2007 2WD Chevy Silverado 1500 - Second HelpingPosted in Features on September 23, 2013 0) (
Aaron Werner acquired this '07 Chevy a good number of years ago. It ran around stock until he decided he wanted improved performance in the dirt. That's when he went to brothers Jimmy Adams and Chad Lien at Xcentrix Motorsports and Fabrication (XMF) in Mesa, Arizona, to see what hardware they could bestow on a factory stock Silverado.
The brothers sawed off the factory front shock mounts and built tubular shock towers in their place, along with a crossover support that hovers above the engine and ties the towers together. Tossing the factory shocks, they replaced them with a set of 2.5 King 8-inch stroke coilovers. The improvement was substantial and the truck handled desert two-track and dirt far better.
But, as with most truck addictions, this one took hold of Aaron and he wanted more performance from the Chevy. A call was again made to XMF and Aaron expressed his interest in a second helping of their fabrication. This time the call was for a full long-travel front suspension and fiberglass treatment on both ends of the truck.
The brothers went to work fabricating and installing a 16-inch travel front setup and swapped the King shocks up to 10-inch travel versions. Hydraulic bumps help stop the upward movement at full stuff and heavy-duty steering upgrades were applied as well.
Tire size was upped to 37-inch meats and the rear axle re-geared to a more torque-friendly 4.56:1 gear ratio. At this point, the rear suspension remains stock. But, bedsides are in place and the 37s are itching for more travel into those bulged fiberglass skins. It's only a matter of time until Aaron moves from his second helping of truck upgrades to a sweet dessert portion of long-travel rear-axle improvements.
