Hey

I think I'm hooked on buying a set of composit leads!
I have been writing with Flex a form
http://www.flex-form.com/
And they charge 435$ for a pair. Have seen some other being interested and asked for a group buy price. All above 8 pairs can get the price down a bit. Just have to be within a reasonable timeframe.
But I also ask for help... I cant find my way round the wiki suspension part, so if anyone could supply all the info you need to fill out the form on their site for a '76 B210/120Y I would be thrilled ^^
Have gotten the basics but could need some help...

Im going to pair them with a set of Koni shocks or something in that area, so the whole thing is updated.

Best regards

We don't have that information in the wiki for Datsun 120Y

There was a main forum: 2013 group buy

Aaaarh I see.

Hmm... Dam..

The spring measurements are ALL THE SAME for ALL 120Y
A-dimension overall = 1165mm ?
B-dimension center pin = measure yours
C-dimension arch height = measure yours (may vary due to age)
D-dimension chord = measure yours
E-dimension bolt diameter front = M8, back = M8
F-dimension width = 50mm
Spring Rate: *
Axle Percent Rate: maybe 56 front/44 rear?
Car weight: 1974 120Y 1700 lbs (HB210 is substantially heavier, 1976-1978 is heavier)

Spring Rate (steel leafs)
* for smooth ride: 109 lbs/in
* for sporty ride: 130 lbs/in
* for racing: 150 lbs/in

Also ask Flex-a-Form if their leaf is compatible with the stock B210 Iso-clamp

* Desired change in ride height

I'd be very interested in a pair for my 1200 ute. Does anyone have the info on the stock springs for the 1200 ute?

The stock spring rates are published by Nissan - you can find them in our tech article: Spring Rates

I found I had to get my leaf springs completely flat straight with no arch to get the ride height I wanted for my datsun 1000s. You might be better off with sports options on the tension and going flat straight with a minimum curve that way it wont be bottoming out however can also use weld on suv chassis cavity pockets to increase clearance once lowered to avoid any bottoming out. You would be able to use adjustable dual acting Konis or similar coil-overs to adjust firmness further as the leaf spring being flatter will have more flex.

I used 1989 nissan navara front oil shock absorbers for the rear they are short and cheap improving the overall ride substantially with very predictable steering once the rear is hardened.

Thanks alot guys!
Was also looking around for the info on Ratsun, but got to the conclusion that I will measure them precisely when i get my hands on them once again *Dont have dem currently ad hand*

But love the help and support there is here on the forum, when i get the order done, I'll share what I wrote so it can get on the Wiki.

Got some good things from this thread, a guy and his wagon, http://community.ratsun.net/topic/401 ... et-handling-72-510-wagon/
Some good things in between, and a realy nice set of traction bars on page 2 !!!

But based on that and some other info from the B210 forum and old composit postes, as there is other that have bought them before me, The springrate should be bumped up a bit when it comes to composit, so I'll have them make it 150 lbs/in. Or would it be better going 130 lbs/in and a set of coilovers if they are too soft? If the leaf first is too firm there is nothing to do right? If they are too soft a rear coilover would stiffen it up to my desire? Just thoughts.

D, Good points you have there, they offer a low arch version, they said, would take that of have them make it 2" / 3" lower. then blocks would have to do from there, but ad worst it's +/- 1".

Ask Flex-A-Form to do the rate factoring. If you want stock-rate, ask Flex-A-Form to make the springs accordingly. I would not guess at what the new rate should be

Remember that the stock leafs are too stiff for a smooth ride with only the driver ... they are designed to carry a full load (about 400 kg of passengers and luggage)

Lowering blocks wont help. At 3" lowered the axle bump stops are already hitting the body
