A/C Line Relocation Kit for 6.7 Cummins 2010-2018 | Compound Turbo and Swap Kit Clearance
The Diesel Power Source® A/C Line Relocation Kit for 2010-2018 Dodge Ram 6.7L Cummins trucks replaces the factory A/C lines and repositions them to create clearance for compound turbo kits, 2nd gen swap kits, 3rd gen swap kits, and other aftermarket turbo configurations that require additional space on the exhaust side of the engine. The factory A/C lines run directly through the area where large-frame atmospheric turbos and compound piping need to be routed, making this kit a required component for most aftermarket turbo installations on 2010-2018 trucks.
This kit replaces the restrictive OEM A/C lines with new lines that route around the turbo system while maintaining full air conditioning function. All fittings, lines, and hardware needed for a complete installation are included.
Why This Kit Is Needed
On 2010-2018 6.7 Cummins trucks, the factory A/C lines route across the top of the engine in a path that directly conflicts with aftermarket turbo systems. Compound turbo kits use a large atmospheric turbo (S475 or S480) that physically occupies the space where the factory A/C lines run. Without relocating these lines, the compound system or swap kit cannot be installed. Attempting to bend or modify the factory lines risks damaging the A/C system and creating refrigerant leaks.
This relocation kit provides a clean, purpose-built solution that maintains full A/C function while creating the clearance needed for aftermarket turbo configurations. It is the same solution DPS recommends for all 2010-2018 compound turbo and swap kit installations.
What's Included
- Complete replacement A/C line set (rerouted for turbo clearance)
- All aluminum fittings
- All hardware needed for installation
*Installation Warning
Important: Fittings are made from aluminum, which is a soft metal. Always begin threading fittings by hand to verify correct alignment before tightening. Torque fittings to a maximum of 100 inch-pounds only. Do not overtighten. Cross-threading or damage to threads caused by improper installation is not covered by warranty.
Key Features
- Creates Turbo Clearance — Repositions factory A/C lines to clear compound turbo kits, 2nd gen swap kits, 3rd gen swap kits, and other aftermarket turbo configurations
- Maintains Full A/C Function — Your air conditioning continues to work normally after installation
- Complete Kit — All replacement lines, fittings, and hardware included
- Purpose-Built for 2010-2018 — Engineered specifically for the 6.7 Cummins engine bay layout on these model years
- Required for Most Aftermarket Turbo Setups — Factory A/C lines conflict with large-frame turbo and compound piping on 2010-2018 trucks
Which Turbo Setups Need This Kit?
This A/C line relocation kit is recommended or required for the following DPS products on 2010-2018 trucks:
- Complete Compound Turbo Kit for 6.7 Cummins (2007.5-2018)
- 3rd Gen Swap Kit for 6.7 Cummins (2007.5-2018)
- Ball Bearing 3rd Gen Swap Kit (2007.5-2018)
- Any aftermarket turbo configuration that uses a large-frame turbo in the factory turbo area on 2010-2018 trucks
2007.5-2009 trucks: The engine bay layout is slightly different on these earlier model years and may not require A/C line relocation depending on the turbo configuration. Contact DPS to confirm.

Frequently Asked Questions
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.
No. This kit is designed specifically for 2010-2018 Ram 6.7 Cummins trucks. The 2007.5-2009 engine bay layout is slightly different and may not require A/C line relocation depending on your turbo configuration. Contact DPS to confirm.
This is not recommended. The factory A/C lines are rigid and bending them risks cracking the lines, damaging fittings, and creating refrigerant leaks. This relocation kit provides a purpose-built solution that maintains proper A/C function without risking damage to the system.

Not quite right for 10-12 trucks
Fitting at compressor does not line up correctly and are on top of each other. Could be higher quality hose and fittings. Some fittings are stepped unlike OEM.
