*The zRack S+ comes with a sensor. At this time the zRack S+ can not be purchased without a sensor. For a Zedaro rack without a sensor check out the zRack here*
Uncompromising by design, the zRack has been optimized over 5 years, with the support and feedback of many top student teams to be lightest and tightest (backlash-free), steering rack available.
Many teams asked for a position sensor for their zRack. We've seen and tested several bolt-on solutions but were never satisfied with the size, weight or precision compromise.
The new zRack Sensor integrates the best steering position sensor package available into a sleek new housing design that maintains all the performance, light-weight and reliability of the original zRack.
The new zRack Sensor adds:
- Fully enclosed and protected in an ultra low-profile housing the sensor is also fully sealed to IP67 against dust/water ingress.
- Solid state sensor provides accurate and reliable 360 degree steering position data. Non-contacting Hall Effects design can never wear or jamb with use.
- DC 5V input and 0-5V output compatible with all data acquisition systems.
Zedaro makes three sizes:
zRack S+ 262
zRack S+ 358
zRack S+ 442
The model numbers represent the eye span distance from tie rod mounting point to tie rod mounting point.

Question: What all does the zRack come with?
Answer: Included with the purchase of the zRack S+:
Question: Which way does the rack have to be mounted? With the pinion above or below the rack?
Answer: The zRack can be mounted either way. It makes no difference to the performance or longevity of the rack. Keep in mind that front steer cars (Meaning the tie rod connection to the upright is in front of the axis of the wheel) the pinion has to be ran under the rack. For rear steer cars (Meaning the tie rod connection to the upright is behind the axis of the wheel) the pinion has to be ran on top of the rack. If you do not follow these guidelines, your car will turn left when you turn the steering wheel to the right, and vice versa.
Question: What sizes of rack do you offer?
Answer: Currently the shown sizes above are the only three available. The size of the racks are measured by the clevis eye to eye length. The only differences between the three are the eye to eye length and the mounting span of the rack. The ratio and travel are the same.
Question: Can I get a custom size made?
Answer: There are limited customization possibilities at this time. It is possible to get a custom eye to eye, but it will cost up to $600 extra. At this time you can not get a custom ratio or longer travel.
Question: What material is the rack and pinion made of?
Answer: The rack and pinion of the current version are made of aluminum (previously titanium). The Zedaro designed tooth profile and special coatings significantly reduce the stress in the teeth, allowing the rack and pinion to be manufactured out of aluminium. Several years of dynamic and static testing have proven the strength of the teeth.
