Thread: Superior Engineering Superflex arms for Rovers.

Steve, I lot of Land Rover nuts are running extended shock mounts front and rear so as to correctly fit longer shocks.

Those user that are running longer shocks with mounts to suit do get a lot more travel especially when they run spring to suite the load they are carrying front to rear and if they match the spring length etc etc (plenty of opinions out there).

Biggest issue with land rover suspension that everyone has had whether its running stock length spring or not. The front radius arms restrict articulation and cause the rear end to do most of the work. Hence the truck becomes very unbalanced and dangerous off road (don't get me wrong Land Rover in stock form can go a long way off road).

If you go back and read all the posts in this thread you will see a fare few different suspension setups. A lot are great... BUT when you are cross axles and the front bushings are bound up the sudden weight shift can be rather scary or cause damage to trail or truck. This has been an eternal dream for drivers of Land Rovers, Patrol and land cruiser drivers that didn't want to go for a 3 link front end etc as any major mods to free up the front suspension has always caused the trucks to be dangerous on road.

The point of the Superflex arms is to gain the benefits of radius arms onroad feel and the safe better balanced articulation off road.

Their is plenty of other users on this board that can do a better job of explaining than myself. But have a read of this thread and photos explaining the different setups and hopefully you will get to a place that will allow you to work out your preferences and needs.

Wayne the pivot point and the length that the diff sits from before i fitted is a little better.

One thing to note my old arms were both slightly bent which could be why when I measured the difference the new arms allow the diff to sit about 15mm further from the pivot point. Looks like the arms is setup to be the same length as standard but cycle better without binding and wearing the bushes as quick at full articulation.
One of my old arms was bent more than the other... e.g. when I measured one side compared to the other a 5mm difference between the two (20mm and 15mm).

Thanks for that Nick,but I think this info was meant to be directed to Serg.

Ha.. yes it was Wayne.

Serg Wayne was correct. The length and Pivot comments were for you

The LRA article refers to increased articulation with retained springs - he refers to unretained springs or 'drop axles' as ' extremely dangerous'... which they would be, if you were going to jump the thing! Otherwise he's correct, long travel shocks are going to do S.F.A. if you only have 50mm of with lift with your typical retained springs.

Watching a comp truck with unretained springs vs a comp truck with long, soft retained spings (that would be completely undriveable on the road) look about as equally unstable in my eyes in off camber stuff, keeping a low centre of gravity is more important.

no way in hell my Defender would do 160km/h!





unless down a mine shaft

I was just thinking the same.
