Hey new to the forum here.
I'm in the process of budget building an 85 4runner. I've been searching around various forums and can't find any proof; other than word of mouth, that this is a decent rear spring setup. How would 51" Toyota springs compare to reversed F150? I was thinking that if I ran the 51s, I could orbit eye shackle hangers and add a couple leafs to match the OME RUF I plan to do. Any pics of a similar spring setup in action would be appreciated.

 

The best thing to do with spring swaps is trial and error. I've only used Toyota springs or after markets so I don't have a lot of experience. But I do have lots of friends that have done similar swaps. One friend would have success with a certain spring packs and another wouldn't. If you can get them cheap from junk yard or off craigslist then you can do some experimenting.
