Shorter 4.625 gearing is intended to recover some of the low-speed response lost when a vehicle moves to larger tyres. This is a full gear-set purchase rather than an electronic correction, so axle specification and professional differential setup are central to the buying decision.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVehicles running larger-than-standard tyres\u003c\/li\u003e\n\u003cli\u003eBuilds where mechanical gearing is being matched to tyre diameter\u003c\/li\u003e\n\u003cli\u003eOwners planning front and rear differential work together\u003c\/li\u003e\n\u003cli\u003eInstallations handled by a differential specialist\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eMechanical Ratio Change Rather Than A Speedometer Adjustment\u003c\/h2\u003e\u003cp\u003eRecalibrating tyre size can correct displayed speed and shift information, but it does not change the torque multiplication inside the axle.
