600mm
Rear coil 770RR88I 390mm/260lb/in
TJM tell me that this is 120 running gear. They also suggested 10mm maximum coil seat spacer.
For the 150, TJM use the new 4000 series struts/shocks (which are just a 15mm longer shaft), but use the same 120 spec coils above;
Front strut 4000 series XS188L 435-575mm
Rear shock 4000 series XS288L 390-615mm
I believe the TJM coils are made by King.

Edit: TJM head office provided incorrect figures above.
These have now been corrected;

Suspension droop was not invented by PP!
Just google suspension droop.

Has anyone installed the OME 2885 (coils) and 90000 (struts) and 60004 (shocks) in their Grande? I'm looking at upgrading at the moment from the TEMS to OME with factory airbags and amts airbag spacer, which if OME's site is correct, will provide me with a c.25mm front and c.40mm rear lift against the standard TEMS. However when looking at the open length for both the front strut and rear shock against the factory there is minimal difference ie.
Factory TEMS (vice versa GXL)
Open 540(f) 575(r)
Close 420(f) 386(f)
Travel 120(f) 189(r)
OME Sport Nitro
Open 543(f) 580(r)
Close 413(f) 356 (r)
Travel 130(f) 224(r)
Difference OME:TEMS
open +3(f) +5(r)
closed -7(f) -30(r)
travel -10(f) -35(r)
Considering this, it seems that I'll be replacing factory gear with OME which is essentially the same length? I called ARB and they've confirmed that the measurements are correct, and that the additional height is achieved from the springs (versus shock length). ARB say that the resting height is higher than factory and they don't have any issues with topping or bottoming out (even with the significantly less travel ....) This doesn't seem right? Has anyone else installed similar or have any differing measurements for the OME open position?
Any all feedback welcome!

Whilst waiting for AMTS and Whitey to come along I'll say that those measurements from the 9000 strut aren't correct.
They should read Open 570, Closed 440 with 130 of travel. I recall it having somthing to do with how they were originally incorrectly measured.
Rest assured the 9000 strut is more that up to the task of controlling the front of a 120, combined with up to 50mm lift they're a great strut.Cheers

Hey,
I don't believe the lengths are correct. There's a few issues, i) the shroud on OME struts is mounted much lower than the bush flange, ii) the newer 90000 series strut is used to describe a few different old strut part numbers, and iii) the revised 90000 series strut uses shorter lengths (I believe).
The old strut part code for the 120 used to be N140S, and the open length quoted in the catalogue used to be 543mm, but this was incorrect and measured to the shroud rather than the bottom bush washer on the shaft flange. The real open length was 570mm, as reflected in the 100mm of droop that you could get running this strut under 2" of lift.
This should have been corrected by the 2015 catalogue, as the correct lengths were emailed to ARB head office by an ARB sales rep...he did it in front of my eyeballs. However, having just perused the 2015 catalogue, I see that the error is still there.
All of that being so, I suspect the latest incarnation of the 90000 series strut is in fact a lower open length than its N140S predecessor.
ARB have changed their policy with respect to long open length struts...also the reason the BP51 gear is all short travel. They are being cautious about CV's these days.
Unfortunately I'm away, and I don't have access to an ARB store to check the latest 90000 strut lengths.
Hopefully someone else with the latest 90000 series strut can chime in and help out with some measurements!

Hey Peter,
Cripes, 5 years that's been sitting around already, I wonder how many years beforehand as well?
Kinda silly that ARB don't fix this, as some after market sellers base their strut lengths off the 543mm open length and sell them as 3" lift kits!
