2021-2025 Jeep/RAM/Dodge Camshaft Rocker Arm Advisory

This manufacturer communication, identified as TSB 9100622 and issued on July 3, 2025, provides an important clarification for technicians and owners regarding engine component replacement. Specifically, it addresses the ordering of rocker arms when performing a camshaft replacement on various 2021-2025 Jeep, RAM, and Dodge models. This advisory aims to prevent the unnecessary purchase of parts that are already supplied within a larger assembly, streamlining the repair process and potentially reducing costs for a Jeep Wrangler camshaft rocker arm service. Such communications are vital for ensuring accurate repairs and efficient parts management within the service network.

Understanding Camshafts and Rocker Arms

To understand the significance of this advisory, it helps to know the role of these engine components. The camshaft is a rotating shaft that opens and closes the engine's intake and exhaust valves. It has lobes (cams) that push against rocker arms (also known as roller-finger followers). These rocker arms then transfer the motion to the valves, allowing fuel and air into the cylinders and exhaust gases out. Both components are critical for the engine's timing and overall performance.

Important Advisory: Avoid Unnecessary Parts Ordering

The core message of this communication is a crucial warning for anyone involved in camshaft replacement. The document explicitly states: "When replacing a camshaft and parts kit (P/N 68661146xx and/or 68661147xx), it is NOT necessary to order the roller-finger followers (rocker arms) separately, as these are included in the camshaft parts kit." This directive is designed to prevent common ordering errors and ensure that repair facilities are not incurring extra costs or delays by purchasing redundant parts. Ignoring this advisory would lead to duplicate inventory and potentially higher repair bills for customers.

Affected Components and Part Numbers

This advisory pertains to specific engine components and their associated part numbers:

• Rocker Arm: Identified by part number 05047896A$. These are the individual components that transfer motion from the camshaft to the engine valves.
• Camshaft and Parts Kits: These comprehensive kits are referenced by part numbers 68661146xx and 68661147xx. The 'xx' in these part numbers typically serves as a placeholder for additional digits that denote specific variations, such as engine type, production batch, or minor design revisions. These kits are designed to be all-inclusive, providing all necessary components for a complete camshaft replacement, including the roller-finger followers (rocker arms).

What This Means for Owners

For owners of affected 2021-2025 Jeep, RAM, and Dodge vehicles, this communication is valuable information. If your vehicle requires a camshaft replacement, it's beneficial to be aware of this advisory. You can discuss TSB 9100622 with your service technician to ensure they are informed that the rocker arms are indeed included in the camshaft kit. This proactive approach can help prevent potential overcharges for parts that are not needed. Whether you own a Jeep Wrangler, RAM 1500, or Dodge Durango, understanding this detail about the Jeep Wrangler camshaft rocker arm replacement process can lead to a more efficient and cost-effective repair. Always ask for a detailed breakdown of parts and labor before authorizing any major engine work.
