3.55 is the sweet spot, almost zero effect on MPG's, yet substantially higher towing capacity. 3.55 all day long and twice on Sundays! Just curious your thoughts for guys who have either the 3.21 and 3.55 gears? Esp for the V6. Thx! Click to expand...

2021年10月13日 · 3.55 will keep the RPMs slightly higher at the same speed compared to the 3.31. So, not a lot of difference, maybe 200-300RPM. But, when travelling at speed with a load, that may be the difference between driving in 9th gear, and driving in 8th gear. The easiest way to think of it is, the higher the number, the quicker you will have torque to pull.

2024年2月8日 · the 3.15 will be better for daily stuff and fuel economy, but getting the 3.55 gives you more future options. ones like putting a Torsen diff (a better limited-slip diff than the standard clutch pack type) in it, changing the gears for 3.73 or 4.09 or stuff like that. the 3.55 also has better acceleration. attached is a chart i made a while ago ...

2020年10月16日 · I'd recommend going with the 3.55 ratio for slightly better performance when towing, and also for slightly better resale value, since odds are the next owner will probably tow more, and therefore prefer the 3.55 over the 3.31. Thanks.. Resale is something to consider. I found a dealers that still has two 2020 with 3.31's on the lot.

2017年9月16日 · Basically, the higher numbered gears (usually referred to as lower gears) allow the motor to turn more rpm's in the same gear, at the same speed, all other things being equal. That is the reason you want lower gears for towing, to allow the motor to run in a slightly higher, and therefore more powerful, rpm range.

2019年4月20日 · I've been looking at newer used trucks, 17+, and noticed a lot of them have 3.55. How big of a difference that will be? With the 6.7, you won't notice the difference unless you lift the truck and put huge tires on it.

According to the Destiny 2 update 3.55 patch notes, the latest update brings numerous fixes and improvements across activities, raids, dungeons, competitive modes, and weapon functionalities.

2021年2月19日 · F350, 3.31 vs. 3.55 rear axle ratio Looking at the tow ratings for the F350 (diesel, short bed, crew cab, 4x4), it seems that there is no difference between the 3.31 and 3.55 ratios. Obviously the 3.55 ratio may provide a little more oomph but with a planned max trailer weight of 15,000 lbs I guess it should not matter?

2019年5月23日 · My thinking is, the 3.55 should run at a higher rpm than the 3.21 at 1700 (in ECO), thus able to absorb the "bumps" in the road better. My logic is that any changes in a machine can cause more wear.

2024年5月11日 · When you’re considering performance upgrades for limited slip rear axles, understanding the distinction between 3.15 and 3.55 ratios can greatly impact your driving experience. The fundamental difference between these two lies in their gear ratios—a critical aspect that directly influences torque, acceleration, and fuel economy of your vehicle.
