rear upper shock mount

[pawl]

I'm looking to replace my rear upper shock mount mainly to lower it and looking at the rear mount at full flex, I feel there is too much pressure put on the eye of the shock as I think the pin of the mount is at the wrong angle as it points up. A while ago I stumbled on a site but can't find it again that made a shock mount that rotated the eye of the shock 90 deg so at full flex there was no sideways pressure on the shock mount or eye. Has anyone seen or know of these mounts?

Why would you lower the mount?

To achieve more suspension droop!

But then you have to increase the bump stop height or you risk having the damper go metal to metal at full compression, so you gain nothing in terms of overall travel.
I know this is popular in the UK, but it's always puzzled me. IMO you'd be better using a longer travel shock and raising and re-engineering the mount to suit. (as long as the springs are an appropriate free length too )

LRA used to make a kicker (tapered shim) that went behind the OE mount to correct the angle of it, but don't know if it's still available.

Rovacraft have them I think. If you want to import them, Expedition Exchange & Scorpion Racing also do them.

I wouldn't have thought that they'd that hard to make from scratch though.

Paddocks do them too. Theirs is a plate that relocates the original whereas the ones from Rovacraft (Scorpion ones) are a complete new lowered unit.

I have them on mine and also have 24" shocks as well and yes you do need to install extended bump stops (I get mine soon) as well you may need to extend your brake lines (if you have lift).

I have these type which you can buy from Rovercraft in Victoria

As for the bump stops and extended brake lines you can get them from Paddock spares in the UK and get them posted here.

Yeah I've worked out I will only get 35mm of extra droop from lowering the mount 50mm and packing bump stop 15mm to stop the Bilsteins from being the bump stop. But at the moment the billys are going to pop they are pulled that hard when the axle drops and IMO the upward angle of the (standard)pin on the top mount is all wrong( I have seen those kickers which would help), it puts alot of pressure on the top eye. Unfortunately I don't have the funds to get new longer shocks as I spent it on the bilsteins after being told they will go with the 2" lift I got from the new dobinson springs. Me thinks I should've gone the cheaper Pro Comps, but I hadn't heard a lot about them.

I went the procomps because they had the length that I was after and also the billies were to expensive for me

It's some messed up engineering in my opinion and for the life of me I don't know why the poms do it either. The only value I can see is that it retains standard shocks, when really some longer shocks should be used and preferably the shock mounts raised, not lowered so that you ca make use of the full longer shock travel.

I am with you Simon

OK then, I've got my thinking cap on. My billies are 553mm extended and 346mm compressed with an effective travel of 207mm. If I go the long Pro Comps they are 672mm extended 405mm compressed with travel at 267mm. Now because the compressed length of the Pro comps is 59mm longer than the billies and standard shockies, I need to raise the shock mount 59mm to stop them overcompressing? correct?. Then 59mm from the effective downward travel of the Pro Comps is 267-59=208mm, which is virtually the same as the travel now on the billies with the standard mounts. Something here doesn't add up. I know that to work it out properly you would measure the bump stop clearance with the axles flexed up to gain max travel but it seems by going these longer shocks I'm not really gaining effective travel at all. Am I on the wrong track here?
And then because the extended length is longer I need to go longer brake lines, tieing in the springs or longer springs etc. But being 60mm longer after raising shock mount the rear wheel would be 60mm further down into that rut than the standard billies I suppose.

Hmmm, the maths isnt working. By adjusting the shock mount height you're just making the shocks compressed position the same where it mounts to the axle despite being a longer shock. The procomp shock has 60mm more travel than your Bilsteins, so you axles lowest position according to the shock will be 60mm lower. You're gaining 60mm worth of extra travel.
