Currently have 10 bolt axles. I am concerned about hurting the motor and/or transmission with my 35" tires. I am concerned because my gears are only 3:73. My motor is 350 w/ rv cam, headers, edel intake + carb. I want to go to a lower gear but would also like to have bigger axles ready for next summer. Should I just maybe go w 10 bolt and beef them up w chrome moly axlesand lower gear. Your 2 cents.
