Caster correction kit - necessary?

Generally a 2" lift will reduce the normal caster by about 2 degrees, so if you know what it is beforehand you will know approx what it will be when lifted. The CCK may be needed to return the caster to 4 degrees or more.

I'm not a fan of ARB shocks, just an opinion after having three sets on a 60 series which noticeably lost their mass controlling ability after 30,000km. Poor value I reckon. I had the trust in them, not anymore. OnlyGlorified Monroe shocks.
They never leaked and when hand tested they seemed ok, just didn't control the suspension rebounds.

You can buy many other brands and they won't be worse.

Every vehicle is different they won't know if it's required until the lift kit is fitted and if it needs one it should be fitted. I had a GQ patrol with 2" lift and didn't need the caster kit but my neighbours patrol needed one and oddly enough he didn't have a lift kit fitted just standard springs. $600 is a bit expensive when you can get the caster correction bushes for around $100 and a full kit replacing suspension arm bushes front & rear with a 2deg caster correction kit from $200 to $300

What people don't seem to realize or consider is: the increase in angle of the front arms is the same angle which is lost from the caster angle. Why would you not consider restoring it to correct?

If the lift causes 3 degrees increase in the arms, then the caster is 3 degrees less.

Just because it doesn't seem to be a problem and nothing can be felt isn't an indicator there is nothing wrong. SUDDENLY the situation can change and when conditions are right to cause a severe oscillation or wobble of the front wheels which can be uncontrollable.

To have it within specs is a sensible thing to do.

I love all the stories of "I gotta 3" lift and no correction and I don't have a problem", YET.

Don't let people confuse you by bring 3" lifts into the conversation there a completely different set up and require more modifications. A 2" lift generally requires just springs & shocks but quite often a caster correction kit but not always it's a case by case thing if you go to someone who knows what their doing they will let you know after the kit is fitted

Maybe call a couple of 4wd suspension experts rather than ask opinions on here?

Hi Craig,
I fully agree with the last post - ask around a few reputable suspension outlets and see what they recommend.
Now I got my 2" suspension lift installed by a 4WD outlet that had done many '79 series 'cruisers and they recommended the caster correction kit. I trusted fully the installer and went with their recommendation. My gut feel is to go with the CCK but get some advice by the people who do this for a living.

Good luck! Cheers, Geoff

Hi Craig,
I have a 76 series wagon to which I fitted a2" tough dog kit to and was told by Opposite Lock that they have never fitted a CCK to any of the 2" conversions only over 2". I found that the car wandered and tram tracked quite noticably and when the camper was on it was really noticablle.
The caster gives the wheels a shopping trolley like effect and if that is reduced it casn cause these type of issues, I went back to Opposite Lock and they said to bring it back and they would put 2 segree bushes in itand that would fix it, not satisfied I went to a steering specialist and had them do awheel alignment and the caster was out 3 degrees so I had then fit them. The vehicle now steers noticably better loaded and empty keeping in mind that the 76 series a fairly light in the steering anyway
Cheers Jim
