P1011 INDYCAR SERIES GEARBOX
The 'P1011' Gearbox is Xtrac's third generation of IndyCar Transmission, continuing the line of
Quality, Performance and Reliability that are Xtrac's hallmarks. A completely new design of gearbox over its predecessor. This helps improve safety by reducing the inertia of the vehicle in a spin also allowing a large crash structure to be added to help absorb the energy from rear end impacts.
Drive is fed from the engine directly to the gearchange cluster and on to two pairs of drop gears, which in turn drive a hard cut Klingelnberg bevel set. In standard configuration the bevel drives a lightweight spool with integral output flanges and a differential is available for use on Road Courses. Gear changes are performed using Xtrac's, positive and reliable sequential gearchange mechanism.
Xtrac's legendary record for reliability and performance is built by products like this, which have won multiple Indy 500 victories, in fact every '500' since 2000.
