Gear Ratio Calculator: Crawl Ratio and RPM

Plan a regear or a tire upgrade with the whole drivetrain in view. Set up your current 4X4 and the build you are planning side by side, and the calculator shows the crawl ratio, the engine RPM at cruising speed, the speed in every gear and the axle ratio that keeps the feel you have now. Start from a vehicle in the list or enter your own transmission, transfer case, underdrive, axle and portal ratios.

How to use the calculator

Current setup: pick your vehicle to fill in the transmission, transfer case, a common factory axle ratio and tire size, then correct the axle ratio and tire to match yours. Every ratio box can be edited, and the + and − buttons add or remove gears.
Planned setup: it starts as a copy of the current one (the Copy button resets it). Change the tire size, the axle ratio or anything else you plan to swap.
Read the comparison: the table shows what changes, the regear box lists the closest axle ratios to your current feel (tap one to try it), and the chart plots engine RPM against road speed in every gear.
Fine-tune: set the cruise speed, redline and table columns, switch to km/h, and use Copy link to save or share the exact setup.

The math behind it

Every gear in the drivetrain multiplies. The overall ratio in any gear is the transmission gear × the transfer case range × the underdrive (if fitted) × the axle ratio × the portal ratio (if fitted). The crawl ratio is the overall ratio in first gear and the lowest range. A Jeep Wrangler JL Rubicon with the 8-speed automatic has a 4.714 first gear, a 4.00 Rock-Trac low range and 4.10 axles: 4.714 × 4.00 × 4.10 = 77.3:1, so the tires turn once for every 77.3 turns of the crankshaft.

Road speed comes from the tire height: mph = RPM × tire height ÷ (overall ratio × 336). The constant 336 converts inches per minute to miles per hour (63,360 inches in a mile ÷ 60 minutes ÷ π). The same formula solved for RPM gives the engine speed at a road speed. Older automatics whose torque converter never locks slip a few percent at cruise; the checkbox for them uses 355 in place of 336, which adds about 5 percent to the RPM figures.

Factory crawl ratios for comparison

Calculated from each vehicle’s first gear, low range and axle ratio:

Ford Bronco Sasquatch, 7-speed manual (6.588 × 3.06 × 4.70): 94.7:1
Jeep Wrangler JL Rubicon, 6-speed manual (5.13 × 4.00 × 4.10): 84.1:1
Jeep Wrangler JL Rubicon, 8-speed automatic: 77.3:1
Jeep Wrangler JK Rubicon, 6-speed manual (4.46 × 4.00 × 4.10): 73.1:1
Ford Bronco Sasquatch, 10-speed automatic (4.696 × 3.06 × 4.70): 67.5:1
Jeep Wrangler JK Rubicon, 5-speed automatic (3.59 × 4.00 × 4.10): 58.9:1
Jeep Wrangler TJ Rubicon, 4-speed automatic (2.84 × 4.00 × 4.10): 46.6:1
Jeep Wrangler JL Sport, 8-speed automatic with 3.45 axles (4.714 × 2.72 × 3.45): 44.2:1
Toyota Tacoma 2016-2023, 6-speed automatic (3.60 × 2.57 × 3.91): 36.2:1

A taller tire lowers the effective crawl ratio in proportion to its height, which is why regearing usually comes with a tire upgrade. Low range kits (4:1 conversions for the NP231 and Dana 300), underdrives and doublers raise it without touching the axles.

Regear chart: axle ratio for bigger tires

The ratio that restores factory gearing after a tire change is the stock ratio × new tire height ÷ old tire height. Each cell shows the closest common ring and pinion ratio in bold and the exact figure in parentheses. Going a step above the exact figure gives more pull and higher cruise RPM; a step below gives the opposite.

Before you regear

Both axles must match. On a 4X4 the front and rear ratios have to be the same, or the drivetrain binds in four-wheel drive.
Ratios depend on the axle and carrier. Each axle model is made in its own set of ratios, and many carriers change between a lower and a higher series at a set ratio (the carrier break), so a deeper gear can also mean a different carrier or locker.
Plan the installation. A new ring and pinion needs new bearings, seals, shims and a crush sleeve or solid spacer, which come together in an installation kit, followed by a break-in period.
Recalibrate afterward. New tires and gears change the speedometer reading; the speedometer calculator shows how far off it is, and a speedometer calibrator sets the new size on late-model vehicles.

Shop ring and pinion gears, Dana 44 ring and pinions and transfer case parts. For more on axles, read Dana 30 vs Dana 44 vs Dana 60 and Ford 9-inch vs Ford 8.8, and use the tire size calculator to convert metric and flotation sizes.
