can some one list step by step instructions to re set my leafsprings on a datsun 1200 ute.

list and number the steps by some1 that has done this succesfully before

i want to do this and would like to see the instructions and it would also be good for others in the future to read befor they attempt to do this

thanks

Are you after instructions on how to re-arrange your leaf pack to make the car lower, or do you want to know how to properly reset leaf springs?

re-aranging is easy. Just unbolt, re-arange and bolt back together. Play around with combos to see what suits you best.

Resetting requires a huge oven like at susp shops to heat the metal up, move it then cool it... or something like that.

Resetting springs involves heating the springs to remove the 'spring' in the steel, then reshaping them to the new setting, followed by another heat treating to restore the 'spring' again.

There have been innumerable attempts at re-arreanging the spring stack, reversing one leaf etc. etc.
While this may affect the static ride height, it also alters the spring rate, often for the worse & also leaves the main spring leaf unsupported in some cases which means that the car is both unsafe & illegal.

If an unsupported, or inadequately supported main leaf breaks between the front anchor point & the axle the car can easily end up being 'rear steered' when that side moves backward, jamming the tyre against the wheel arch.
If this happens at speed, you're going to need a lot of toilet paper & possibly an ambulance.

The main leaf may not break only when going over a nasty bump either as it can develop a crack at the highest stress point. which slowly propogates & fails at any time without warning.

Resetting the rear leaf springs is really the only way to do it properly as the spring works should also stiffen up the spring rate while their at it to compensate for reduced suspension travel.

I just found an engineering shop that did this sort of thing.

They re-set mine flat/straight with no load and also added another long leaf to increase the rate (just slightly shorter than the main leaf with care that it can't foul the eyes at any time).

Has worked well in my coupe racer since the mid 90s.

Quote:And therein lies the secret of success. Do it right & you only need to do it once.

i was hoping to get an answer today as i wanted to do it over weekend

got a price for nearly $400 to reset from a truck shop

by the sounds of it no1 can do it on here

is it just as good to flip em over???

do i just
take leafs out

flip over

take the supports off that rap arond leafs

put the original bottom piece which is now on top on bottom

re clamp the supports

put back in

is there anything more to it that i havent added

i might just flip them till i get another set to attempt resetting cause by the sounds of it on here may be hard as there is smart people on here with the dato stuff and no1 sounds confident enough so may just wait till i get a spare pair to practice on

for now can some1 confirm in steps the flipping process

also ive seen alot of people over the years flipping leafs with no problems at all
i think its more legal then lowering blocks as police look for blocks in my area on the busy cruising days when they have a lovely day booking and defecting
i had blocks but sold them and need it lowered asap its like a 4x4 at the moment

cheers

The place i use charge $110 for springs to be reset and $180 for a reset and extra leaf added. $400 sounds like a rip off

if i can get done for that price between
sydney and southcoast
ill will do that instead
so if any1 has a buisness name and number for the price freak said post it

and can any1 list or confirm the steps flipping the leafs

cheers

Most common method to reset is cold roll or hammer press.
The companies that do it hot, Claim that cold resetting will result in sagging leaves. But they still advise that their hot resets need to be maintained and reset. Go figure
Let your fingers do the walking
