The 2014 Silverado Z71 returns as a unique model with 46mm monotube Rancho shocks – with fade-resistant design for more consistent performance – front tow hooks, a transfer case shield on 4WD models and 17-in. wheels. Unique 18-in. and 20-in. wheels with all-terrain tires are also available.
Hill descent control and GM’s exclusive automatic locking rear differential (available on other Silverado models) are also part of the Z71 package, providing maximum traction. Hill descent control is engaged by the driver and uses the anti-lock braking system to enable a consistent, controlled descent in rough terrain.
The automatic locking rear differential reacts in milliseconds in low-traction situations to improve safety and confidence on slick surfaces. Without driver input, the rear differential locks when a wheel-speed difference of 100 rpm or more is detected between the left and right wheels, providing instant traction for confident driving. In normal driving conditions, the differential functions as a conventional light-bias limited-slip axle.
