DMS Sheetmetal LSA Lid

Back In Stock!!


After the great ZL1 lid shortage of 2021 we noticed a void in the market. DMS decided to offer an affordable aftermarket lid that resembles the CTS-V lid with the coolant manifold in the rear and a smooth clean finish in the front. However, we didn’t stop there, the overall height is .200” taller than the CTS-V version leaving plenty of hood/strut bar clearance for guys running any type of lid spacers. We also increased the area above and around the intercooler brick to provide better airflow and greater air distribution. All flanges are 6061 billet aluminum while the plenum is .125”/.250” 5052 aluminum, all parts are cnc cut and hand tig welded right here in Weatherford, Texas.

Each lid comes standard with new gasket for the lid base and coolant manifold in your choice of either a -12an or -16an.

    Build quality is on point. Install was very easy. Like stock lid. Only thing I would advise customers of is the blower is a lot louder now. Sounds like a bad power steering pump. At idle and part throttle is very noticeable in the car. Not a bad thing. Just something to let potential buyers know. Intake temps have dropped over 20 degrees during a pull compared to ur zl1 lid.
