As mentioned, I have many laps on all kinds of traction devices. Im 4430# without the driver. 700+ HP Fe with a TKX currently. Gear ratios are anywhere from 3:70 to 4:30 depending where I race.

 I have broken several TKO 600 transmisions, but never the rear. I have wore out the helical gear units, with many race miles on a road course.

 Part of what I do also requires some drag strip passes. I have to run a 200 or 100 tread wear tire, so not exactly like a slick. I do dump the clutch anywhere from 2800-3600+ depending on how the track is hooking.

 Would I run a Trutrac in a drag car on slicks? No. I always ran spools or lockers. Would I run it on a street car with a few passes per year at the drag strip? Yes. The street manners are really good, cornering is improved over any clucth type or locker differential.

 For what I do, so far the toughest and most relaible has been the Detroit Locker, although I sacarfice some handling in the corners.

 Every unit has its application, if its only a set of drag radials a few times at a drag strip per year, little or no road racing or auto -X I would recomend a helical unit just based on street manners.

Good for Summit Racing for doing the right thing.

I have a TKO 600, 26 Spline input, rem finished gears, cryo treated and fresh. 0 miles since a complete refresh. I have to double check, but I think it has the Ford FE short input shaft. I might be intrested in a trade. Where are you located?

I ran mine progressive for over 80K miles, also raced at the drag strip and auto-x. It was a very responsive setup that actaully did ok on MPG when just cruising.

Yes, 1 more the same as last time.

 Thank you,

Lars

Anyone intrested in another order? or does anyone have a 4.375 crank they would part with?

Brent, put me down for one with the short Ford input shaft.

Thanks,

Lars
