I have a few questions for the 40 gurus on the forum.:

Q1- Were 40s sold from the factory (factory base specs) with a slight rear-end sag? My 76 BJ40 has slight rear-end sag, about 1.5” lower than the front snd it’s beginning to bother me a bit. I’m running 235/85R16 tires with absolutely no issues.

I’ve seen a lot of 40s that are pretty level front to rear but they’ve been typically modified with 2-2.5” lift kits, usually running 33/10.5-15 rubber.

Q2- Wondering if my truck will level nicely and give me a little more height if I install a set of front/rear 2” or 2.5” springs.? Only installing the springs as I have new (factory spec) shackles/bushings and shocks that were installed about a year ago.





Your thoughts?

I’m sure it will level out nicely and give you the lift you want. You have to remember that a lot of hands have been on that 50 year old vehicle and there’s no telling what someone may have done or if they are just worn out original springs. Always nice to start with fresh suspension.

I have a leaf out of the rear spring pack right now because I was chasing a rear end wobble/vibration/hop. I will eventually do the same to the front to even it out but it really doesn’t bother me right now.

This has a 4” OME lift that is way too stiff. Removing the bottom leaf drops it to a 3” lift with a softer ride. If I was to do it again I would go with the 2” parabolic springs from Valley Hybrids.

Disclaimer: I’m not one of the gurus on here; just a guy that has entertained himself for the last 22 years with this Landcruiser.

You could go with a new 2.5 inch lift. Terrain Tamer @orangefj45 George provides a new style for leaf spring you might want to check out. Most likely though even with a 2.5 lift the ride will get stiffer. I would reccommend having someone simply install a long add a leaf to the rear springs to give them a little more support.
 
Are those 33” tires and (off topic) is that a SOR sliding window?

Yes on the 33’s and no idea on the window. They did have purple tint on them if that’s any help 😂

I always wondered where they came from.
 
For some reason your pictures didn’t show when I first saw your post. Beautiful BJ40. The weight of the hard top and accessories up top aren’t helping I would guess. Love the fish antennas.
