The Texas Speed 6.4L Hemi MDS Delete Kit supplies the parts needed to remove the factory Multi-Displacement System from a 6.4L Hemi and convert it to a conventional non-MDS camshaft and lifter configuration. The kit is built around an OEM 6.4L non-MDS camshaft that retains variable valve timing, paired with OE-style non-MDS lifters and retainers, so the engine keeps stock-style drivability without the cylinder deactivation hardware that is a common failure point.
Along with the cam and lifters, the kit includes left and right cylinder head gaskets, a head bolt kit, valve cover gaskets with spark plug tube seals, Mahle water pump and exhaust manifold gaskets, a timing cover seal and gasket set, a balancer bolt, a VVT cam bolt and MDS expansion plugs. Tuning is required after installation to disable MDS in the calibration. Texas Speed offers the TSP-TS-3000 programmer for supported applications through 2014 and the TSP-TS-3002 for 2015 and newer Dodge and Ram vehicles.

Ordering Options
One selection is required when ordering: choose the car kit or the truck kit to match the vehicle. Two optional tuner add-ons are also offered: the TSP DOD/MDS Delete Programmer (TSP-TS-3000) for supported 2005 to 2014 Dodge, Chrysler and Ram applications, or the TSP 2015+ Dodge/Ram MDS Delete Programmer (TSP-TS-3002) for 2015 and newer vehicles. Select None for either tuner if a tune is being handled separately.
Note: Tuning is required after installation. Because the engine is converted to a non-MDS camshaft and lifter configuration, MDS must be disabled in the calibration for proper operation.
Note: 2015 and newer vehicles require an unlocked PCM before tuning. With the TSP-TS-3002, Diablosport's cross-ship process supplies an unlocked PCM with a prepaid return label for the factory unit. 2018 and newer applications include a bypass module (trucks) or bypass harness (cars), and 2019 and newer vehicles must have the factory PCM read before the unlocked PCM is installed.
Note: Verify engine, model year, PCM and tuning compatibility before installation. Additional components or PCM services may be required depending on the vehicle year and configuration.

FAQ
What is included in the Texas Speed 6.4L Hemi MDS Delete Kit?
The kit includes an OEM 6.4L non-MDS camshaft with VVT, 16 OE-style non-MDS lifters with retainers, left and right head gaskets, a head bolt kit, valve cover gaskets with spark plug tube seals, a timing cover seal and gasket, Mahle water pump and exhaust manifold gaskets, a balancer bolt, a VVT cam bolt and MDS expansion plugs.
Should I order the car kit or the truck kit?
Choose the car kit for 6.4L Hemi cars such as the Challenger, Charger, Chrysler 300 and Jeep Grand Cherokee SRT, and the truck kit for 6.4L Ram trucks. The selection is made from the Car or Truck option when ordering.
Is tuning required after installing the 6.4L MDS delete kit?
Yes. The factory MDS system must be disabled in the calibration once the non-MDS cam and lifters are installed. Texas Speed offers the TSP-TS-3000 for supported applications through 2014 and the TSP-TS-3002 for 2015 and newer Dodge and Ram vehicles as optional add-ons.
What is different about tuning a 2015 or newer Hemi?
2015 and newer vehicles have a locked PCM that must be unlocked before tuning. With the TSP-TS-3002, Diablosport cross-ships an unlocked PCM with a prepaid return label for the factory unit. 2018+ applications include a bypass module or harness, and 2019+ vehicles need the factory PCM read before the replacement is installed.
Does this kit keep variable valve timing?
Yes. The camshaft in this kit is an OEM 6.4L non-MDS grind that retains VVT, so only the Multi-Displacement System is removed. The engine keeps stock-style performance and drivability.
Why delete MDS on a 6.4L Hemi?
MDS lifters and the cylinder deactivation system are a common failure point on Gen III Hemi engines. Converting to non-MDS lifters and a non-MDS camshaft removes that hardware and keeps the engine running on all eight cylinders at all times.
