4.10 GEARS...CAN I GO ANY LOWER WITH 1/2TON CARRIERS?

[JRider]

Is there 4.56s for 1/2 ton carriers?

thanks,
JRider

not as standard from CHEVY......

I do not know this for sure but some have said the the 4.10's are weaker than the 3.73's and if you go to a lower gear they are to weak and break very easy.

You probably will have to check with a specialty shop that deals with the install of the stiffer gear sets.

Maybe an offroad or 4X4 site of some kind may have your answer.

Sorry

something to consider is if the tranny could put up with the added gearing.......it is kinda at the top end of its capabilities moving our AVYs around......

Would be a lot less of a load on tranny with tall gears. Especially if running larger diameter tires.

4.56 or even 4.88 would take a lot of strain off of the whole drivetrain.

Have you ever ridden a 10 speed bike. Takes a lot more pressure to get moving while in a higher gear.
Same goes for the mechanical components of your vehicle.

true but now the tranny and engine will be at higher RPM for same speed......I dunno you may be right but I am worried about my tranny.....as I see it as the weak link of the truck........and well I want it to last long long time.........hehehehe

orboater is right...the lower gears would, if anything reduce the load on the transmision. Heat is what kills automatic transmisions, the weak link is the clutches...burn them and you are done. The lazy shifts of the Av cause slipping which causes heat. Try running in tow haul if you are worried about your tranny, it firms up shift therefore there is less heat.

Other things kill auto trannies...hehhehehe like too much torque......

Thus the torque managment system.......

IMO...YMMV.....seek doctors help...3/4 dentist agree to agree......

 

[JRider]

You are correct...however, the 5.3 is anemic in the torque department in the first place (partially due to TM system)...and changing the gearing still does not change the torque of the motor. If I dropped a big block in I would be worried.

The larger diameter tires offset the difference in RPM and vehicle speed.

When installing larger diameter tires you are infact altering the final drive ratio. The taller the tire the final ratio numbers are reduced. Going with a higher numerical drive gear ratio only acts to offset what the bigger tires have caused. No difference to the tranny whatso ever.
