Default Super smooth suspension

What's needed to get a patrol suspension so it super smooth? Coil rates? Or just expensive shocks?

The smoothest 4x4 suspension I have ever experienced was LC 100 series with solid axels, off road we hit some small washouts at speed and I braced thinking we hit that with way to much speed. But when we hit the wash out it was so smooth it was honestly like the washout had disappeared .This rig was set up well but his suspension was nothing fancy, his shocks were the arb ltrs with the remote canisters.

What setup makes your patrol super smooth?

on a budget; genuine bushes in good condition, new tie rod ends, correct geometry, old man emu coils and shocks, tough dog sv5000 damper.

no budget; king coilovers, king hydraulic bumpstops, new genuine bushes, superflex front arms, drop boxes, rear A frame, and rear longarms, tough dog front panhard, king damper, allans steering arms.

My 2c - adjustable shocks. They allow you to compesate for load and conditions, so you set them how you like.

The smoothest patrol I've been in was a heavy gu ute with 4 inch coils dropboxes and pro comp shocks, it was such a soft ride, off course vehicle control was non existent and body roll was interesting but it definitely rode nice. Also 15 inch rims I think the extra sidewall of the tyres helps a little bit maybe.

Interesting subject this one, and dependent on the person assessing the level of comfort. For the pothole condition you used as an example which is only one of many suspension conditions depicting comfort level but for that particular condition spring rate and damper level and to a lesser degree suspension design controls how the car will feel. For our patrol, correctly set up hydralic bump stops can go a long way to help control the level of comfort for this condition. The trouble is for all this suspension design stuff its one big compromise, if you change one bit it effect another suspension effect. Say for this example if you change spring rates and damper valving to suit a pothole condition then the car would float on corrugations or roll on a turn that would be unacceptable and dip severely under braking on and on etc etc.. As a general rule progressive rate springs or air bags with correct dampering seem to be able to produce the ideal compromise for comfort level in these conditions.

or in this particular case it might be just a toyota thing. in all cruisers, (except the whole 70 something range) what amazed me most was how much more comfortable and smooth the ride is. they sh#t all over patrols in this department. compared mk to 60series, GQ to 80, GU to 100.

You would be right but as stated above design to a lesser degree. I don't think there is much difference when both are in standard height and trim, Range Rover is better again but for our Nissan it seem the higher you lift the car the worst it feels for just about every component of comfort..drop boxes do help but for some reason not as much as you would expect. I think it has a lot to do with the length, position and angle of the radius arm.

Smoothness depends firstly and mainly on your suspension geometry.
Front arms and rear upper and lower arms with mount points in line horizontally give the smoothest ride but it's a compromise with lifted rigs.
Spring rates to suit your weight plays an important part but the type of shocks used and their long term durability will have a major impact and this is the area where the main improvements can be made when geometry is compromised with lifts etc.
The best ride I've experienced in a coil Patrol so far (4" lift and drop arms) had Fox 2 shocks. Didn't even feel those pesky speed humps at any speed. The wheels went up and down so smoothly without the body moving up or down at all like it stayed level.

Well it sound like I have everything right other than decent shocks. Mine seem to be leaking from the adjusters so they will need replacing soon

I have heard the kings are great quality and don't seem to get leaks. But I also heard their open and closed lengths aren't well suited for patrols.
Can you buy them here as bolt on kit with the right pressures?
What's the pricing like?
They look easier to fit due the hose for the remote canister being closer to the base. The shocks with the canister hoses coming of the top need the front shock towers removed to get the canister out.

Yes, phone Allan at racebred4wd . . . . 0351 341 007

he is an official king distributor, and knows all about them and patrols. he did weemans, and mine. . . . supplies brackets, mounts, and bolt-in kits to patrols for their bumpstops/dampers/shocks/coilovers etc and can easily organize shocks specific for your car. does nitrogen charging, rebuilding, custom valving, and shims. . . . .

Large diameter tyres too.
If you hit a 1 foot diameter pothole on 37s its way smoother than on 31s.
Low spring rates, correct shock tuning, not too much lift without geometry correction.

Another issue is your arse is placed over the rear axle in a shorty.

No such thing as a nice ride back there.

My GQ has all fairly new genuine bushes, 4" suspension stuff flexxy coils and bilstein 5165s rr. I'm super happy with this set-up after having OME, EFS, Dobinson, and Procomp. When setting up the GQ my aim was to make it as smooth as an 80series. I have two toyota mates one with a 100series and one with an 80series(OME 2"). They both have commented on how smooth the ol GQ is down rutted tracks.

My next step is swapping the drop arms for drop boxes. Mine does jarr throught the chassis a bit.

Kings are definately the way to go. King does a replacement oem shock for patrols. Get onto this mob, you wont find ANYONE that sells kings cheaper.

Wow and thanks for the link great prices!

Is it worth the extra $80 for the adjuster? And where can you get the recharged around Brisbane?
Can you use the pigback mounts on the rear shocks?

Click on the king shocks and scroll down to the 2. performance series smooth body, there 3 cheap options and heaps more expensive options if your racing.

sim,
if you are keen and able to come up brisbane northside one day for a test run, i have a setup you will love! and for a great price. I have been playing with shim setups and i think you will be amazed on how well we have got them to ride. I may be able put you in a few rigs with different brands to try, we have rigs with kings, fox, profender and amada.

pm me if you want more info.
Greg
