Any ideas on what I should do to my 98 4runner to increase my towing capability ? I have a 24' travel trailer that ways 5000 lbs on dual axels. My runner already had the proper tow hitch. Have 3" rough country lift kit and air lift in rear coils. I know I will need trailer brakes probably? Can anyone think of any other goodies I can slap on her?

 

You need a tranny cooler. A big one. Tundra brake upgrade, supercharger, or just go get a 4th gen with a v8 lol.

 

Lol. I like the look of 3rd gen. Too much. The ideas are good though.. Haha

 

You will want a brake controller and trailer brakes though as you mentioned as well. You are at the towing limit.

 

I have towed ~8000lb with my 4runner before. It was not fun but it did it.

5000lb is not so bad if the trailer is aerodynamic at all. I have towed many a car with that kind weight with mine and no issues.

Tranny cooler for sure. Turn off overdrive, load the trailer properly, and give yourself plenty of braking distance and you should be fine.

Supercharger would be nice but when I towed the 800lb+ load it was NA and did it fine as long as you didn't want to go much over 65mph.

 

I'll second trailer brakes. Prodigy makes a nice controller. As long as you aren't in a hurry, and you shouldn't be, you should be fine.

 

You going up and down any hills or mountains?

I'd say the Tundra brake upgrade, and transmission cooler for sure. Not sure what your budget is, but a supercharger will make things easier as well.

I was going to suggest airbags in the rear to keep things level, but it looks like you already have that covered.
