Can i increase my carrying capacity if i install heavy duty coils?
I have a 2002 Toyota Sequoia and it has coil springs all the way around. I was wondering if i merely installed some variable rate coil springs (so it still isn't like driving a rock) that have a heavier weight rating if i could load my SUV heavier. On vacation I carry 4 people, their luggage, and a small 14 foot pop-up camper. I'm using a weight equalizer hitch, and as it stands, i am maxed on the back axle and could carry 200 lbs more on the front. If i installed heavier suspension, can i expect my axle and chassis to be able to handle the extra weight? and how much more?
