Getting fast and accurate information relating to shaft RPM is of critical importance to drag racers with on-board computers. That’s why noted driveline products manufacturer Mark Williams Enterprises has developed this new solid-state computer pickup for 9" Ford rears that is compatible with RacePak and other data logging systems.

M-W’s innovative new design features a lightweight steel trigger ring and solid-state electronic pickup, which delivers 12 pulses-per-revolution instead of the one through four pulses available through magnetic-type pickups. This new trigger is more accurate than the older magnetic types, and very resistant to vibration.

In addition to the ring and pickup (which features a male 3-socket connector for the RacePak, etc.), the M-W shaft RPM sensor indludes a pickup mounting bracket and a pinion seal (the seal rides on the trigger ring, rather than the yoke or coupler). Assemblies are currently available for 9" Ford rear ends with 28, 32 or 35-spline pinions. Other applications are slated to follow.

Mark Williams Enterprises is celebrating its 45th year in business, and is best known for its line of forged steel axles, driveshafts and disc brake systems.
