Premium Differential Covers & Thermal Protection

Excessive heat ruins gear lubrication during heavy-duty towing. Protect your investment with upgraded aluminum diff covers. We feature innovative solutions like the patented Banks Power Ram-Air Differential Cover Kit. This kit utilizes multi-directional cooling scoops to lower fluid temperatures significantly better than flat-back styles. You can also browse rugged cast-aluminum options such as the ATS Protector Differential Cover line. These covers increase fluid capacity, feature built-in heat sinks, and integrate magnetic drain plugs for simplified servicing.
