BlazeN8's 1986 4Runner Build-Up Thread

"Leave it to Deaver"

I struck gold in my search for a "low buck" rear leaf spring for my 1986 4 Runner 4x4. I was looking for 3" of lift to match the front Blazeland Long travel. I was aware from word of mouth, and from browsing the internet, that Deaver offers a "long travel" Stadium leaf spring pack, but it involves a new 61-1/2" long leaf spring pack and requires some custom work to install. I suspected there might be some other options so I dropped by the shop. I met with Jeff Crosby the Spring Designer at Deaver. The Stadium spring pack (Deaver part #F67) would be awsome, but Jeff agreed it is little more involved and not a simple bolt on install. He had some other ideas for something less expensive and 100% bolt on to match the budget friendly Blazeland concept up front.
Enter in the Deaver "MiniPack" This is designed around the stock leaf springs. Jeff's plan was to dial in about 2" of lift by removing the overload leafs and installing a progressively decreasing set of smaller leafs. Then get another 1" of lift by installing longer shackles. It took Jeff a few days and some R&D on my 4 Runner, but it came out AWSOME. Read the write up on my install. Enjoy!

As with all installs safety first. A level surface, wheel chocks, an adequate range floor jack, and a sturdy set of jack stands is a must. Jackstands need to be capable of at least 28" height to support the vehicle by the frame, and let the rear axle drop out completly. What I am removing is stock set of springs with an add a leaf and a set of 2" spacer blocks. I have some respectable shocks, 5100 Bilsteins for a 4" lifted Toyota that I will be re-using. The shocks are long enough for drop out but are too long for compression without the 2" blocks and a bump stop spacer. New shock mounts will eventually be installed.

There are still some details for me to take care of like removing the parking brake extension brackets and adjusting the brake proportioning bracket. I will also be removing the additional bump stop spacers. At some pint I will need re-locate and install new upper shock mounts further up the frame. As it is now the shocks are acting like the bump stops (not a good idea) Stay tuned for fine tuning.

we need a video nate :)

Nice. What is the cost of the "low buck" spring kit?

The cost is as follows:

$196.00 MiniPack
$8.50 Front Eye Bushings
$6.38 Bushing Seeve
$22.88 Rear Shackle / Frame bushings
$52.80 U-Bolt kit
$25.07 CA sales tax

$311.63 Total

Not bad to freshen up an old set of springs, gain 3" of lift, and obtain a supper cush ride. I'll get back to you on the wheel travel measurments. The ride quality is excellent on the street. I'll have to take care of the shock mounts befor I can get a feel for how it performs on the trail and in the whoops.

Oh, I forgot to add in the cost for the extended length shackles. Since I built them, the cost was FREE. Well the cost for a 5 foot section of cold roll steel bar cost me $6.74 and I only used about half of it. I'll post some pictures of how I made the shackles in a few.
