Learn your modification options for the most modern and
exciting Jeeps!

Going back to World War II, Jeeps have had a special
place in America’s heart. The utility vehicle that helped win
the war transitioned into the civilian Jeep, or CJ, and the
Jeep brand has had several owners over the years. While still
remaining wildly popular, it has evolved. The Wrangler version
of the Jeep was transformed with the release of the JK for the
2007 model year. With a more practical 4-door version, this
Wrangler became a popular vehicle for year-round use, which
appealed to off-roaders as well as soccer moms. For the 2017
model year, Jeep seriously upgraded the Wrangler, which is
now dubbed the JL, and added an exciting new model, the
Gladiator, or JT, which is essentially a pickup version of the
Wrangler.

In Jeep Wrangler JL and Gladiator JT: Performance Modifications,
Jeep experts Don Alexander and Quinn Thomas
introduce you to these new models and walk you through the
capabilities and options for all of the trim levels. Then, they
examine how to make these things better, system by system.
Suspension, steering, and brakes are covered, as they are
the heart of any off-road rig. Also examined are modification
options for axles, driveshafts, and differentials as well as
bumpers, armor, and protection. Of course, off-roaders need
a quality winch, recovery gear, and upgraded electrics, so options
are explored here as well. Wheels and tires are also very
important for those leaving paved roads, and upgrade options
for all of the trim levels and lift levels are covered thoroughly.
Whether you want to build a JL or JT to be a serious rock
crawler or simply look like you are going off-road, all of your
options are thoroughly explained in this book. Add a copy to
your Jeep reference library today.
