Product Description

See Superlift's videoFor most 2WD and 4WD GM, Ford, Dodge and Toyota vehicles.

Virtually every vehicle manufactured since 1992 is equipped with an electronic speedometer that uses a sensor to read vehicle speed rather than a mechanical cable. This speed signal is a big factor in the overall performance equation. The speed sensor sends its signal to the Engine Control Module (ECM), the Power train Control Module, transmission, and if applicable, the anti-lock system "brain." When tire height and/or axle gearing is altered, these control units receive erroneous information. In all but the most extreme cases (really huge tires), an incorrectly calibrated vehicle will operate, but not at its peak. For example: if a vehicle is factory equipped with 28" tall tires and they are changed to 35s, a 20% change has occurred. Unless remedied, the various control systems will "think" that the vehicle is traveling 20% slower than it actually is. To make matters worse, newer computer-controlled vehicles have become extremely sensitive to changes in tire diameter and axle gear ratio. The reduction in performance can be difficult to gauge, but it is real. Plus, the number and degree of malfunctions increase as speed signal inaccuracy increases.

The TruSpeed addresses all speed signal-related problems; it doesn't just correct the speedometer. How? The TruSpeed module installs in-line with the factory electronic speed sensor and converts the wrong speed signal into the correct one for your vehicle's new tire and/or axle gear ratio combination. Because the signal is altered at its source, all speed-sensitive vehicle systems will receive the correct speed data, which restores all proper functions. The TruSpeed is available for most domestic and import vehicles equipped with an electronic speedometer.

Superlift TruSpeed Speed Sensor Calibrator Main Features:
  • Corrects speedometer / odometer readings, and the speed signal sent to the engine, Power train, and anti-lock brake control modules. Besides the obvious, these modules affect fuel delivery, engine timing, and automatic transmission shift points.
  • Eliminates speed signal related reductions in engine performance and fuel economy, as well as related changes in exhaust emissions
  • Infinite adjustability provides precise speed signal calibration within 1%
  • Two settings allow off-roaders that seasonally run different height tires to correct their speed signal by flipping a switch
  • Simple four-wire hookup Includes complete instructions and adjustment charts
  • Can be recalibrated infinitely for future tire size or gear ratio changes
  • Works on most vehicles equipped with an electronic speedometer

Great product purchased from a fabulous company. Purchase was easy and product arrived on time. Installation was straight-forwar-
d and initial calibration was on the money (I hd already calculated percentage error and used the "percentag-
e calabration&quo-
t; instructions included with unit). My speedo now agrees perfectly with my GPS. And to think my local dealer said it couldn't be done.

Great service from 4WS! On the TruSpeed both of the power and negative wires were too short. I had to lengthen both for my 2000 Tacoma. The other two wires that go to the speed sensor on the back of the transfer case only had a few inches to spare! Overall the kit seems pretty good.

Easy installation, about an hour start to finish. I Callibrated my speedo after installation with a GPS and then double checked with a Speed Radar, and my speedo seems to be dead on.

This has improved my shifting by 100% I had the whole job in 45 minutes that is inclueding calibrating (with a GPS) That is the easiest way I wound to do it. and this is the cheapest place to buy it Thank You for a great prouduct

Well satisfied, instruction were good, calibrated my speed to +/- two ten's of MPH using my GPS. I had to shut off my engine for my recalibrations to take place. Wires could be 6” longer.

Tru speed works great. One hitch though. The directions do not include how to connect it to RAMs with Rear Wheel ABS . So if you have a RWAL then it needs to be connected between the CAB and the PCM, to the white wire with the orange stripe.

The hardware works great. The instructions were a little off, but if you have done things like this before, it is pretty easy to install. Calibration can be tedious, especially if you want it very accurate. Ov-
erall, a great product.

Shipped quick all parts there with detailed instructions. Installed in about fifteen minutes and set the calibration according to the charts. I did a gear swap and larger tires both. Checked the speedometer with a garmin gps and was within 1/2 a mile an hour. Good product and thanks agian 4ws.

Ordered one Superlist TruSpeed Speedometer Calibrator. Order arrived within a few days (Fast!). Packaging was sufficient for protection of the item. The TruSpeed was harder to install than I thought, and thats because of my truck and the layout of the wires. Once I figured how to get to the hidden wire to splice, completed in no time. TruSpe-
ed works like a charm. Recalibrated my 35" BFG's and now set to GPS. Placed new 37" BFG KO's on, reset the TruSpeed to the second setting, now have two setting's. One for the 37" BFG and the other for the 35" BFG's. BTW, This site had the lowest pr
