Custom Radius Arms for the light duty 70 series?

[AdamReed KZJ78]

The kit I’m showing is the proper way to lift a prado 70 series. It is to prevent the car steering behaves like normal.

Hey Tsvigo,

You seem to have some good knowledge on the proper way to lift a LJ78 and get it to flex.

I'm wondering if you could help me out here, Im in Australia and have owned my 1994 KZJ78 for 2.5 years now and I've just been running the standard 2" Dobinsons lift kit with castor correction bushes. The amount of flex (Or rather the amount it doesn't flex) is really starting to annoy me.

My suspension is sagged and I'm just overall not happy with how the suspension is.

Can you tell me what the best option is to do the following:
- 3" lift
- Make the thing flex in the front and in the rear whilst maintaining some on road performance. When i travel i have a rooftop tent on, so for when I'm running this setup some stabilisation would be good

I have read through this forum more times than i can count and i cant find a direct response on what to do. Some links to products would be good.
These cars were never sold here in Australia so there is very little information here about them.

I would really appreciate the help!

Getting a lot more flex is not hard and doesn't necessarily require new radius arms (although they are good to fix geometry).

You have to do two things for good flex on an LJ78:

- Remove front and rear sway bars completely (looks like you have already)
- Replace bushings in front and rear radius arms with softer ones. Toyota put super hard OEM bushings in, and they really resist flex by a huge amount.

I guess third thing might be to make sure your spring rates are not too high also.

This kind of bushing works good and fits back/front radius arms (but they do wear faster than hard bushing.

That’s the problem that what he is having now. Bushing wear faster.

What bushings are you running ?

For mine, I’m using Siberia standard bushing with my longer arms.

What brand bushings are you running ? Thinking about taking my KZJ73 to the Rubithon and don't want to urn it in to a crawler but would like to improve the suspension a bit . Seems we are still nowhere on affordable arms these days .

They were nothing special; just ebay stuff. I had a look to see exactly which kit and I think it was this one that I'd bought: 8pce Front Suspension Offset Castor Radius Arm Rubber Bush Kit for Landcruiser | eBay - https://www.ebay.ca/itm/123423354617

I'm pretty sure 80 series ones work too. So that opens up options quite a bit.
