Nah not the shock bottoming out but hitting on the bump stops. That is the 3" lift flexy coils and 820mm shocks, more flex then a 7" lift Patrol. I will add that they were happy enough not to change shocks over but I won't be recommending this.

That length shock, and coil, it aint hitting the bump stop, thats for sure.

Shock mounts arent designed to be bump stops, so it "may" damage the shock, it "may" damage the chassis.

True

Actually the rear upper shock mounts on some later model GU Patrols are prone to cracking and breaking off. The welding hasn't been done properly.

4WD Stuff wrote:Our Boss adjustable 820mm shock has 12.83 inches of travel and most people are quite content in fact stoked about this much travel. If you plan to run longer shocks you are quite keen for max flex.

In a month or 2 we will have 782mm or 12 inch travel shocks available for the 3 inch flexy coils. We have found that if you run longer shocks without changing the mounts you sometimes hit on compression on a bumpy track so you lose some of your ride comfort which the Boss shocks have plenty of. You will find you won't be on setting 1 or 12 but somewhere in between.

For the 4" lift we have to do some more testing on a bumpy track with the 820mm shocks before I can be really sure. If someone was thinking of testing them on a 4" flexy kit, I am willing to swap them for the slightly shorter shocks if it is a bit bumpy.

Shane
what size Boss Shocks would you recommend for a 7" lift, i know u don't like them but hay, some of us do have large lifts, i want max travel out of this damn thing. especially the rear

getting the front working nice just need flexy 7" coils now

We do have 7" flexy coils which are the 6" heavy duty flexy coils so they won't suit every application. At this stage you get the same flex out of the 5" flexy coils as we do out of the 7" flexy coils so you are looking at 820mm extended length shock. (Some customers say that there is no need for drop out cones but it is borderline.

If you want to run drop out cones or tie them in then you are looking at 900mm as an option but I haven't tried the 900mm shocks with the 7" lift Flexy Coils so I would guarantee that if they were too long for the lift we would swap over to the shorter shocks.

Yep the Nissan is not as bullet proof as we would like. I won't compare it to my Jeep though.

Shane, i'm thinking of getting some boss shocks of you soon, but i'm a bit concerned about your return policy.
You say that if the shocks don't match the lift you will exchange them for a suitable length which sounds great, but is there any chance that if i order shocks of you that they would of already been in someone else's car?

It is a bit funny that someone is worried about me taking stuff back too easily but still a good question.

It is very rare with shocks that someone returns them. With coils that are returned it is usually within the first day or 2 because I sent the wrong coils. I have a corner I put them in until we have time to sort them out. Then if we run out of stock and someone needs a particular coil I check out these springs and offer them at a reduced price and the customer knows before hand and makes the decision.

They are foam cell. They are made in Taiwan but not selling them now because of way too many warranties

We dont, as we are a specialised shop, and as such arent a "generic wholesaler" we only sell what we think is the the best product for the job, not what we have access to or the best margin on.

We do have a web page being constructed at the moment which will allow our kits and parts to be purchased and Q and A that are common, but thats still a month or so away.


Just a note on foam cell, if you do touring, instead of weekend warrior stuff, if you get a foam cell hot, the foam breaks down, the shock gets foam in the valve, and it stops working, goes stiff as, and wont recover like a gas/oil shock.

Just an FYI.

tailpipes wrote:Done heaps of searches for this cannot find anything. Wounding what length shock to run front & rear? Using 4" flexy coils super flex arm & long arm kit with no body lift. I would love to be able to use these arm to there full poetical so if anyone is using this same set up i would like to hear what you have done thanks.
hey mate, only just found this post!
I probably can't help too much with shock info as such, but i can say, FRONT - superflex arms will be able to use up to 12-14" of shock travel.
REAR - long arm setup can easily use up 18-20" of shock travel before bind.

So from initial testing, the longest off the shelf front shocks were 10" travel, but BOSS have some sweet 12's, which work great due to the 'modular' mounting setup, so you dont waste too much compressed length. and on the rear, if you are really ingenious you might work out a way to fit some of the BOSS 1m (17.2" travel) that would be insane!!!!

this is with 18" rear shocks

hope that helps

Edit: I was talking about how expensive Fox shocks are. I now believe it is worth spending the extra dollars to get Fox shocks though they do cost a fair bit.

4WD Stuff wrote:I have been told that Fox shocks are great for racing, they do the job well but they have not been designed for long term use without being rebuilt. Therefore they won't last as long as even some of the cheap brands for touring purposes unless you are willing to get your hands dirty to rebuild them.

The questions you always have to ask is what is best for the customer which isn't always going to be the most expensive item.

Shane
Quality parts, are quality parts, some of the 4 and 5 yr old Fox stuff out there on touring wagons up to and over 4 tonnes loaded, doing all the big trips havent required a rebuild as yet, so dont always believe what you hear, no matter how much it helps your story ;)

Mostly they are pulled down for revalving, in specific applications, for different tracks, by the offroad guys who race on them.

Incorrect fitting, like not the right bump stop length is what does the damage on shocks, and was an issue for tough dog, when they sold "6" lift kits" with longer shocks, and half the installers couldnt figure out what to check before sending the car out, compress the shock, damage it, no workies no more.....

