Hello guys, I am going to buy 5.29 gears for my IFS 91 sr5 V6 toyota pickup, I know which set to buy for the front because it only has to say 7.5 and needs to have 23 splines, but I do not know which ring and pinion buy for the rear. I do know that is has to be for a toyota V6 but how do I know how many splines the pinion must have. I have seen on the web that they sell 27 and 29 splines ring and pinion sets, for example the YUKON guys sells 29 splines and they sell an adapter yoke, but just to be sure do you guys know how many splines does the 1991 toyota pickup v6 sr5 has on the rear pinion? and do you recomend a specific brand for the sets?does the ring and pinion sets comes with a kit with the bearings and stuff?

 

also, do you runrear lockers on a daily driver? is it safe? does it affect too much on the highway? which locker would fit my my rear axle? which would you recommend?

 

Don't know for sure whether your diff has 27 or 29 splines on the pinion. I'm a bit more versed in the 4 cylinder diffs and the E-lockers. I do know that you can use either one as long as you have a matching flange and seal. This is a bit extra cost, but possibly not a bad idea. Your original flange may have a groove worn in it by the seal. Yukon is good stuff. If you're looking to pinch pennies, try to save up for a Yukon in the rear then buy a cheaper set for the front. Depends on what kit you buy whether you get the bearings or not. USA Standard Gear is a good cheap brand for getting bearings and setup kits but they have always come with KOYO bearings which are considered top of the line. They are OEM.

I run a Tacoma E-locker in my 4Runner. It's what I would consider the best because it's fully open for the street and fully locked when you hit the switch. No affect around town at all. Since you are asking how a locker affects on-road driveability I'm assuming your talking about a lunchbox or auto locker of some sort. I don't think anyone would claim these are the best option, but they do work off road and they are a lot cheaper. It's up to you. Highway driving is the least of your worries. That's when you'll notice the locker the least. The thing to worry about is turns and curves where an auto locker can lock and then cause you to slide. Sure you can get used to it and learn how it behaves, but it's still something you're not in direct control of.

Also, just for your info. I have a complete Tacoma E-locker axle for sale if you're anywhere near Virginia.
