Yesterday I added some King 700 lb coils to help handle the weight of the bumper and winch. I also replaced the upper SPC ball joints because one of the originals had some play in it.
Going from 600 lb coils that come with the Bilstein 6112's to King 700 lb coils. Not much difference in height, same amount of wraps but the coils themselves are noticeably thicker.
Out with the old, in with the new.
Here's a picture just before I started with the 600 lb coils at the 4th notch up. The front dropped about an inch with the addition of the steel bumper and winch but it still rode surprisingly well but I wanted that inch back.
Here's a picture after the dust settled last night.
So after spending the better part of yesterday adjusting the 6112's here's some observations on swapping in heavier coils. To start out with, the 6112's at the 4th notch (and 1/4" spacer on the driver side) measured 22 5/8" from the center of the hub to the edge of the fender. The front dropped a full inch when I added the bumper and winch, which I expected. I didn't want to compromise the ride when adding the Kings so I first installed them at the 2nd notch up. Unfortunately, this resulted in the same height as the 600 lb coils at the 4th notch. I removed the coilovers and moved the C-clip back to the 4th notch. Surprisingly, this gave me about 1.5" over what I wanted. The front was high and the ride was rough as the coilovers were topping out on just about every bump. Third times a charm, I removed the 6112's and dropped the C-clip to the third notch up. This puts the front about 1/8" below where it was before the bumper. As long as the kings don't settle any, I'll be happy at this height. If the do settle, looks like I may have to fine tune with spacers above the 6112's.
Another observation, I thought about leaving the front sway bar off and drove the 4runner a little without it after getting the 6112's dialed in. To me, without the sway bar, it simply leans too much for my comfort. The ride does seem smoother but the lean seemed excessive to me. That being said, I re-installed the sway bar since I'll probably be adding an aftermarket roof rack and possibly a RTT.
The other thing I did yesterday was cut some new fender liners out of 1/16" rubber. Unfortunately I broke most of the retaining pins and the replacement pins don't seem to fit right. I dug through the garage and barely came up with enough pins and screws to install the new liners but they're on there!
