Speedo Gears 200-4r

[LCAC_Man]

While I have my trans out I'd like to swap in somespeedo gears that get me at least close to my combo. I've looked at a couple of the calculators but I'm unsure as to what tooth count gears are readily available. I'm running a 27.8" tall rear tire and 3.73 gears. What would be the closest available speedo gear combo for this setup? Where can they be had?

Imo

A 28 in. tire and 3.73 gears puts you right at where the factory speedo gear are closest. Factory is 26 in. tire and 3.42 gears. Don't believe any other gear combo will be any better than the stock GN orange drive gear and the blue 30 tooth driven gear.

Is there a source for the Blue 30 tooth driven and orange 11 tooth drive gears? Looks like the 27 tooth driven and 10 to drive could work as well.

I dont think there is a 27 driven available

Looks like TCI & Summit have the 27th driven gear. MonteSS's came with 3.73 Diff. gears with 10th green drive gear not sure what factory driven gear or tire dia. was.

That looks like the combo I'll go with, it appears that the 11 tooth gear is hard to get.
Nice chart on available gears and combos:

They seem to have about the best price ($55 for the drive gear, $14 for the driven) that I've found.

Check Chris's site ckperformance.com looks like his prices are lower for either combo of gears.

CK's are cheaper than TransCenter Or try Bulkpart. Email for prices on gears.

Bulkpart replied back that they don't carry them. Looks like CK is the place.
