Rear hitch height

[in-jack]

My 99 Tahoe seems to have rear sag.
I bought this used and it had an electric brake outlet at the rear leading me to believe that it pulled a good sized trailer.
My headlights, without a load, are set too high as I get a lot of oncoming "blinkers".
What is the consensus height of the underside of the rear bumper or hitch?

Thanks

someone probley put on a hitch and no towing package.
The vehical should sit level. With a towing package it will sit a little higher, 1/2 or so.
The added suspension in the rear weather it be with leaf springs, air shocks, over load shocks etc. will stiffen up the ride yet keep the vehical close to a standard height.
Bottom line is. The vehical should sit level with out a load.
How many leaf springs are on one side?

If it's rwd, it may not be level. A lot of rwd trucks are "raked" from the factory (lower in front). If it's 4wd it is probably very close to level.

A lot of smaller trailers have electric brakes too. Even if it had a huge trailer on it, I don't think it would permanently sag the rear springs. One of my relatives loaded his truck to where the rear axle was resting on the bump-stops and it didn't do anything. If the truck looks close to level, I'd just adjust the headlights.

According to the glove compartment listing, this unit does have the trailering package.
I will count the leaves today and post back.
The advice about having the headlights adjusted sounds good.

I would replace the leaf springs . your vehicle probably towed a trailer with too much tongue weight. rear with no equiptment in vehicle full tank of gas should set with rear slightly higher, than front. i would do this not because of my headlights being too high. it is because of tire wear problems/handling issues........
