1997 tow package

I have a 1997 SR5 4runner and was wanting to put a hitch on it. I'm aware many came from factory with one but was wondering if there were other mechanical differences like a different transmission cooler or gear ratios. Any help would be greatly appreciated

 

There must be a difference I have a factory SR5 Limited..... So I got all the flares, wood grain, and options of the Limited. But also the “heavy duty” of the SR5 but not sure of the upgrades???

 

I gotcha, I mean I'm not planning on pulling insane amounts of weight or anything. Just wanted to know

Thank you, sucks I can't read it

 

My son has what my mother said was a factory installed tow package that I think has brake control in a box screwed to the dash under the steering wheel. I want to detach it, but not sure if that will mess things up.

 

A box like that, if it has a lever is probably only routed through the rear trailer hook-up harness. It would allow manual actuation of the trailer brakes for trailers that had active brakes.

I'm kind of doubting that would be a factory thing. In 2002 the "tow package" was a tow hitch and a gear ratio. If I wanted to support actuating rear trailer brakes I would have had to add or have the dealer add one of those boxes. Many dealer add-ons are viewed by buyers as "factory"...the dealer likes it that way.

 

What would the "tow packed" ratio be? Compared to the standard ratio?

 

4.10:1 vs something lower which would have given a bit less torque but better mileage. I don't know if it was for all years. I just remember the Toyota salesman telling me that in 2002.

Looking it up...it was SR5 "Option Package 2".

 

Oh that's cool, I put a 4:11 in a f250 I had, a little preppier than the 3:08 that was in it

 

If you have a 3.4L engine and an e-locker from the factory you have 4.3:1 rear differential

I do have a 3.4 but unfortunately no e-locker

 

The you have a 4.1:1 differential

 

4.1? Would that be the same as 4.10?

 

yes. 4.1 is the same as 4.10
