I take it that there is no IC adjustment with the kit. It would be nice if you could somehow be able to make changes to the lower bar angle to accommodate harder or softer hits needed by different HP, drive line setups and weights... which will want changes to the IC. Will the triangulated setup allow some preload from one side to the other like a parallel 4 link, ladder bar or Caltrack setup does?

The lower rear mount has 3 different locations allowing for some adjustment. Granted any bolt in kit has some compromises. The lower bar in front uses stock leaf spring pocket (bolt in). Ideally that would be replaced also with a few holes.

Of course then you give the user so many choices, setup can be more difficult. Again some compromises, but I will say I am very happy so far with how it turned out with those involved.

Ride height will obviously change IC also and may need adjustment.

The upper bars are tight location in order to have several different locations though without doing a whole rear frame swap type operation.

What were you using for shocks? And how much are they worth? I'd like to see some pics also, curious as to how much the exhaust has to be moved.

Re: Typhoon Bolt in 4 Link Success

Based on interest, I am fairly certain Hardman and myself will move forward with the next level of effort it takes to make proper production fixturings, final cad design of brackets, and refinements. It is always one thing to prototype something on one vehicle that is sitting in front of you. It is another to go into production and box up items to be installed sometimes in another country.

Before we went through that effort I wanted to verify there would be enough interest as it does comsume a bit of time, and I this isn't a pocket change modification for folks.

We have used some real nice bushings on the links (not a simple tube with poly bushing). All the bars have both ends threaded to allow easy adjustment, and this is a bolt in operation. Aside from 8 rivets your truck will be able to go back to stock. (I doubt anyone will, but it does allow for installation by anybody).

Obviously installation instructions are going to be needed also.

Right now the test truck is in cincinatti area undergoing motor work, but plan on a late this year early next year for the first set of kits to be available.

What changes would have to made for it to work with an 8.5 rear end

Basically a new rear cover plate. I do realize this might be an option for some and do have an 8.5" here I can use to make that an option.

How much work do you think you would have to make the changes to fit a SY. The 8.5 option would be awesome too, since I have both options to choose from. Can't wait to see pics. What matl were you thinking of using? CS or moly?

Re: Typhoon Bolt in 4 Link Success

I will make the 8.5" an option for sure. Can even be an upgrade later if someone changes after.

A LOT of misconceptions about chromoly exist. To be honest I have made the trans and torsion bar delete from chromoly tube purely because people asked for it and it sounds cool. There is no other reason.

Chromoly weighs the same as mild steel, the tensial strength of chromoly is ~90,000 psi where as mild steel is ~60,000 psi.

Most think of chromoly as lighter, but that only plays into effect if you use thinner material.

Tubing itself is not a big difference in price, but if you price out 4130 plate vs mild steel the change is dramatic. Then to take advantage of weight you go from say a 1/4" thick flange to 3/16", save maybe 1/2 lb, and cost just went up significant. I would suspect that 1/2 lb weight savings on our suspension can't be felt by anyone, the $250 more it would cost to build I bet would.

The sy kit could use the lower bars with not much change, the issue is the upper bars, will collide with the side mounted gas tank. So in order to keep the stock gas tank, the upper bars need a new design as well as new crossmember.
