I'm still debating the 63" Chevy swap myself... I may install the 3 pack AAL I have had sitting in the garage, remove the overload, and throw in the Marlin Crawler U-bolt flip and see how I feel about it...
I understand the draw to Chevy 63s, speaking from experience here! But if I were to do it again I'd have a custom set of progressive stock length springs made. Obviously I have a T100 so the shackle mounts are entirely different but I mean after you put together the parts, buy the springs, and the time involved tacking for placement you'd be better off having custom packs built for you. I like the flex I get from my Chevys but I've seen some killer flex from some properly built springs too.
Theres also the option of a shackle flip for extra droop. It would still be a lot of work but then you wouldn't have to mess with new front mounts and axle location. Also not sure how much lift that would add, but don't have to run a long shackle either.
Just some thoughts!
Sorry Addison for the thread jack!
How in the hell...im shocked a 16'' coil fits...seriously.
You guys are sure that the block height of the coils would allow that??
I phoned in and had the sway away tech check through the whole setup i think the info is in my build thread.



No problem. I;m still debating what to do here.... custom leafs @ factory length with shackle flip or 63's. Problem with the shackle flip is it's kinda hard to build a custom leaf pack until you have the shackle flip done and know where your limitations and ride height are. I might just flip the factory pack and see where I'm at, because I will have to do it for the Chevy's anyway and the front hanger is the one that moves.
Nice job on salvaging the tabs to mount the liner. I just completely did away with it, which is another reason I did the undercover cowl snorkel.
Do you need to trim the rear fenders as well? If you trim more than 1/4" off the rear wheel well, the inner and outer fender walls will separate and you'll have to devise a way to keep the bedside from flopping around. I made brackets and welded them on. In the process I "pulled" my bedsides about 1/2" just because I liked how it looked. If you can avoid all that work because your tires aren't rubbing at full compression- might as well.
aren't Tundra springs around 58" long eye to eye? So is the extra 5 inches of spring really worth the added hassle for what would be minimal droop gains? I'd think you would see the most improvement from the shackle flip.
Not too mention the spring rate of an unmodified Chevy spring pack isn't spectacular
