[QUOTE="Dreman, post: 837885, member: 61303"] Try smaller tires for your runs. A smaller diameter tire is an easy way to reduce the effective rear axle ratio. Assuming your original tires are 255-70R16s, going to a 255-60R16 would make the truck feel like it had a 4.40 rear axle ratio with the original tires. Going to 50 series tires would make it the same as a 4.74 rear axle ratio. Easier and cheaper than an axle change. And get some steel spare tire rims for your drag tires. Although I'm not sure about the Sport Trac, they are usually lighter than the cast aluminum wheels. [/QUOTE]
