Hey guys.

 

So I broke a OME nitro shock the other day down at Hollister.  Need some advice on whether it was over stretched or crushed.  

 

HD springs with 1" spacers front and rear, shock lowering kits front and rear, sway bars still connected.  No bump stop mods.

 

Shock broke but was still charged, spring got dislocated, spring got put back in, shock then popped, piston fell and fluid everywhere.  

 

So my question is did this happen because the bump stop was not adjusted, letting the shock get crushed?  Or did it flex too far and yank the shock too hard, thus breaking the top weld?  

 

Thoughts?  

 

Second question, what shocks next?  Thinking the adjustable TF ones Jethro spoke of in the recent RRC shock post by Dino.

 

Thanks! -Chris

Neither.  Looks like the flex tore the eye off the weld.  The eyes have limited flex in the left-right direction.  That's the reason we recommend pin-to-pin dampers, but this is like the oil debate .... everyone has their own opinions.

 

Damper lowering mounts will make this work as the shock is shorter.  Leaving the dampers high means you can have a longer shock, increasing travel and decreasing angle.  Ours are actually moved upwards.  That's how we achieve the flex seen here (and elsewhere on this forum). https://www.facebook.com/RoverWare/

 

[edit:  I think you have your retaining washer on the wrong way too, but not sure from the pic]

Graeme

Well hot damn, I had no idea.  Thanks Graeme.  I didn't realize that about the pin to pin or pin to eye problem.  Looks like I'll be sending you some money soon!  I thought I had solved my problem by installing the TF shock lowering mounts.  These did make the ride better, and smooth out driving over speed bumps.

 

So what shock would you recommend for this situation, once I have you'r shock mount? And what length? 

 

 

Thanks!

Are you going to be at Catahoula tomorrow?  This is a long conversation with no one answer.  Hard to condense to the written word.  If that were possible, I'd publish a book and make a fortune!

Seems like Graeme has you sorted. One he does know well by watching his trucks is how to set up flex!

Speaking of that...Rene was interested in getting more articulation from his D2...thoughts?

The cheapest way is to buy a D1 .... but I have other ways too!

Thanks Graeme, and awesome meeting you guys the other day over coffee.  

 

You have any idea where to source the specific OME shocks Gwyn Lewis sells here in the US?  There's a lot of part number discrepancies between the few UK sites that sell the long travel plus 5" pin/pin shocks... and what the ARB website says it has.  Contacting ARB now actually to get to the bottom of it.  Shouldn't be so difficult!

It is a little complex. Gwyn also modifies them with his own hardware. He's a great guy; and we do a lot if business with him.

I don't think I'd be using ARB as my reference point for a long-travel Rover.  They certainly aren't into the rock crawling world in any way shape or form.    If Graeme can't sort you out try talking to GBR or RTE.  Even Lucky8 would likely be a better resource than ARB.

Yeah, pretty sure OME is a subset of ARB.

 

Regardless, ARB/OME isn't exactly about max-travel suspensions.

My (Internet) research shows that OME sold out .... shame.

 

They are still one of the best dampers (or shock absorbers for the non-scientific) for Land Rovers.  Over-priced, but the valving is near perfect for everyday use.

Yeah Gwyn Lewis' site says he adds/supplies "bush isolation washers" I think... so I'll have to figure that out after I whack off the existing locating cups on the D1 lower shock mount.  I ended up ordering the OME dampers from 4wheelparts here in Oakland, and I'll confirm if the part number is correct once they arrive.  Here's some pics of the failure point on the NitroChargers I was running.  The point of failure seems to be just press fit and not welded, which is interesting.

 

I had to drive home from Panoche Hills area yesterday after the second damper broke in the same fashion, and it was a terrifying and slow two hour trip, with the back of the truck bouncing wildly out of control at the slightest bump in the road, and with the steering freaking out as well.  Almost considered having it towed but I persevered and hobbled home.  

 

Do not drive a truck with no rear shocks/dampers.  You will likely perish.

 

Side note, the vehicle speed sensor (VSS) also shat the bed on the same trip, while heading up the Altamont Pass.  The truck's motor behaving like a governor was being turned on repeatedly, with timed intervals of loss of power... it was horrible.  It was occurring every few seconds for almost a full minute, almost underivable.  Unplugged it.  Drove the rest of the way to Panoche with not problem, and no speedo.

 

When it rains it pours.

Gwyn Lewis also sells on his eBay website too if it's something Graeme isn't able to help with.
