i beg to differ on this point, for starters, from what ive seen of t series crown and pinion gears, they look like mild steel. 20 years old at that. If the techno pro spirit ones are made from stainless steel, or hardened steel of some sort, they will be 2 or more times stronger than standard, that said i have no idea what there made from
|
oh dear.. we didn't think that thru did we 
stainless steel?? 
all diff and pinion gears are made from (roughly) medium to high carbon, heat treated steel. stainless steel can be very soft, and doesn't respond in the same way to heat treatment as steel which does not have significant amounts of chromium or nickel.. indeed stainless steel usually has low amounts of carbon due to the chromium content....
i beg to differ with you. i do not think these aftermaket gears have significantly greater strength or wear properties. that said, advances in metallurgy in the last 20 years may have filtered down to gears, but they are not exactly a high tech item  so if they are better, it is only slightly.
it is highly likely they are made by the same factory as OEM parts anyway . the main benefit is that they are new, have not been shockloaded yet, and you get to wear them in properly.

but i certinally dont think that bigger is the only way to significantly increase strength. Just need the use of better materials. However - the next problem knowing u are running a kaaz (strong diff) is the t-18 axles, there matchsticks.
edit: Rodger, yeah it will be $600 or less, for a 4.5:1 = $411 + shipping, so more like $500 to your door. 4.3:1 = $500 + shipping, so around $600 to your door, only a guess, email greenline if u want real prices.

hmm, T18 axles are not that small, but with a 2 way diff that acts almost like a locker on both accel and decel... either the tyres slip, the LSD slips... or the axles break,.. choose 1.
given that materials of most available parts are of similar quality, bigger certainly is better, particularly with crown and pinion gears, spider gears, axles, etc... small things, which with a small increase in size, result in a much stronger part.
price for posting gears (that i sent from japan recently) was around $125 for airmail. also many japanese companies do not like to send parts overseas due to payment hassles... (or respond to english emails )
30,000yen gears on yahoo auctions = about $500-550 landed with no tax. duty and tax is another 20%ish...
