Hi there, can anyone advise on using additives on deisel engines. I`ve
heard that since the petrol companys cleaned up the quality of the deisel
fuel it may not lubricate upper cylinders as much as before?
Also front leaf springs saggy would like to replace with +50mm lift, leaf springs to get it out of the mud a bit more, also same at the back, will I
need to get it certified. Vehicle is a Hilux and has a cert for 15x8s and bull bars.
1st 4x4,1st deisel,1st car worth more than 2 grand.
Any help welcomed.

Cheaper options are longer shackles - easy to make yourself - but shouldn't be more than 50mm longer than standard to keep it legal - then again, unless the WOF guys know what the standard length is, they won't know if it's oversize. The downside of that is you only lift the truck half the exta shackle length cos the axle is half-way along, also the shackle hangs lower. Works OK on the back, but on the front it tends to find the ground a bit too often, also changes the steering geometry a little. I've had my springs (FJ40) reset at the local blacksmith for $160 per pair. Included replacing an old leaf to give it a bit more life. I lifted 3 inches (but they had probably sagged about 2in), and it seems to have worked pretty well. I'm told it will sink a little, & should soften a little over time, but that will happen with new lift springs too. Heaps cheaper than get new ones though!
You can to a spring lift of the 50mm above standard without needing certification. Not 50mm increase in shackle length. Changing shackles will require certification because its a do it yourself job and can be easily done wrong. This is why all the suspension companies do a 50mm spring lift becasue it does not require certification. You can also do a 50mm body lift without certification. Not sure if you can do both body and spring lift though. You will have to check with your low volume vehicle certifier on that one.
Go for the new springs and you wont have any issues with WOF man. Unless you get a real nasty one. And they do exist. And then its your job to prove them wrong. Good fun. If you use a tough dog or old man emu manufactured spring you'll be fine. Talk to the spring dealers about it too.

Hey fella`s, thanks for all the advise, hopefully I`ll be able to get enough
money together to go down the new spring option, as I would like to do
greasable shackles too. Also I don`t think I`ll get away with doing the shackels as the WOF man took quite an interest in the suspension at the last WOF, and that is still standard.
No doubt you`ll all hear from me again as I`m a bit of a green horn at 4wdriving. Thanks again.

Hey Wopass - thanks for the plug, those are my auctions... just trying to drum up a little interest in the new MaxiTrac stuff...
Jaffa - the cost of new rear springs now is almost the same as new ones and probably just not worth it to do as they do sag quite quickly in many cases. And the Hilux front is a spring-killer due to the torque rod setup so resetting them is normally a total waste of time.
Hilux front springs are $265 per pair, and rears are $350 - these are 50mm lifted ones. fitting is $100 per end, or $150 to do both ends.
Mumad, the rubber bushes slog out faster, but do allow more movement. The urethane ones have a better life expectancy tho. Personal choice really...
