Better starter, gear reduction or high torque?

I'm looking for a new starter and was wondering which would be the better starter, high torque or gear reduction. I'm looking for the pros and cons if you've had any experiance with either of these or another kind you liked better than these.

I know its an old post but....for those who perform a search, Ford starte using gear reduction starters on windsor engines. In order to provide more torque to get our motors started.

The gearbox on the starter reduces stress on the starter motor thus helping it last longer while acheiving good function.

I have the gear reduction starter on mine and am pleased. I bought it off Ebay and have had no problem with it at all

Mitsu is gear reduction. I used to rebuild them all the time. As far as high torque goes...they are all high torque. The newer ones are anyway. I found that with the Race car starters, The difference in the torque was the sticker on the side of the starter. Old trucks and tractors had low and high torque as well as 6 volt and 12 volt systems.
I like Densos are great but the gears in the mitsu are beefy-er.

Biggest Pro with a Denso is MOST of the time the switch will burn before the starter motor does in the event of a sticky ignition. IF you can shut it down quickly but you do have a few more seconds before the whole thing is toast.

One of the problems with IDI's is the slow RPM of the factory starter. I bought a replacement starter a while back, I think a couple of years ago, from DB Electrical. It spins the engine faster making it easier to start and the price if I remember wasn't as high as rebuild from NAPA. DB has (or at least had) a website. I've experienced no problems with this product!

Originally the stock starter spun the motor over just like a new one will.

Starters slow down over time.
The slow down happens over such a long period, you don't even notice it.

Then when you install a new one, you notice man this is cranking fast.

If you have put enough miles on the truck that the starter has been replaced before, you suddenly remember, wow, I remember when it used to crank like that.

On the other hand, I've read opinions that the Mitsu can handle lower battery voltage, while the Denso does not like that one bit and will commit a "thermonuclear meltdown" suicide. I have a Mitsu in my truck and I can vouch that it will fire up the engine with low batteries times and again, provided there is still enough juice for it to turn over a few times after the plugs have done their thing for 15 seconds or so...

I will second that LCAM! I plowed the lot at work this morning. When parked the truck I let the plow down but forgot to flip the switch back to center. That soleniod was on for about 9 hours. When I hit the gp switch my the volt gauge dropped to under 10v. when I hit the key the gauge was at 11v and she still turned fast enough to fire (thankfully). I would have never lived it down if I would have needed a jump!
