with 3.42s he is going to struggle up hills and probably fry his tranny or something.

he needs to change gears for sure if he is going to be pulling 7600 pounds. might as well do 4.10s

we used to pull a 7800 lb travel trailer(28 foot) with our expedition and it did ok, but that 5.4 had more low end than these 5.3. and we had 3.73s. any higher of a gear and no way we could have pulled it.

cant be too cautious with trailers. always better to have too much truck than too little.

i vote gear change or smaller trailer

Definately swap the 3.42s for 4.10s regardless of whether the Tahow will see any hills. Problem w/ the Tahoe is the short wheelbase. Shorter=less stability but the 5.3=decent hp/tq!

Sign up here and you can download the ownsers manual in PDF format and it will give you a matrix of towingcapacity by chassis/engine/gears for that year.

Here is GMCanada link to figure out capacity.
http://www.gmcanada.com/english/truckguide/pick_trail_capacity.html


I don't know on tahoe, but should be within capacity of a 1/2 ton pickup. If it doesn't have a tranny cooler I would add one. I assume you will be using a weight distributing hitch also, that I believe is necessary.

If you plan on towing frequently I would look into 4.10s (as others have stated). Driving empty might hurt mileage a little w/4.10s, but towing will be worthwhile. At least a 3.73, that might be a good compromise. You may want to look into some helper springs if the rear end is sagging too much. That doesn't increase capacity but will keep the sagging to a minimum.

 

[HBjeff]

oh the sagging.........i forgot about that. tell him to look into some helper air bags for the rear. they can be run empty to maintain a nice ride all the time, then filled up for the trailer. definatly cool.

i agree that 3.73s are a good compromise, 4.10s wont lower mpgs that much while empty. tahoes come with decently large tires(30inch). and for the cost of the gear change, jumping from 3.42 to 3.73 he would probably not feel much of a change at all. 4.10s cost the same........ :bowtie:

 

[jebx]

I just looked up current tahoe capacites:
http://www.chevrolet.com/tahoe/specs.htm#trailering

Looks like 2wd w/5300 3.42 rated 6700#
3.73 7700#
(4.10 isn't a factory option on 2wd)

Worth noting....

1 Maximum trailer weight ratings are calculated assuming a base vehicle, except for any option(s) necessary to achieve the rating, plus driver. The weight of other optional equipment, passengers and cargo will reduce the maximum trailer weight your vehicle can tow. See your Chevy dealer for additional details.

NOTES: Trailer tongue weight should be 10 to 15 percent of total loaded trailer weight (up to 1,000 lbs.). Addition of trailer tongue weight cannot cause vehicle weights to exceed Rear Gross Axle Weight Rating (RGAWR) or Gross Vehicle Weight Rating (GVWR). These ratings can be found on the certification label located on the driver door or door frame.

 

[BuiltNotBought99]

He should be fine

 

[coonbottom]

it will pull it..maybe not fast but it will..
If he is only going to pull it once in a while..dont worry about the gears but if he pulls it alot then 3.73's would be bout right
I would be more concerned about stopping it! That is alot of ass behind the truck. Make sure them breaks are working good on it.
