Hi all,

I'm pretty clueless with regards to reduction gears and things with gears as a whole. What i would like to know is whether it will affect the Jeep's engine braking ability in a positive or negative manner going down steep hills etc?? Or is that mainly up to the transfer case ratio or do they compliment each other?

Thanks

 

The lower gearing in either transfer case, differential, or both will increase your compression breaking. In the differential you will notice it on the highway if you use your cruise control, and off road. If you just do a low kit in the transfer case, then you will only notice it in 4wd low.

 

Your engine breaking will increase exponentially. Gears are basically letting your engine do less work while producing more torque the trade off here is obviously speed. Just remember the gears work both ways in transfering power to the wheels and from the wheels in an engine breaking situation

 

Thanks for the help. Think i'll get me some reduction gears for the diffs to start off with. Would there be any issues with warranties etc. I have a X model and i think i should go to 4:10 ratio as i will never go bigger than 33" boots

 

The warranty is more of a case by case and each dealership is different in how they would react to the gears and warrany. Technically they can not deny a warranty unless the aftermarket part is directly what caused the failure, so your gears won't affect the suspension warranty. However some dealerships are better at dealing with this than others.
