What gears for towing
 
What gears are good for towing my buggy its like 2000lbs or less i have 33" tires and last time i towed i over heated bad so im switching to a 3-4 core radiator but i still think it needs different gearing

What engine/trans/current gear ratio? What truck is it? The more info you give the better answer you get. :)

Engine-388 stroker
Trans-TH350
Gears-I think 3.23
Truck-85 chevy c-10 step side
Seems when i had 4.11 gears it towed better but i cant seem to find them cheap so maybe 3.73?

I suggest 3:73 because you dont have OD. Get Yukon brand gears, better than stock and great quality.

With the 33's 3.73 will run about 2530 RPM at 65 MPH and the 4.11's about 2780. However I would check out the cooling system first, make sure there is no other problems before swapping gears. It shouldn't overheat as it sits now, a 2000# trailer isn't a heavy load.

Yea, I tow a popup camper with my Jimmy 4.3. Weight when load with gear is close 2000 lbs. The 3.42 gears do okay on the highway. 3.73 would be great overall gear.
