Need opinions of which bolt on rear shock mount to get.
Cheers Mitch

firstly why do u need one of these? if ur after more travel it wont give it to u,for starters if ur shocks are angle in u will have a crap ride and it will handle like shit, if u have a spoa its still n ot required, if u have ur suspension set up right its not required.

X2 i jst used some flat bar that bolted to original mounts and had some new captive studs about 3 inches in on each side!!! took about a hour or so!

i made my own out of 40mm box with sections cut out to fit the longer shocks. i used triton rears. long enough and nice and soft.

Bluemax also make a long travel shock for the zuk which is REALLLLY long. theyre going great in mine.

by get it up there
I have some good pics of how i have done mine.. i only did it a few weeks ago.. but i cant figuire out how to put them on here sorry!!! I'm running rancho 9000, and the top mounts are 6" apart.. works well

if fitting LONGER travel shocks what are our options.
i DONT want to cut into my floor for shock mounts!

have a look at the pic and at ur own vehicle and tell me how much of that travel u actually use when ur shocks are in such an angle, u might get a bit of a shock. ive had spring ova zooks and an overkill coiled zook and neva had to do this and still had enough travel left not to stuff up the shocks, do ur homework and take sum measurements do sum simple mods and u might be pleasantly suprised.

I don't think these are really necessary either, I've seen plenty of zooks with huge travel and big lift without them. Shit my 5" lift doesn't require them FFS and I have bucket loads of shock travel left. I can't see SPOA being much worse. It's just a matter of picking the right shock, and there certainly isn't a shortage of choice or info on the subject. Fitting cheaper shocks is the only benifit I can see of this setup on anything but rediculously modded comp vehicles (in which case better suspension designs are available)

X eleventy. Laying the shocks over at such an exaggerated angle heavily reduces their effectiveness, by reducing the effective shaft speed, messing with the velocity sensitive valving.
It's pretty funny really - a stock sierra shock is 6" travel. In the angle they're mounted in a stock sierra, they're probably able to provide about 7" of actual wheel movement.
A stock sierra shock laid over at 45Ëš would allow 8.4" of wheel travel - way beyond what stock rear springs can allow.
laying over a 10" shock at (say) 45Ëš provides 14" of wheel movement... more than any leaf sierra could hope to produce.
"Inverting" rear shocks is really only a way of running "generic" shocks and allowing for large spring lifts.
Even with the setup I build using N76 shocks, there's about 4" of wasted shaft travel with an OME sierra rear spring and longer shackles, and that's with the shocks through the floor and trying to mount them as vertical as possible.
Anyway, if you have all the other work done to use shocks this long, you are way beyond a bolt in rear shock mount.

i found the limiting factor in the rear suspension in my sierra was the shocks and the CHEAPEST solution was to move the top mounts inwards. im not worried about how it handles as it only gets driven on a weekend when i have time. If it was a daily driver then maybe i would do something else.
And the question that was asked was
Need opinions of which bolt on rear shock mount to get.
not what do you think i shouldnt do.
bring it on!!! Flame suit ready

I'll be putting mine on an angle in the next couple of weeks because its the cheapest and easiest option for me. I've been driving a few km's latley with no shocks in the rear at all and i reckon angle mounted shocks would have to be a slight handleing improvement?

i do understand the valving issues experienced with putting shocks on an angle but i have long ranchoes that i want to use and dont want to cut holes in the floor to stick shocks thru!!! what are my other options??
the only real thing i can think of is doing a swap with someone else for shockies!
what are these n76 ones your talking about steve? got any pics of the 'thru the floor setup'??

Basically as Gwagensteve has has about laying over your shocks is that when your Shocks are inverted 45Ëš When you say your wheel or axle travels up over a bump the say it moves only 1inch up your shock its only moving roughly 1/2 a inch its roughly only doing half its job it could be.
Im running inverted Rancho Rs5000s they work well in the slow stuff but on the road it roles around like a boat, I put up with it though. I now have RSX91119's for the rear so Im going to try running a harder setting to get a better ride out of the rear on the road. As for the front I have longer shock towers and the shocks mount to the diff. If you just invert the rear and dont match up the front your going to have a 4by that doesn't flex equally which can make it become unstable at times or in certain situations.

thankx mud but i dont think u understood. i have the same setup as just cruizin with my longer ranchos at 45 degress, i AM experiencing bad handling especially with a load, (VERY BAD) and was very interested to find a way to fix, make them more vertical, the problem WITHOUT cutting into my floor or REPLACING my ranchos. but i can replace if i can get a better ride but would rather not as i have them and it would COST money to change

Yes but if I were the person asking I would appreciate being told that's it's not the best idea and given the justification why. That's why I consult these forums, to gain the collective knowledge of experienced members. I'd rather be told now then find out down the track after I've spent the money. I just wish people would do a little more research and for once actually use the search button
End rant.

cus the search button sucks. theres more shit than good. me personally work from pics and in the majority of the results are from 2005 and the pics have been deleted.

Yes you loose the dampening effect by inboarding the shocks but don't forget the shocks most ppl end up running aren't designed for the light weight Sierras, most are for vehicles almost twice the weight therefore the valving is drastically different.
To fit long travel shockies anything longer then standard are you going to limit up travel? Mostly yes because to get get drop even for 2" springs the shockies will limit compression. As you can see from my previous pic I touch the bumpstops and this is with 4 wheels still on the ground.

Gotta love that flex. How is the cert coming along? Is it just a case of finding a "round to-it" still?

take ur shocks out ramp it and measure it, its the only way ur goin to no what length shock to fit, ur obviously not spring ova and only runnin a 2" spring lift according to ur sig, do sum home work take a tape measure with u and start measuring shocks that will fit, like has been mentioned earlier there is no need for all this layover crap.

im spoa at rear only.
front is sorted
bazooked- have u got any pics of your rear setup

N76 is the model number of a very long, very soft OME shock, designed for old school VW suspension based off road race buggies. It has about 10.75 inches of travel, plenty for pretty much any application except compensating for something and boasting on internet forums.
From top to bottom, here's the lengths of some shocks for comparison.
Stock sierra front
Stock sierra rear
RS9026 (can't remember, we wanted a 9010 but that wasn't available)
N76
OME 80 series rear.
In any case, the N76 isabout 4" longer than a sierra needs, even with RUF in the front, but it's valving is beautifully soft, is easy to get, and has a good performance/price ratio.
These are the only photos I've got really.
The body wasn't sitting down on the chassis in these shots. The mount sits about 3/4" though the floor with a 2" BL and 2" bumpstop spacers. with neither, the mount would be 4" through the floor. obviously with a spoa, you'll have to work mount height out based on bumpstop location.
Laying shocks over is really very hit and miss for length and valving.

I too agree there is no need to be laying shocks over if your still using sierra leaf packs...you just don't need them. I have done the measurements both with my current setup and how I used to run (2" spring, 2" shackle and 2" body) and the travel just isn't there to require a longer shock. I think some people are getting a bit confused when chosing their shocks. You may be using a certain amount of travel on droop but then hardly compressing the shock at all under up travel. The best way is remove all the shocks, flex it up, measure front and rear and consult a shock guide to chose the most appropriate length and valving to suit your needs. I got procomps front and rear and they are spot on the right length and offer a very balanced and quite comfy ride.

when u do your initial compression and extention measurments on the rear, are you going from std mounting points?? if not where from?
