The Texas Speed MDS Delete Kit is an a la carte package for removing the factory Multi-Displacement System from a 2009 and newer 5.7L or 6.4L Gen III Hemi. Instead of a fixed box of parts, the kit starts with four MDS delete expansion plugs and lets the buyer choose each supporting component, so parts already on hand are not paid for twice. It suits both a performance cam swap and a return to a stock-style non-MDS valvetrain.
Selections include MLS head gaskets, timing cover gasket and front crank seal, valve cover gaskets, water pump gasket, exhaust manifold gaskets, head bolts or studs, crankshaft balancer bolt, VVT cam bolt, hydraulic roller lifters and a factory-style non-MDS camshaft. Texas Speed requires a non-MDS camshaft for the delete, either the OE-style cam offered here or an aftermarket performance cam purchased separately, and ECU tuning after MDS is disabled. The Texas Speed 5.7L Low Lift Cam Kit and 6.4L 3-Bolt Cam Kit both require this kit.

FAQ
What is included in the Texas Speed MDS Delete Kit?
The base kit includes four TSP MDS delete expansion plugs. Head gaskets, head bolts or studs, timing cover gasket and seal, valve cover gaskets, water pump gasket, exhaust gaskets, crank bolt, VVT cam bolt, lifters and a non-MDS camshaft are each selected or declined when ordering.
Which Hemi engines does the MDS Delete Kit fit?
Texas Speed lists the kit for 2009 and newer 5.7L VVT and 6.4L Gen III Hemi engines in Dodge, Chrysler, Jeep and Ram vehicles. Texas Speed sells a separate cam kit for 2003 to 2008 5.7L and 2005 to 2010 6.1L non-VVT engines.
Do I have to buy a camshaft with the MDS delete?
A non-MDS camshaft is required to delete MDS. Choose the TSP OE-style 5.7L or 6.4L non-MDS cam in this kit for a stock-style result, or select Do Not Need and pair the kit with an aftermarket Texas Speed Hemi camshaft.
Is tuning required after an MDS delete?
Yes. Texas Speed states ECU tuning is required after disabling the factory MDS system so the engine runs on all eight cylinders without fault codes.
Which lifters should I choose for the MDS delete?
Texas Speed offers Mopar Hellcat lifters and trays, TSP Hellcat-style lifters and trays, or Johnson lifters and trays. All are non-MDS lifters; choose Do Not Need if suitable lifters are already on hand.
Does this kit work with the Texas Speed Hemi cam kits?
Yes. Texas Speed states that its 5.7L Hemi Low Lift Cam Kit and 6.4L Hemi 3-Bolt Cam Kit must be purchased with this MDS Delete Kit, since those cam kits do not include the delete components.
