The report documents the findings of an incremental cost, weight, and leadtime analysis developed from process cost and weight teardown of heavy truck ABS hardware from three manufacturers - Rockwell/WABCO, Midland-Grau and Bendix. Both truck tractor and trailer ABS configurations were studied including failure warning systems and several types of ABS tractor/trailer connectors. The scope of this study was confined to Class 7 and 8 trucks and tractors/trailers, which represent 72.4% of the total vehicles under consideration. A baseline tractor/trailer combination, an '18-wheeler' Navistar tractor pulling a Great Dane trailer, was used to determine cost and weight estimates of the three different ABS manufacturer's hardware and ABS configurations when fully installed on the vehicle. A supplementary analysis of Class 7 single unit trucks using Rockwell/WABCO hardware provided estimates for incremental cost and weight impacts for this class of vehicle. The significant findings of this study are: Tractor/trailer antilock braking system configurations examined in the study should result in price and weight increases no greater than $1700 and 100 pounds per vehicle combination; Single unit heavy truck ABS should result in price increases of $900 or less per vehicle; and The proposed effective dates for ABS installation for each vehicle type should permit adequate leadtime for implementation of heavy truck antilock braking systems as standard equipment.
