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
  • (36) M6x1.0x16mm Socket Cap Bolts
  • (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.

A favorite for my boys!
Color: Hambone Super Chewer, Size: M/L
My dogs love this toy, it satisfied their need to rip up a toy and still allowed them to play long after the top layer was torn apart to enjoy! It bounces well and has still held up with my chewers, this is still one of my dogs favorite toys to play fetch with!

Great toy
Color: Hambone Super Chewer, Size: M/L
My dog loves this toy so much. He's not quite so aggressive with his chewing, now that he's getting older, but this toy lasted through his younger years, and recently started to show signs of wear. He was so sad when I threw it out, that I had to replace it. Glad it still exists - we got the first one probably 5 years ago.

Great for heavy chewers
Color: Hambone Super Chewer, Size: M/L
Our dog is a hard core chewer! This toy is very durable. Even the covering has lasted. We assumed we would need to take the cover off right away but it’s still going after 3 months. It’s definitely chew resistant

Great treat dispenser
Color: Hambone Super Chewer, Size: M/L
Great rubber toy, the outside fabric did not last long, so glad that it is a treat holder/dispenser otherwise it would have been done for in about 10min. The opening for the treats is pretty small so can only fight thinner broken up treats. Great for larger dog that likes to dissect her toys, keeping her entertained longer and no fluff all over the house

My dog loves this toy!
Color: Hambone Super Chewer, Size: M/L, Color: Hambone Super Chewer, Size: M/L
My dog LOVES this toy. It is so cute. It was a little smaller than I thought it would be, but it’s actually the perfect size for him. He carries it everywhere with him, and if he happens to have forgotten it, we say “go get your pig” and you can see it click in his head that he forgot it, and he runs to get it. He loves to drop it to make it bounce. He is 9, he used to instantly rip anything to shreds, but he seems to have gotten a little more delicate in his older age and after a few weeks hasn’t gotten through to the harder toy yet. Once this toy bites the dust, we will have to buy him another because of how much he loves his pig.
