Thread: Superior Engineering Superflex arms for Rovers.

Nothing. My phone conversation was something like,
Me- i want some superflex arms for my rangie and looking at some amada shocks, these are the lengths i am looking at ######### and valving to suit as i am running an isuzu engine.
Them- yeah no worries, we'll look into what valving you need and we have legths to suit, whats your name and number, will call you back in a few hours.

Guess what, nothing!

Called again a few days later to jog their memory, said they will check up on it.

Guess what, nothing!

Lost my business

I can tell you my vehicle is absolutely more capable in the last four years with longer travel shocks, then prior when it had 10 or 11" travel shocks.



My current shocks are approx 880mm extended and 515mm compressed measured from centre of eye to centre of pin mount (not base). Custom upper mounts were required to fit them.

The up travel is only about 5 inches in the front and 4 inches in the rear, the rest is all droop.

yes still in the back of my mind but so far I have not seen any difference in reality, so far I have driven everything other members of the groups with much longer travel shocks have driven.

Given that your D2 is locked in the rear with an ATB up front and traction control, I'd have thought your theory was incorrect by me driving up Spanish steps just after you with similar, if not less difficulty, in my open diffed, but flexy Range Rover... of course one could blame the wheelbase of our cars, as the longer vehicles seemed to be better suited to the steps. But it was a case of lockers vs. balanced flex...

A well balanced suspension goes a long way to making a car capable if one is capable of driving it to suit the set-up. That is why there's a set of 12" 7100's sitting on my shelves waiting to get swapped into my mall crawling, daily - D2

That same reason is why there are long travel shocks sitting there to be installed, not diff locks! I simply have no need for them in my daily, or my wheeler - it seems

was more referring to Defender then D2 but Spanish steps where driven unlocked from memory except exit possibly though ATB is obviously still there... so far in neither vehicle I have been stopped because of to little flex. However in D2 I would not mind having longer travel shocks as I only use it for play..

Tassy trip was good example MLD with quite a bit more flex in his 130 then I have in 110 however on exit of Sawback I guess I had more airtime then he had but again 130 is also different wheelbase.

in my opinion I don't think flex will be a limiting factor whether I can drive something or not unless we talking comp trucks and rear pull down winch etc.

Car is certainly capable as is, but it's not flexing as I expected.















Keen to see others feedback, Wayne? How are your arms going. I know you have what looks to be more even flex, where as mine seems to flex the rear way more then the front in all scenarios now.
Have just fitted 250lb rear springs in place of the old to try stiffen the rear and force the front to work harder, will post results when I have them.


Also Greg? any news on the 3" version?

Hi Grimace
My arms are still going well.
Haven't been out for a long time though,took my 130 to Tassie,so the 110 sat in the yard,and been busy at work ever since.
Will probably sell the 110 soon and concentrate on my 130.
I could also easily get more flex from the rear,but prefer to limit the rear,to keep F&R more balanced.

Having read this in full a few times this is what I get out of it by using the Superior Arms, but I could be wrong.

The Advantages are extended life from the Bushes due to they are larger Bushes in the STD Superior Arms over the Rover Arms and a bit more life again if using the Superflex Arm on the passenger side due to even a little less stress again with a extra Bush.
Flex range is determined by the shocks open/closed lengths more so than the arm Bushes its self but larger Nissan bushes may help a very small fraction.

Disadvantages due to the weight of the Arms,
Off Road probably nothing much with the normal slow driving we do so-long we keep to the same º angels?
On Road maybe Braking distance will extend a fraction longer, slower response times of the shocks with pot holes/corrugations with faster driving?


So how is my understanding of it all and have I missed something while learning on the way?

I have warn through two sets of chassis bushes in last two years with superior arms. First set came with arms second set were rover ones. Rubber ones - tears them lengthwise. Poped one rear one over washer and nut. Not sure why but never had an issue with rover arms.

More weight on the front should help traction and decrease brake distance if lock up is avoided...

Bush ware at the chassis is likely to be increased due to the larger range of movement now offered by the less restricted nature of the axle bushes and arm design.

heavier arm will be a harsher ride but could be tuned somewhat with shock valving. The fact a person is running these arms is probably going to go hand in hand with a spring lift. This changes the front arm angle, which in itself leads to a more harsh ride.
