Another update on Dobinsons MRR

Front: MR59-50700 427-570mm 150 shock. Order with 221 shock bush if fitting to 120.
Rear: MR59-50701 362-605mm 120/150 version length spec changed.

Couldn't get the specs for MR59-60701 confirmed. Dobinsons said it was not suitable. Not sure what's up there...

Change:
Rear: Dobinsons MR59-60701 605 229 376 (Optional rear) 60mm body
Rear: Dobinsons MR59-50701 605 243 362 Length can be ordered to 615mm by trimming internal bumpstop.

60701: This is a wider body shock. The standard Dobinsons MRR for Prado is 50mm diameter (first two letters after the MR59-) I didn't check specifically, but I think this shock is the same length as the 50701 and actually has a standard extended length of 605mm. The length can be ordered to 615mm by having the internal bumpstop trimmed by 10mm.

Add:
Rear: Dobinsons MR59-60682 630 ??? ??? (Optional rear) 60mm body LC100 rear shock.

Hey,

Another update for the database, I have lengths for King Shocks 10 way adjustable OEM replacements;

Front coilover is part 25001-261A, lengths 440-565mm

Rear shock is part 25001-262A, lengths 403-618mm

There is also an 80 series rear shock available, part 25001-257A, lengths 398-650mm.

You can get non-adjustable versions with out the "A" in the part number.

Mark

Updates done.

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:

Toughdog BM401118 open length 620mm closed length 380mm.

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.

Mark

Edit: TJM head office provided incorrect figures above.

These have now been corrected;

659GE188L 420-555mm (120 strut)
XS188L 420-555mm (150 strut)

650GE288L 378-599mm (120 shock)
XS288L 375-600mm (150 shock)

Hate that word "droop"

Someone should blow up "droop" Can't we say "Postive frontal incline"

I cant agree more, its seems Prado point came up with this, have never heard droop before,in this context anyway!

Hey wheelan,

Suspension droop was not invented by PP!

Just google suspension droop.

"Droop" is easier than "suspension down travel", I guess. Unfortunately, droop also sounds like something you need to take drugs to remedy.

Maybe the word droop is just a touchy subject for some

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.

[Whitey Shockie Maker of the Month Award Find all posts View Profile Close Whitey]

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!

That's good to know 120D4D as I've put the deposit down for the order, so I'll update when received with actual measurements (late next week).. I'm hoping for c.+30mm against catalog/advertised measurements which would correlate to your above measurements for the 90000

Thanks Mark, it'll be interesting to see what the actual measurements are, or if someone else has already done this

For the OME front strut I get 440 closed and 570 open. Just measured one up, center of bottom eye to base of top pin.

Mick

As you can see by this old post from page 1, the discrepancy in ARBs measuring method has been there since at least 2011, unfortunately they don't seem to listen. Rest assured that the OME Sport 90000 has in fact been measured at 570mm open and 440mm closed length as per the measured data in the database.

[Whitey Shockie Maker of the Month Award Find all posts View Profile Close Whitey]

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!
