A/C Line Relocation Kit for 10-18 Dodge 6.7 Cummins

On 2010–2018 6.7L Cummins trucks, the factory A/C refrigerant lines run through the engine bay in a path that directly conflicts with where compound turbo piping, 3rd gen swap components, and large-frame aftermarket turbos need to be positioned. The factory lines cannot simply be moved out of the way — they are rigid and sized for a fixed route. This kit replaces them with new lines routed to clear the turbo system, allowing a clean installation without cutting, modifying, or damaging the factory A/C components.

This kit is designed for 2010–2018 Dodge Ram 2500 and 3500 trucks with the 6.7L Cummins engine. It does not fit 2007.5–2009 trucks, which have different factory A/C line routing that does not conflict with most turbo installations. If you have a 2007.5–2009 truck, confirm whether your specific compound or swap kit requires A/C line relocation before ordering.

On most 2010–2018 builds running a compound turbo kit or 3rd gen swap kit, yes. The compound kit listing notes it as an optional add-on for 2010–2018 trucks, but in practice the factory A/C line conflict affects the large majority of these builds. If you are unsure whether your specific truck and kit combination requires it, contact the Diesel Power Source® team with your model year and the kit you are installing before ordering.

Yes. This kit reroutes the A/C refrigerant lines to a new position that clears the turbo system while maintaining the same connections at the compressor and condenser. The A/C refrigerant circuit remains complete and functional. Cooling capacity and compressor operation are not affected — only the physical path of the lines changes. The A/C system will need to be evacuated and recharged after installation since the refrigerant lines are opened during the swap. Plan for this step as part of the build.

The fittings in this kit are machined from aluminum, which is a soft metal that requires careful handling during installation. Always begin threading every fitting by hand with correct straight alignment before applying any tool torque — aluminum cross-threads easily if a fitting is started at even a slight angle. Tighten only after confirming correct alignment, and torque to a maximum of 100 inch-pounds. Do not exceed this torque. Cross-threading or thread damage is not covered under warranty, and individual fittings are not sold separately — the complete kit must be repurchased if fittings are damaged during installation.

No — these are two completely different products that address different systems. The A/C line relocation kit replaces the factory air conditioning refrigerant lines to create clearance for aftermarket turbo components. The coolant reroute kit eliminates the failure-prone plastic coolant riser pipe and relocates the coolant tank on 2013–2018 deleted trucks. The two kits address different systems and different problems. On a 2013–2018 compound or swap build, both kits are typically needed together — the A/C kit handles refrigerant line clearance and the coolant kit handles the EGR riser and coolant tank relocation.

Yes. The A/C line routing conflict on 2010–2018 trucks affects both automatic and manual transmission models. The kit is designed around the 6.7L engine bay geometry and is compatible with both transmission options. If you have any specific clearance concerns related to your transmission or other underhood modifications, confirm with the Diesel Power Source® team before ordering.
