Can you fit +5'' Shocks on Standard Height Springs

I want to Keep the standard height on my 90 but increase the Articulation. Is it possible to fit the +5 terrafirma Shocks on all four corners.

1) Would I need rose jointed trailing arms.
2) Can I keep the Standard radius arms as it is not lifted.
3) Would changing the A-frame ball joint be a good idea to help with articulation.
4) Would dislocation cones need to be fitted on the front axle as well as the rear.

It's currently has 235 85 R16 tyres on,

Any help would be appreciated

1) Would I need rose jointed trailing arms. No but cranked versions may be required
2) Can I keep the Standard radius arms as it is not lifted.Yes
3) Would changing the A-frame ball joint be a good idea to help with articulation.It may do, it would be worth doing it if it is showing signs of wear
4) Would dislocation cones need to be fitted on the front axle as well as the rear.With +5 shocks you will need them. I found that the reverse (axle mounted versions) were more reliable with long travel shocks

HTH, Harry

Cheers Thanks for your help.

+2" springs and shocks is what I would go for!!

standard chassis bushings can take 12" of travel from standard bumpstop height

But this isnt going to help your articulation!

Your running standard springs so your not going to gain any articulation, your not gaining any room to give yourself more articulation. Your axle is still the same distance from the chassis. Your tyres running into your inner arches will be the thing preventing your shocks from going to full travel.

To increase articulation you need to lift the bodywork away from the axle. The only way to do this is to lift it. Either lift the axle from the chassis thus lifting the bodywork or lift the body from the chassis.

Thats how i worked it out anyhow!

I ran 285/75/16 tyres on standard height suspension(Only an inch higher than your 235's) and i was eating the arch all the time on articulation.

That's not true. The axle will be able to DROP further, therefore allowing the wheels to be in contact with the ground more.

& the bump stop will stop it from going all the way up. It will be the joint's that stop any more travel & how big your tyres are.

One of the things often overlooked is the A frame, which limits downward travel, and I don't think that can be altered.

You can get a rose jointed a frame

If you fit +5 shocks with standard springs you will get much more droop travel! So yes you will need dislocation cones, you seem to be forgetting that the shocks in the compressed state will be longer too, so unless you raise your shock mounts you will bottom out the shocks before you hit the bump stops! It's more complicated than just bolting bits on

its not as simple as that tho. if yu rose jointed the front of the A frame, you still have angular limit that the rear ball joint can move in. Also its a function of the triangulation between the A frame and the trailing arms, as they are moving in different arcs.

I prefer high movement ball joints, or johnny jointed rear ends to rose joints

Don't matter cos he'll smash his shocks anyway

If you fit +5 shocks on std mounts you will get nowhere near the bump stop the shock will top out before so you gain less upward travel (Bad idea upward travel is important for stability plus you WILL bend your shocks) You may well gain lots of droop however your looking at about £600+ to get it setup right where as std springs and Plus 2 inch shocks will not limit your upward travel but allow 2 inches of furthur droop. This means you usually get away with std propshaft uj's std bushes etc. the money saved I'd put towards a rear axle locker far greater improvment than just suspension with open diffs.

Summat like this!

If your in Bedford your welcome to pop down to the Herts laners (in Bedfordshire confusing I know) pub meet we hold every first Wednesday of the month in Dunstable everyone welcome can discuss furthur as plus 5 imo is a waste of money for 235 85 16 tyres
