What is best gear ratio for 4×4?

between 4.10 and 5.38
The powerband of your engine and the tire size determines the optimum ring-and-pinion ratio for your 4×4, but the majority of street-driveable off-road vehicles will fall between 4.10 and 5.38. If your engine has a bit more low-end grunt, then you can stay on the higher side (4.10s).

What axle ratio is best for off roading?

Under 50 Crawl Ratio – Most factory setups fall here. 50-60s Crawl Ratio – Backroads and light trail use. 80s Crawl Ratio – Intermediate trail use. 110-130s Crawl Ratio – Ideal for crawling, it allows taking obstacles at a slow, controlled speed without riding the brakes or applying constant throttle to avoid stalling.

What gears are good for off roading?

Six Examples of Must-Have off Road Gear

  • A heavy-duty jack. If you have ever tried, then you know what a total pain it is to change a tire once you are away from cement-paved roads.
  • Multi-purpose fire extinguisher.
  • Flashlight and portable lighting.
  • Portable air compressor.
  • Extraction toolkit.
  • First-aid kit.

What gears do I need for 37 tires?

Upgrading to 37-inch tires would calculate to about a 16 percent increase in tire diameter. Increasing the 4.10 axle ratio by 16 percent would dictate the need of a 4.75 axle ratio to match the 37-inch tires.

What is a good crawl speed?

An ideal crawl ratio for general-use 4x4s is typically in the 50:1 range. Those who tackle more difficult terrain will strive to obtain at least a 100:1 ratio. Crawl speed is another bit of terminology that can be helpful to know.

Do front and rear diff gears have to match?

If you plan on using 4wd then yes you must. If you plan on NEVER using 4wd then no.

Do front and rear axle gear ratios have to match?

As long as there’s less than a 1% difference between the ratios, they’re considered “close enough”. If your front axle only has 4.11 gears (37 ring gear teeth and 9 pinion teeth) but your rear axle has 4.09 gears (45 ring gear teeth and 11 pinion teeth) the ratios don’t match exactly.

What is the gear ratio on a 4×4 truck?

Differential Gear Ratio The gear ratio most interesting to 4×4 truck owners is the ratio between the driveshaft and axles – the differential gear ratio or axle gear ratio. It is controlled by the number of teeth on the ring vs. the pinion. A ratio of 4.56 means that as the axle turns one whole circle the driveshaft turns 4.56 circles.

What kind of gear does a 4×4 drive shaft have?

This is the Rear Heavy-Duty Driveshaft Assembly, left or right, with screw pin that comes fully assembled for the Slash 4X4 or Stampede 4X4 monster trucks. This item replaces the TRA6852. This is the Traxxas Spur Gear 52-Tooth 0.8 metric pitch for the Slash and Stampede 4×4 center differential. It is compatible with 32-pitch.

What kind of gear does a Traxxas 4×4 have?

This is the Rear Differential Ring and Pinion Gear set for the Traxxas Slash and Stampede 4×4. This is a 16-tooth, 32-pitch heavy duty hardened steel pinion gear for several Traxxas vehicles. This is the gear which is attached directly to the motor.

Why is the correct axle gear ratio important?

The correct axle gear ratio is important for drivability and economy. When you increase the tire size without changing the gear ratio you increase fuel consumption and you can not drive at the low speeds needed for the off roads. The most simple formula for the correct gear ratio is this:
