Hi guys was just wondering instead of buying the full highsteer kit will a 3" drop pitman arm do the same thing with my spring over need help asap so i can order it

[SierraDan]

It will help. Depends on your lift.

If you're trying to do SPOA on the cheap, you shouldn't do it.

[Azza zook]

Ive done the spring over already just need to fix the steer so you think go for a histeer kit?

[SierraDan]

Yes .

You will still get bump steer with a dropped pitman arm, and running it from under the spring to over the spring will cause hassles when it flexes...

I'm pretty sure the snake racing knuckle was originally built on a bent sierra housing, so it chews out inner axle seals very quickly, and the LROR high steer kit bolts to the king pins and brake bolts. If your not engineering it buy the LROR high steer stuff. If you do end up engineering it and using the snake racing knuckle, you will either need to rebuild the front end every 5000kms, or get it machined again...

I ran my secondhand snake racing knuckle for more then 5000kms and had no problems with leaking seals??

Siq .

[rustyzook]

there is a merc steering lnk that can be made fit, but prob no legal

[TWINCAM16]

i heard the toyota torago has a steeriing arm that has the same spline as the vitara power steering box but is droped and good for lift kits?

just hearsay tho

[rustyzook]

drop arm still wont eliminate the need for histter or poor mans killer link (Z link cringe!) it wil just allow the steering arm to sit lower and flatter

to fit the vit steering a wedge is needed correct me if im wrong ive never done it, ive heard jimny box bolts straight in, again never done it just something ive heard, fat zook or appsie or someone most likely can give you the info on this as i know appsie did the vit 1.6 on his black sierra but again i never have and dont know

the merc arm bolts onto the knuckle some where but must me bent out to fit i know there used to be a zook around here that ran it and was engineered but no idea if its still can be done, here is the build no idea if there is info has been years since i looked at it

Ok thanks guys i appreciate the help

Not answering the original question (certainly not with an orginal answer).

There is a real trend on Ausookers, the higher the post count the lower the sierra (with a few exceptions).
If your going SPOA then do it really reallly well, or stop now and go back before its too late.
Consider returning to SPUA rather than putting more into the SPOA and taking it out later anyway.
up to 35s will fit before going SPOA.. bigger than that on a SWB and you will want to stretch and coil it or at least bigger diffs.

I'll add to that neo - lots and lots of the more experienced members of the board used to have SPOA cars, or have built them, but moved away from SPOA because they struggled with the compromises.

I have no doubt that a safe, strong car can be built SPOA. Alien's is a good example. However, that was a massive amount of work. Dan's comments are spot on. If you want to do a cheap SPOA, you shouldn't be doing it.


Steve.

PS I can confirm the snake knuckle isn't machined correctly and kills axle seals, and the merc arms are hack. Steering the car directly off the calliper bracket doesn't even sound right, don't you think? That's even before you take into account elongating a hole to make it fit. Z links are also poo. Sierra's bump steer too much when standard, let alone with 5" of lift. Hi Steer is the only acceptable way of correction IMHO.

[dono1]

My SWB sierra was SPOA when I got it ( I wish it wasn't) I got a Lowrange highsteer kit because the Z - link is WAY too dodgy!
It's been 6 months and I am still fixing the previous owners shortcuts.Now I am waiting on custom driveshafts to be finished......

[Mitchie.1]

the rocky road kit looks like it maybe a bit better. it bolts to the king pin and the caliper mount.

[SierraDan]

Does it replace the knuckle cap like a hilux one? Or use longer bolts and sit on top?

[Mitchie.1]

Like a hilux one.

it replaces the king pin, its quite a good kit

[SierraDan]

That's cool.

[alien]

the suzistore kit i run in my sierra, although not cheap, picks up the caliper bolts as well as the factory arms (the machined spacer between stock arm and hi-steer arm is missing in this pic):


its 100% engineered in WA (made from a specified grade of steel, no welding etc etc.)

edit: Here's another pic:
