2011-2016 Duramax 6.6L LML Complete Package

Build Your 2011–2016 Duramax LML Package

Choose the correct truck fitment, exhaust and CCS support period, then select your optional SOTF switch.

Year and Fitment

• 2011–early 2015: factory V-band downpipe connection.
• 2015.5–2016: factory 3-bolt downpipe flange.

Fits Chevrolet Silverado and GMC Sierra 2500/3500 pickups with the 6.6L LML Duramax. For 2015 trucks, verify the actual flange before selecting. Changed downpipes can alter fitment. Provide VIN, model year, cab, bed, wheelbase and modifications before fulfillment.

Included

• EZ Lynk AutoAgent 3 hardware.
• CCS 4-Week or Lifetime Lynk support.
• Selected SPS aluminized race pipe or 4-inch/5-inch downpipe-back exhaust, with or without a muffler.
• SPS 800010-U LML cooler upgrade kit with up-pipe, listed for 2011–2016 in the SPS dealer catalog.
• BOD DSP5 LML switch when SOTF Yes is selected.

SOTF

No is the default. Yes adds the LML switch for $57.60. SOTF files must be matched to the installed switch; without a switch, request a suitable single calibration. A 4-Week support period ends after four weeks; the installed tune remains. Lifetime support provides ongoing access to compatible files and updates.

Transmission Tuning

Transmission tuning is not included. EZ Lynk transmission tuning is a separate option for compatible 2015–2016 trucks with a T87 controller; confirm the controller before adding it.

Build Notes

Exhaust part numbers change with the year/flange selection. Retain the matching downpipe unless a separately verified replacement is ordered. Package photos show example components; supplied exhaust follows the chosen variant. Final EGR configuration, vehicle fitment and supplier fulfillment availability are reviewed before this draft is released.
