Suspension Database

[Peterpilot]

I spoke to Dobinsons earlier this week to confirm the data in the database is correct. The only correction to be made as a result of a change in specification was the free length of the C59-325 rear spring. This is now a free length of 420mm instead of 405mm, all other Dobinsons data including stated rates are correct. I also have some new data to add for KDSS equipped vehicles

If you or anyone else has any actual data from Dobinsons or any other manufacturer's updated specifications that is more accurate than what is in the database, please post it or PM me and I will update the database accordingly

On the dobbos, perhaps it changed when a lot of their specs changed 12-18 months ago.
New computer/engineering said no. A few things changed.

I'm 80% sure a standard 150 full extension is 540mm same as 120's not 555mm.

Also the rear Dobinsons, 329 are correct. 327 I think are 270pound. 325 are around 220-225pound.

I'm not checking it all, just observations while browsing. It's all based on my memory.
Definitely a good reference point.

I don't have a 150 front strut to measure myself and have to rely on other people's measurements. If you get to measure one yourself, or a workshop to do it properly let me know and I'll update the database

The Dobinsons data is probably the most accurate on the database. It is direct from Dobinsons in N/mm, converted to lb/in and verified by Dobinsons. Any variation is as a result of the conversion. To convert N/mm to lb/in I used this converter: http://www.hraefn.net/projects/spring_rates.php

Weird, we have always known them to be 540mm. I also measured 4 from 2 different 120's they are still 540mm From the base of the top pin to the centre of the bottom hole. I rang a mate, he measured his in his workshop without me saying anything he came back with 540mm. So you either measure differently or something is wrong with those struts??

I did measure differently, the lazy way by making a rough measurement on an assembled strut because I couldn't be bothered dismantling them

I actually dismantled one of my old TEMS struts today and re-measured them accurately on the bench and found that you are 100% correct. The extended length is indeed 540mm. I also measured the compressed length to be 420mm. Unless I get different information, for simplicity I will assume that the non TEMS strut is the same length and have now updated the database accordingly. Thanks for your input, ####

Interesting, the OME 894 is also mentioned in an FJ forum, but with no specs: http://www.fjcruiserforums.com/forum...ion-guide.html

OME never mentioned them to me when I made my enquiries and given the age of the posts, it is possible they may be discontinued.

The 894's were mentioned here
http://www.pradopoint.com/showthread...ings-or-shocks
http://www.pradopoint.com/showthread...s-and-decision

The first link was the reason I came looking for it here in the database.

The specs for OME 894 are decidedly absent....??

I'm not aware of an OME 894 rear spring, I guess that would be a standard height spring. There are quite a few rear springs missing from the database, my research there was not exhaustive. To be honest, rear spring data isn't high on the priority list if you drive a Grande

If anyone has information on the OME 894 or any other spring or shock not already in the database please...

Feel free to post any additional manufacturer supplied suspension data and I will add it to the codes.

The text you have quoted is talking about front struts, they are completely differnt on the 80 series compared to the 120, so front 80 series shocks wont fit.

As for the the EFS rear shocks, you will need to check the body diamiter of the shock, I recall some of the 80 series big bore shocks wont fit due to phyical diameter. As for them giving you maximum flex, thats hard to answer. Yes extended sway bar links will help flex in most cases, but you will need to find the open and closed specs of the shocks you are looking at. Whether they suit will depend on what springs you have fitted and the amount of lift you have, no good having heaps of flex if the spring is too short and falls out. Likewise if they dont close enough you will bottom out the shock and wreck it if you don't extend bumpstops.

I know that doesn't answer your question, you might just need to get the shock specs and get the tape measure out and see how much flex you can acheive with shocks and sway bar removed, do the maths and compare that to the shock in question. Thats how I settled on the OME N71E 80 series shocks I run, they had the optimum open and closed measurements for my suspension set up.

Hey guys,

do all 80 sereis shocks fir the 120 prado? I have access to cheap EFS shocks. I am keen to get trhe most flex out of the rear. will extended sway bar link pins, and 80 series STD length shocks provide this? Just as OME nitro sport would?

Cheers and appreciate all help!

I've also just re-measured my old OE front struts and found them to be 545mm extended. They gave me a total downward suspension travel of 845mm when they were fitted. According to Lovells, my current front strut is 570mm extended and when measured gives me a total downward suspension travel of 895mm. As I would expect, a 25mm longer strut results in 50mm more downward suspension travel. This confirms to me that the OE strut is in fact 545mm extended
