Thread: BJ73 Landcruiser

Are these the parts I would need for a 50mm lift? Anything else?

4WDbits Landcruiser 60 10/85 On, BJ/FJ/HJ/HZJ/PZJ 70/73, Long Travel Rear Shock Absorber

Presumably need some bushings, shackles, u bolts also?

Also where's the best aka cheapest place to get some 33/10.5/R15 BFG ATs ? presuming they'll fit the rims


Also also anyone got a solution for a minimal bar that will fit over the PTO winch?

If you are going to do the suspension then it's worth replacing the steering stabilizer as well and if you are going to do that then you should probably replace the tie rod ends.

Bushings will need replacing. You can either go with rubber and standard shackles or nolathane type synthetic bushes and greasable shackles, the rubber ones shouldn't be greased. U bolts are also a must replace item (which also means you can just cut the old ones off) but the shackles should be ok assuming they are not damaged.

Don't forget to unhook the brake line before you drop the axle out. It's not called the break line for nothing.

Is a 3B grunty enough to spin 33s or stick with 31s?

The 33's will suck the life out of it. Went from 31 bfg at's to 32 mickey t muds and fuel consumption increased by 1.6l per 100, and a noticeable drop in grunt

That's good data but a shame

You have 8"? Diffs? You will be fine with 31's. Even more so if it's a shorty

Middy. I think the BJ73 has 8 inch diffs yeah. I need to make a trip to Palmy to actually pick it up.

Within the 8 inch diff there are different ratios being 4.11 and 3.77. I think 5.29 is available after market. You won't know which one you have without spinning tyres and counting turns. I put a new diff in mine at one point, wondered why it made so much noise off road only to find I had 4.11 in one end and 3.77 in the other.

I put 33s on my 40 and they are awesome. 3b should spin them I would have thought but 3b isn't way you would call grunty so you are not going to get anywhere in a hurry.

It's worth noting that a spring lift doesn't mean you can fit bigger tyres. When the suspension is fully bottemed out then you will be resting on the bump stops just like you did with the old worn out suspension. I had to extend my rear bump stops to fit 33s and they still rub on the inside of the rear mud guards.

Most of the 4wd club guys also do a small body life to help fit the bigger rubber.

you probably have the bigger 9 inch diffs. (a copy of the chev 12 bolt).
the coil sprung bundera/Prado's came with 8 inch diffs.
the later 70 series came with 9 inch in the rear & a 8 inch high pinion in the front, but I'm pretty sure these has coil front suspension.

New truck seems a pretty extreme alternative to replacing the clutch in your surf...

I always wanted a Landcruiser...

It's leaf sprung in the front

E: oh yeah you meant the 79 series, yeah they're coils up front

You will fine with 33's, yes its a bit slower, a bit more gas but nothing to drastic and you soon get used to it. I had a 70 with a 3f, went from 31's, then 33's then 37's and then back to 35's

The 37's were a bit over the top, never had to use 5th gear and you were never in a hurry to stop, but it made up for it with the approach and departure angles, and it looked cool on 37's.

Just like rifles, assholes and opinions, everyone has one... Just get it, drive it, enjoy it, the upgrades will come later. 70 Landcruiser's are the freaking best!!

This thing is not getting 33s lol


Love the wildly optimistic overspeed beeper at 105

Trucking well is it?

Haha, already gutless on 31's?
