DHD 115-510 Dirty Alli-Locker 5-Speed Torque Converter Lockup Switch

The DHD Dirty Alli-Locker torque converter lockup switch was designed to be an exact fix for the ever long pursuit of true lockup controller that will work 100% of the time. After countless troubles with different aftermarket kits built by other vendors that were unreliable, DHD set to make the best lock up switch on the market. When you’re in a competition event, and a win is needed to move onto the next round, you can’t rely on a lockup box that only works when it wants to. The DHD Dirty Alli-Locker torque converter lockup switch won’t leave you second guessing if your Allison torque converter is fully locked up or not. DHD built a simple kit that overrided the TCM and allows full manual control of the Allison torque converter clutch at any time.

There are two modes, manual and automatic. Automatic mode is required for daily driving, but in the event that you want to immediately lock or unlock the converter, you can do so, at the flip of an easy to access switch. Manual mode will give user control, which is great for sled pulling or drag racing events. There isn't any need for boxes or interceptor modules that need to be mounted under the hood or on firewall.

Installation is a breeze with a simple wire harness that will need to be routed and interfaced with the TCM. After that, a switch is provided that you can mount in dash with factory hardware.

Note 1: This is an off-road/competition use ONLY product. It was solely designed for closed course drag racing or sled pulling events.

Note 2: Always remember to flip the toggles switches back to stock mode when not in use. We recommend having the locker active only during the immediate demand for lockup. Driving with the switches demanding lockup may cause erratic shifting, check engine lights or limp mode events.

Note 3: This product is offered with a direct "factory" mounting box that will work on all 2001-2007 Classic series Silverado & Sierra pickups. Or if you prefer, we also offer a universal box that you can mount anywhere in the cab. Make sure to select the proper drop-down upon checkout for your mounting preference.

Note:  We have not confirmed proper operation of the alli-locker on 2016 LML and 2017+ L5P trucks. Changes to the Allison TCM logic may limit the boxes effectiveness or cause erroneous codes. Additional TCM tuning may be required to limit TCM controlled converter lockup. DHD Recommends only editing these functions on Off Road Vehicles.

DHD's high flow manifold bundle increases exhaust air flow over 55% without any port modifications. Additional gains can be found in port matching and port blending. Our manifolds are cast from the same high Silca Iron that's become standard in the high flow manifold market. Included in the high flow bundle are our .120" wall thickness 304 stainless steel up pipes, featuring sleeved bellows and double welded pipe/flange connections.

Our manifolds swept back tapered inner diameter port design will accelerate exhaust gases to the turbine, lowering EGTS and making it easier for the turbo to spool quickly. 

Features / Benefits:

• Reduced Back pressure
• Improve Fuel Economy
• Lower EGT's and drive pressure
• Quicker turbo spool up
• 1/8NPT Bungs in each manifold for EGT or Drive Pressure Sensor

Bundle Includes:

• Right and Left Cast Manifolds
• Right and Left .120" Wall Stainless Up Pipes
• 16 4340 Chromoly M10 12pt Manifold Bolts (Not cheap socket cap screws)
• 2x 1/8NPT Port Plugs
• MLS Stainless Up Pipe Gasket Set (4 gaskets)
• MLS Stainless Manifold Gasket set (2 gaskets)
• 12 12.9 M10 12pt Up Pipe Bolts

Notes:

• The passenger side up pipe is D shaped to allow for use with most aftermarket downpipes. However, slight modifications may need to be made to get the best fit depending on downpipe brand.
• There is no EGR riser on the passenger side up-pipe. This kit is not a direct replacement for trucks equipped with EGR and should only be installed on pre-emission equipped trucks. 

DHD 600-510 Classic Duramax Center Link Steering Stabilizer Bracket

Our Improved DHD steering stabilizer bracket is now a 3-sided mount bracket. We recently redesigned our logo on the bar for more support which added 2 pounds to the bar for more strength. Better and stronger without a price increase!

Our DHD steering stabilizer bracket is a great affordable solution that will help support your GM pickups steering system. During hard launches, whether it be drag racing or truck pulling, the factory center link will flex and cause steering system damage. Our bracket is a direct bolt in unit that will use the front differential as its triangulated support in order to keep the front steering system straight and true.

Our bracket will work on all 2001-2010 GMC/Chevy 2500 & 3500 pickup trucks with factory ride height. This bracket will not work on lifted pickups, and trucks already equipped with a Cognito support kit.

NOTE: When using this brace for pulling or 4 wheel launches, the truck must have stock key or t-bolts all the way out. If you have your t-bars cranked in or you have a leveling kit, this product will not work properly.

How does it fit? Check out this brief install video below from our friends at XPLOITDIESEL.com.

Does it really work!? Check out how much steering system distortion occurs during a hard launch with and without the stabilizer installed.

New for the LML design is a roller bearing instead of the traditional Teflon pad. This will allow prolonged use without having to replace the Teflon pad.
