The 546-HSP or best known as the HSP Billet Valve Covers for the 2011-2016 LML Duramax equipped Chevrolet and GMC trucks. The HSP Billet Valve Covers is a game-changer for the engine bay in the LML Duramax.

 

Why would you need the HSP Billet Valve Covers for the 2011-2016 LML Duramax?

The factory valve covers on the LML Duramax are less than stellar when compared to the rest of the engine bay. People have seen that when making changes to their engine bay and adding parts to clean up the engine bay the valve covers have always been overlooked. HSP Diesel saw this and this is why we went to work on the HSP Billet Valve Covers.

 

What do the HSP Billet Valve Covers do differently?

We start with the material we use on the HSP Billet Valve Covers, we use 6061 T6 aluminum. We do this because we want something that is going to hold up and show off our awesome CNC Billet machined parts. With the construction being of metal, you are able to have a powder-coated piece that sets off that engine bay and holds up to the elements.

Our additional breather kit will include all the necessary hardware to route the breathers behind the front cab mounts. This reroute will feature a 1/2 Inch NPT to -10AN aluminum 90 degree fitting to a -10AN nylon braided hose on each valve cover. This is an additional product that is not included with the standard valve covers. You must select the crankcase ventilation kit in the drop-down menu if you wish to purchase it.

 

What comes with the HSP Billet Valve Covers?

  • (1) Drivers side valve cover
  • (1) Passenger side valve cover

  • (4) M4-0.7x6mm Socket Cap Screws

 

*Special Note*

Running Change on these parts. These valve covers no longer come with O-Ring's we recommend using Grey RTV to create a proper seal.

 

What Does the HSP Billet Valve Covers fit?

  • LML: 11+ VIN Code 8

 

How do people know the VIN code?

Engine code is dictated by the 8th character of the VIN number. The 10th character is the year of the truck.

Really nice!
Color: Brown
Nicely made. The wood has a lovely finish and rich color. The compartments have a softer bottom so you don’t have to worry about scratching your glasses or other surfaces. Great assortment of compartment sizes to help organize your items. Kicking myself for not getting one sooner.

Beautiful and Functional - And A Great Price. Just Bought My Third One
Color: Beige
I just ordered my third Sumnacon square linen tissue box cover. This tissue box looks just like linen - but it's better because unlike real linene, it can be wiped down and cleaned. It is a soft linen color... it blends beautifully into any decor. Such an improvement over a cardboard tissue box. I got one for my bathroom, then ordered one for our bedroom. I just ordered another for the kids bathroom. It has a magnetic bottom which is great and the price is right. I've purchased big clunky ceramic tissue box covers in the past and these are far superior. Understated and very pretty.

Attractive & Practical
Color: Beige
Great quality tissue box cover. Solved a big problem. PU with a linen weave texture. Attractive finish. Weighty, magnetic bottom and a great fix for the tissues box falling into the floor every time a tissue is pulled. Solves a lot of issues.

Elevates your tissue box
Color: Beige
Very well made! Sturdy with nice look. The fabric can easily be wiped down if needed. Very pleased. The tissue box slides easily in and I like how the bottom is covered as well. Elevates the box for any room. Great value for the money! Bought two and plan to purchase another.
