Thats correct , I could see 250 owners with 6 speed wanting the 430 gears

You wont know unless you start a group buy and do a market survey for the 430 gear assy

Note :

Iam in process of doing cnc alloy gopro mounts for wingtip and rear tail for spec aircraft that owners asked me to mfg

The will replace the oem tiedown assys I produce and can be removed easly.

With 4:10's being the usual selection for automatic trucks and 4:56's used by most 6 speed owners, I doubt there's much interest in 4:30's in the 6 speeds. And, as Topspin stated, low production numbers and a resistance to modify severely limits your marketing opportunity. Keep in mind, while some of us have done gear swaps, most SSR owners are not keen to the idea. I bet you'd be lucky to find a dozen takers. Now, if you can find another vehicle application that could use this gear set up, that may change the dynamics.

Before reinventing the wheel, if I am not mistaken the rear end in either six speeds or automatics are the same as used in other GM and possibly even other manufacturer's vehicles. Eaton in Trailblazers & other truck based Chevys & GMCs, Torsen in Camaro/Firebird & even Mustangs. Are we sure no one is currently already doing a 4.30 gearset for one or the other of these?

Summit Racing shows to have one 4.30 set for an automatic(small diff) in stock. Motive Gear performance set, part #G885430 for $264.28. In the Motive Gear standard sets #GM10-430, they show eight at $251.95. This is what comes up in a cursory search of their site by typing in an SSR, but the references are kinda light on detail so I think one would have to call them about fitment. 4.30s are out there it would seem.

There is another potential application which is the Trailblazer SS. It uses the same 9.5" axle as the SSR 6 speed. The TBSS came stock with 4.10s - wish that ours came that way from the factory!

The 4.30s shown are for the 8.5" axle found in auto SSRs. There has never been 4.30s available for the 9.5" axle found it the 6 speed Rs. This recent discussion is only about the 9.5" axle.

I went with 4:11s for the same reason. If 4:30s were available for the six-speed, I would have gone that route. 4:30s would work well.

Right you are, there's a big difference between the .70 overdrive in the autos and the .56 6th gear in the stick version! The autos end up with a 2.61 final drive ratio, while the sticks are at 2.09. When you swap to 4.56s, in a stick R, you end up @ 2.55, higher than a stock auto version! So personally, I wouldn't consider a 4.30, even if available for my 6 speed.
