Re: Does GM 3.73 gears fit a 1993 jeep yj?
If you have 35s, you need at least 4.56s. Whether the 3.73s you have fit or
not makes no difference, they are not significantly different than the 3.07s you have -- and, you could already have 3.73s anyway. <chuck_is_the_god@hotmail.com> wrote in message news:1180380066.889841.239300@k79g2000hse.googlegr oups.com... >I have a 1993 Jeep Yj with a 3.5 inch BDS lift, BF Goodrich > 35x12.50x15 mudders. i need to get this into 5th gear on the highway > so my qustion is does GM/ford 3.73 gears fit in 1993 jeep yj?? > |

Re: Re: Does GM 3.73 gears fit a 1993 jeep yj?
This is so bizzare but coming from Mike it is no surprize. He projects
himself as the macho 4 wheeler Jeep expert,runs bigger tires with tall gears and says solution is to forget 5th gear and then Bill agrees that is less strain that way without even thinking about the extra strain that big tires with stock gears add to complete drive train in EVERY gear. You guys gave me a good morning chuckle! Also this logic of yours reduces power or wheel torque that you can get to the ground which shows you are 4 wheelers in ego not in practice. Getting back to orginal post, Chevy gears will not fit a Jeep and even so a 3.73 will not solve problem in OD with 35's nor would 4.10 most likley. A 4.56 would though. There is a mind set with some that a 3.73 or 4.10 is a great overall gear but the proper gear ratio depends on the tire size, vehicle and engine no one gear does all though some think they do. A 3.31 is a very poor gear choice for any off roading with stock or especailly larger than stock tires. Anyone that really knows their stuff would know this and fix it with proper gearing unless their ego is bigger than their understanding of all it how works. Proper gearing would give you more performance in all gears, require less usage of low range, reduce driveline strain and likely improve MPG too because engine will lug less but there are those that think the lower the RPM the better the MPG and lower the overall strain. If you vehicle requires 60 HP to cruise, it has to have 60 HP regardless of RPM which means with tall gears it has to work even harder at a lower rpm to cruise when you install bigger tires plus bigger tires add more drag for rolling resistance and extra drag from taller vehicle which means that you reall need to do more than just match effective gear ratio (old ratio and tires vs new ratio and tires) if you want it to perform well. You might look at the following charts. This first one shows the effect of axle ratio on wheel traction http://forum.snoman.com/viewtopic.php?t=63 This next one show the loss of effective pulling power or wheel torque at contact surface as tire size increase without a gear ratio change http://forum.snoman.com/viewtopic.php?t=53 This last one is a tire size and axle ratio calculator that lets you compute you engine RPM in drive or any gear that you know the ratio for. http://www.snoman.com/HTML/axlecalc_5a.html There are two basic groups of 4 wheelers, one group that thinks they know what they are doing (Mikes Group) and give up gears on trannies and run low range a lot and reduce over all performance and traction of road because they think axle ratio gearing does not matter. And when tranny or clutch fails or drishaft breaks or Tcase goes south they blame it on poor design not improper application by them. Then there is the other group (not one Mike suscribes too) that fully understands the big picture how important proper gearing is and takes the time and expense to regear vehicles properly (rather than hoping for air intakes and exhaust modes to "fix" problem) and then they do not have tranny, drive shaft or Tcase failures or power loss and they also get to use all of the gears too as well as have a vehicle that preforms better too on and off road.

Re: Re: Does GM 3.73 gears fit a 1993 jeep yj?
Sno Ball,
Mike and Bill have been here a LOT longer than you and have both forgotten more that you will ever know. Let's not forget you discovered this group while Usenet-stalking Mike, because he called you on your -------- in another group. Over in alt.trucks.ford you are almost universally disdained for the idiotic advice you provide. If you can, provide advice without the crap. Until you do, consider yourself plonked.
