We used this Laycock overdrive in our Class 7  off-road truck to get a competitive edge on our fellow racers.  With this overdrive we could leave the transmission in third gear and when coming out of a corner at full throttle hit the button and the overdrive would give me a nice gear in-between.  Also, in our line of racing; half the time the truck is airborne anywhere from one to six feet and the overdrive never skipped a beat, even under these harsh conditions. ~KC Keller ~
