Vehicle Fitment

Fits 2002-2005 Dodge Ram 1500 Laramie, SLT, and ST models.

Maintain proper suspension geometry and ride quality on your leveled truck with Zone Offroad shock extension brackets. These relocation brackets are specifically engineered for 2002-2005 Dodge Ram 1500 pickups equipped with 2-inch leveling kits. By moving the lower shock mounting point higher on the control arm, these extensions prevent factory shocks from topping out, ensuring full droop travel and protecting internal shock valving during suspension cycling.

Constructed from heavy-duty steel and finished in a durable textured black powdercoat, these brackets are built to withstand off-road use and environmental corrosion. The simple bolt-on design installs directly to the lower control arm, allowing you to retain your factory shocks while benefiting from the increased stance of a leveling kit.

• Allows the use of factory shocks with 2-inch leveling kits
• Relocates lower shock mount to restore full droop and suspension travel
• Heavy-duty steel construction for maximum durability
• Textured black powdercoat finish for long-lasting corrosion resistance
• Simple bolt-on installation to factory mounting points
• Manufacturer Part Number: ZOND5201

Fits select 2011-2019 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD. These Zone Offroad front shock extension spacers are engineered to solve the common issue of restricted suspension travel after installing a 2-inch torsion bar key leveling kit.

When the front end is leveled using aftermarket keys, the factory shock absorbers often become the limiting factor in suspension droop. These spacers install directly onto the upper factory shock studs, effectively extending the shock's reach and restoring the full range of motion. This allows you to retain your original equipment shocks while ensuring the suspension can cycle properly without topping out the shock internals.

• Allows for full suspension droop travel with 2-inch torsion bar keys installed
• Mounts to upper factory shock studs for a straightforward installation
• Cost-effective alternative to purchasing longer aftermarket shocks
• Maintains factory ride quality by keeping shocks within their intended operating range
• Manufacturer Part Number: ZONC5202
