I guess you could say it will be similar to the SD 3-link. It's a similar design, but it will be a more involved install. I don't feel there is a safe way to design a bolt on kit for the Toyota frame, and if there was, I don't think it would look good. But my idea is to jig the cross member off of the existing bed mounts. I have a cross member built that bolts to the bed mount in front of the axle to locate it, and lines up between the two bed mounts behind the cab. The wishbone will be similar to the one on my truck, but I am changing some things to improve the design and the geometry of the setup, and also make it look better IMO. I should have a wishbone wrapped up by Monday with pictures. Until then here are some pictures of the parts I have been working on.
First is the tank relocation brackets. The first one bolts to the front of the tank, moves it back an inch and up 3/4" so that it is above the bottom of the frame.
The second needs to be welded on to the frame in the notch area. I leave an extra 1/8" on it to be trimmed off, since some people will run an 8 piece notch, and some might run a 3-piece, which will make a difference in the frame thickness in that area.
And these are the lower link brackets on the frame side. They are designed to sit above the frame a good bit, and also protect the bushing from dragging.
And they will use the bed mounts to line them up. The stock spring perches will need to be removed entirely.
I've thought about offering them both TIG and MIG welded at a different price. The wishbone and links would be TIG welded in both versions, but everything else could be optional. I also want to offer it with bag/shock mounts that work with sleeve bags behind the axle, and a common size shock. Also just a shock mount for those that want to run bag over axle, or build a 5-link type setup. It's all designed to fit under the stock bed floor though, with minimal trimming.
As far as price goes, that will depend on a few things. I am going to have most of the pieces laser cut to knock down the time level, and I am already working on jigs for everything. I also have a kid working for me now that I can get to cut pieces based on the templates I have, so I can basically just assemble it myself and get it done faster. I'd like to keep it in the $900-1000 range with bags included, along with all the brackets. And maybe a $150 difference to TIG the remainder of the parts. I also might sell Bilsteins with the kit at a discounted price, because I am getting a decent break on them now. About a $10 difference from KYBs. I plan on using a QA1 rod end for the single pivot on the axle, and bushings everywhere else. But I am going to offer a pivot joint (nicer than the SD ones IMO, different company) on the lower bars for about $100 upgrade.
Does that sound reasonable? I will probably be ready to produce this in about a month. And I have worked out a deal with the local powder coating place that did my frame, to coat the wishbone, bars, and brackets that don't get welded to for $150-200 based on the color.
