Common Repair Parts
- Steering System - Upgrade the steering system by eliminating steering wander and “death wobble”, which vibrates the steering wheel. These 2 issues can be addressed by an upgraded track bar from BDS-Suspension, BD-power, and ReadyLift as well as a Steering box stabilizer from BD-power, ReadyLift & Synergy.
- Lift Pump - Your truck's stock lift pump is barely sufficient, and it will harm the CP3 injection pump if it fails. Use an aftermarket lift pump from FASS or AirDog to improve fuel flow and increase your fuel system's dependability.
- Exhaust Manifold - It is well known that the expansion and contraction caused by exhaust heat can cause the factory exhaust manifold to crack. The expansion joints in the BD-Power, ATS, and AFE manifolds will prevent cracking.
Popular Upgrades
- Cold Air Kit - By making it easier for the engine to breathe, an intake system will boost its power and efficiency. XDP provides an array of leading manufacturers, including S&B Filters, AFE, K&N, Volant, and many more.
- Tuner - Use the Edge Products, Superchips, and Banks Power programmers and modules to boost horsepower and torque while improving throttle response and efficiency.
- Exhaust - Enhance your exhaust system with a 4" or 5" system from MBRP, Magnaflow, AFE, Diamond Eye, and other manufacturers. These systems come in stainless steel or aluminized steel.
Popular Accessories
- Tonneau Cover - A truck bed cover or tonneau cover can provide much-needed protection for the items in your pickup bed. This protects your valuable cargo from the elements by protecting it from rain, snow, and UV rays in addition to offering a layer of security and privacy. Choose from leading brands like Access, Bestop, BAK Industries, and others to find the bed cover you need.
- Floor Liners / Floor Mats - For interior protection and to help preserve the vehicle's value, choose premium truck floor liners from WeatherTech and Husky Liners.
- Running Boards / Nerf Bars - You can get in and out of your truck more easily using running boards from manufacturers like AMP Research, N-Fab, Gen-Y, and others.
