Re: Leaf spring question

i would think about doing a beg ten conversion. in 77 (and other years also) chevy built a big ten which had beefyer 3/4 ton rear springs and bigger brakes over the stock half ton. it was perty much the ultimate towing package for a half ton. the big ten had the 3/4 ton springs, 1.25 inch wide front rotors compared to the stock 1 inch, had 11-5/32x i think 2 1/2 inches wide shoes in the rear, and came standard with a 3.73 gear ratio in the back. my truck and trailer weigh about 6000 pounds and we put a 6000 pound john deere crawler on it and it didnt have a bit of trouble. but i do also have helper springs on my truck now and they help some to.