I have helped plenty with foam cells that have stopped working doing those bigger trips though. [and why does every broken coil I see on these trips seem to be a Lovells ?] Hence the warning, its not good on the rest of the car when a set of shocks wont compress.

As for cost, thats why we went Ridepro for the budget concious, the build quality of a Koni for half the price, with the lengths and valving required, double welded eyes, extra durable bushes, better RFA by 50% on the shafts, to help the seals last, all good stuff for the customer, without being expensive.

Always the best part that suits the job description, not the "best part" period. ;)

I changed the color on the good ones, so they werent "white" to be confused with most generic whit shocks.

Shane
We didnt try and stop supply of the old design slinkys that didnt work, and sagged over time, which are the ones they are selling to others, only the ones that worked, but they were supplying those to anyone else anyway.

Didnt realise you felt a need to defend your product, or at least not until that last post.

Did the "expert" installer by any chance check bump stop lengths, and extended compressed lengths ?

Or did they just prove my point ;)

I am certain Ridepro shocks do just fine (I know who manufactures them) however they are about the same price as Boss adjustable shocks which makes it a no contest in my opinion.

Shane
As you said, depends on the use for the customer, anyone in a heavy truck going touring, shouldnt be using foam cell for reliability, thats why I mentioned it.

A shock that has every part as a spare part, and easy to rebuild, if required, spend some more, own them for life really, or chnage the valving at home in 1 hr, thats value ;)

As for who mkaes the Ridepro's, didnt know it was a secret, but like anything, you go there with a spec, they make what you ask for, the better components and spec you give them, the better product you get.

Just a note to all. We in the north sell 1200 foam cell units a year, yes some are used almost exclusively as touring wagons but many travel vast distances on some of the worst roads this country has to offer. Although we do see a minimal number of failures with the foam cell we have NEVER, repeat, NEVER, seen the foam break down, due to heat, abuse, over extension, lack of bump stop or small green aliens invading the interior of the shock. So we have never seen a blocked valve or shim plate, or a locked shock. I have seen foam cell shocks fitted to professional tourist landcruisers that have had the paint blister on them and (once cooled) work again. once again selling the customer the right product for his/her application is crucial, but as for foam cells being out-preformed by a comparatively priced gas shock, not in my experienced. Would love to see evidence (photo?)of the melted foam material, or the failed shock or both. P.S. We also sell gas shocks and find a greater failure rate in % to numbers sold. in 4wd applications.

We must just either help those who do, or get them here spending good money 2nd time around on what they need ;)

Foam cells are a cheap manufacturing process, and work well for steering dampers where they need to run horizontal, old technonlogy really, bit like running timber spoke wheels, when we now have alloy or steel.

Wooden Wheels! How many wheel manufacturers still make wooden wheels? Yet many shock manufacturers are moving to foam cell tech. Do you think that these manufacturers know less than you, is the substantual dollars spent in there R&D departments ignoring advancements in gas/oil technology. I think not. I repeat my first statement, if there is falure you have witnessed, show us, the masses, the proof. Large capacity remote canister gas shocks will continue to rule the comp world, but for many of us that need a reilable, effective, multi use shock foam cell is a viable and effective solution. Foam cell was first used in steering dampers so that a store of oil could be retained at the footvalve in very low opperational angles, so why doesnt the same apply in an acute angle shock mounting? In my experience (22yrs) i am yet to see a foam cell shock fail due to melted material. 1200 units per year. 1000's of km of dirt roads at my door step, cruisers, patrols , navaras, hiluxs, jeeps, all of them. no melted mateial. all on foam cell, none on wooden wheels.

I bought a lot of a suspension off Shane for my shorty maverick, (4.5 inch springs, boss shocks, superior drop arms, panhard rods ect) He was really helpful, after i fitted the new gear i found the rear flexy coils (which i did ask for) to be way to soft (which Shane did warn me off, I thought she'll be right mate.) After testing it out I rang Shane and said WOOO MANN! too soft in the back! Its scary! He said no worries mate, I'll send ya something more suitable (at no cost to me) I fitted the new springs and haven't looked back. rides great works great off road (still miles of flex) and doesn't rear up nastily as shorties tend to do. I think the flexy coils wouldn't be scary in a LWB, they deliver what they promise, they definately do flex! Also while I'm going the boss shockes work great, heaps of extension and compression and they really are adjustable, amazing how much different it makes in the ride by turning the adjustment knob.

cheers Tom

None that make quality.

But foam cell is the equivilent of wooden wheels...

High pressure gas seperated by piston still is the top choice for the best tunable performance from a shock absorber, to suit varying loads.

the lonfg and the short of it is, barely anyone is gonna pay top dollar for fox, king or any other high end competion style shock when a set of tuff dog, boss or whatever foam cell are gonna do a good job, probly even a great job, maybee not the best job but still good enough for the outlay. The suspension assasin sells is way outta my price bracket and i am doin pretty good at the moment (110k PA), so its reasonable to assume that if you do have 10 or 15k to through at some shocks and springs then fox or whatever may be the way to go, but for the rest of us the cost just cant be justified.
