Welcome to the Quiet Zone
Click on the Article to the right to read the Street Rodder magazine article
from September 2019 about John’s Industries’ Quiet Zone.
John’s Industries, the leader in 9” rear development and manufacturing, has
done it again. By working with US Gear and their new STEALTH SERIES of
high performance ring and pinion gears for the Ford 9”, John’s Industries
has been able to create one of the quietest 9” rears available for the
US Gear’s newest STEALTH Series gears utilize the most advanced gear
cutting technology, known as face hobbing. It’s a revolutionary new gear
cutting method that creates a continuous and more consistent cut on all
teeth of the ring and pinion at the same time. This maximizes tooth
contacts giving a wider pattern for an easier set up. The result is whisper
quiet, cutting edge performance.
US Gear is launching its new Ford 9” STEALTH Series gear, manufactured to
fit one of the most popular axles in the performance industry. They set out
to develop the next generation of 9” gears starting with a brand new design
and utilizing the best manufacturing processes. The gear setup is more
consistent, and most importantly, the new gears are much quieter than
standard gears. This collaboration is a breakthrough in rear end noise
reduction which has a plagued the performance industry for decades. CALL
