I have just joined this forum..I haven't had my Sierra 1990 model for very long. It was fairly stock when I got it and I would like to make it just that little more capable. So far I have fitted new EFS shocks front and rear.
I am now about to purchase new springs and tyres with my choice being OMEsprings and Maxxis MA-751 tyres.

I believe there are 2 different levels of stiffness and I would like to know the advantages and disadvantages for both?

Is there any other things I need to do with the EFS/OME setup like shacles bump stops etc?

I plan to do a little travelling towing a small offroad teardrop van I intend to build. I am not a full blown off road person ...well not yet ...but would like to know I have a capable little suzi that would get me into those out of the way places.

The tyres I have chosen I believe give me a good allround road dirt sand mud etc ability. Your opinions would also be appreciated?

Thanks from Don

With the springs, the stiffer ones are really for if you will be carrying a heavy load in the car. Thats the only real consideration there.

As far as the Maxis 751s they're ok. I have them on my zook at the minute. They're nothing special but they do the job.

I bought maxxis b4 christmas. Very happy so far. Much better than the coopers in the wet. They were like driving on glass. Maxxis' were about the cheapest "name" brand..

hey mate are u gettin new starndard springs or are they 2" lift?? if lifted you will have to extend the bumstops to ensure u dont bottom out your shocks, also if its going to be lifted are the shocks extended?? if there not theres not much point lifting as the shocks will be fully extended when u've still got room in your springs to move.

There is a few good things in the DIY section like a cheap 2" lift...

The EFS shocks I got from a business that was clearing out stock so I got them for about 1/3 price. They are made for use with 2" lift springs.
The OME springs are 40mm lift so I believe they will match up nicely.
I have read a lot of posts with varying views about bumstops but none relating to EFS shocks. Is it right to assume that the bumstops nead to be extended for all lifts?

Thanks for the response
I spose the question I would ask is what is special relative to the price difference some tyres cost remembering I am sticking with standed tyre sizes within the confines of QLD law?

I used to use the maxxis 751 on all my work utes, they are a great road/gravel road tyre. they are quiet , grip well and really last.
they arent fantatsic offroad in mud and dirt buy I think they'd be great in sand. All up a great value tyre.

If your looking at more offroad and mud got the maxxis bighorn.this is whay I'm running on the utes now.

The coopers were ATR's. wear was good at 130,000 klms. The maxxis seem to have the chunkiest treat pattern for at's. they hum a lot more then coopers. Haven't done any slippery work with them yet. maybe go to Thompson dam area in a couple a weeks.

Not necassarily. You need to extend your bumpstops either if the shocks bottom out on up travel or the tyres rub up under the gaurds on up travel

i got the bighorns as well, been running them for about a month 1/2ish no problems so far. not overly noisy on the road and they are pretty good off road. i climbed a loose gravel hill easier in 2wd with the bigrhorns than 4wd with the stock tyres. lol they were shit tho.

Thanks for the response.... Would like to know how they perform? I wont be getting the tyres for a few weeks yet..gotta do the springs first.

I may start a new forum post about the tyres..I still have a few opinions I would like 2 hear and cant find them on other forums.

Thanks for that....I believe I have it worked out.----->

1. Fit the new springs
2. With Shock hanging lose from top mount, compress it and measure the shocks length (A).
3. Extend shock and fit to bottom attachment. Measure shocks length (B).
4. Making sure spring hasnt moved relative to the body throughout this procedure measure the Bumpstop gap. (C)
5. So the if B - A is greater than C all is ok.
6. If B -A is less than C then add a bit more than difference to Bumpstops.
7. I will only be fitting QLD legal tyres so that should cause no probs but tyre clearance in up movement also needs to be more than C.
8. After spring fitment and with Shock disconnected from spring and chassie supported allow spring to flex so that brake line can be inspected for length.

Correct me if I am wrong..
