These Chevy-specific kits are modeled around 2500HD/3500 platforms to address frame rail spacing, steering shaft angles, HVAC clearances, and downpipe pathing. Whether you’re building a dependable tow rig or a strong daily driver, DPS components help your Cummins deliver torque with predictable temps and service access.
Support varies by model year and package. Typical targets include Silverado/Sierra 2500HD & 3500 across LB7, LLY, LBZ, LMM, LML, and L5P eras. Verify transmission choice, accessory layout, intercooler path, downpipe clearance, and oil routing on the product page for your year.
Application-specific turbocharger option, exhaust manifold or adapter as listed, hot-side and charge-air plumbing, oil feed/return solutions, clamps/couplers, brackets, heat shielding, and hardware. See each kit for exact contents and actuator/sensor provisions.

A Chummins conversion installs a Cummins diesel into a Chevy 2500HD/3500 chassis. The goal is Cummins torque and durability with Chevy ride and packaging.
Yes. With correct turbo sizing and plumbing, you can keep good street manners, quick response in traffic, and stable temperatures on long grades.
Match size to load, elevation, gearing, and tire diameter. Towing builds prefer earlier spool; performance builds may select larger compressors with freer turbine housings and appropriate fueling.
Many swaps benefit from calibration updates to optimize fueling and shift strategy. If injectors or pumps are upgraded, tuning is recommended.
Confirm transmission adapter, motor mounts, intercooler piping route, downpipe path, and oil feed/return provisions. Gather fresh gaskets, fluids, quality clamps, and high-temp boots.
