TruSpeed  Finally, a speed sensor calibrator has arrived that addresses the needs of computer-controlled vehicles running larger or smaller than stock diameter tires. The Superlift TruSpeed calibrator installs in line with the speed sensor and recalibrates the signal sent to the computer. Because the signal is recalibrated at its source, speedometer reading, ABS functions, and transmission shift points are all corrected to work with the non-stock tire size.

• Precise speed signal recalibration; to within 1%

• Dual signal settings to make seasonal tire changes hassle free

• Simple four-wire installation

• The unit can be recalibrated infinitely for future tire and/or gear changes.

• Complete instructions and adjustment charts included; no guess work.

Our long-awaited module for recalibrating the factory Electronic Stability Program for Superlift-equipped WKs and XKs starts is shipping now. The Grand Cherokee and Commander were some of the first vehicles to include Jeep’s Electronic Stability Program (ESP). Creating a true performance lift system with ESP compatibility has been a stumbling block for most suspension manufacturers. Superlift relies on our exclusive Electronic Geometry Recalibration (EGR) module, produced by AEV, to provide the properly calibrated steering input signal to the factory ESP unit. The EGR module also allows for speedometer recalibration, desired when taller height tires and / or different axle gear ratios are installed. The module simply plugs into an existing wiring harness located beneath the dash. Use only with the Superlift / AEV Cherokee and Commander lift systems.
