MACE ALLOY MAIN CAP GIRDLE TO SUIT HOLDEN CALAIS VS VT VX VY ECOTEC L36 L67 SUPERCHARGED 3.8L V6This V6 main cap girdle is designed to reduce "capwalk", stop block web flexing and eliminate cracking of the main caps block webs; this is achieved by boxing in the main caps. Our light weight girdle evenly distributes load and dampens harmonics by bolting the main cap studs together to create a super strong rectangular cage.

This V6 main cap girdle is designed to reduce "capwalk", stop block web flexing and eliminate cracking of the main caps/block webs; this is achieved by boxing in the main caps. Our light weight girdle evenly distributes load and dampens harmonics by bolting the main cap studs together to create a super strong rectangular cage. The brace nearly doubles the main web support area in the engine. Securing the loose end of the main studs provides stability unequaled even by a 4-bolt mains setup.

In addition, due to the close proximity of the main stud girdle to the crankshaft and rods it also aids in stripping oil off of the crank, which in itself yields a net gain in HP.

Fabricated from 16mm thick high strength aluminium, these girdles are ideal for use in high rpm/high horsepower applications where block rigidity is critical.

  • 1 X Main cap girdle

Vehicle Fitment Guide


Notes:

  • The girdle will require slight modification for a perfect fit. Generally speaking, the oil pick up will require lengthening, and small sections of the block/girdle will require slight modification to prevent/alleviate any fouling.
  • Worst case scenario, if there is a large variance with the block you are using, the girdle will need to be skimmed to make the mating surfaces flush again.
  • Custom length main studs are required. These can be purchased from any authorized ARP dealer.

Real good quality. Better price then Menards. Missing screws.
Size: 5.5 INCH
Real good quality, very sturdy, and it came with screws and drywall anchors. I would recommend. Only thing is it came with twice the drywall anchors that I needed and missing 2 screws. Not a big deal for me, but someone without screws laying around would have to buy a whole box for 2 screws. Other then that, it’s a good product and would buy again.

Amazing quality brackets
Size: 7.25 INCH, Size: 7.25 INCH
When I received my order I was very impressed with how the brackets were packaged. Once opened up, the steel brackets are amazing quality, and comes with all the screws needed. The only downsize is the screws are lower quality so by the time I got them in they were stripping where the screw driver sits. Same with the drywall attachments. I only used two dry wall attachments per shelf because I didn’t want to ruin my walls with giant holes. It seems to hold adequate weight. I put the regular screws in the bottom holes and through the wood to secure shelf from sliding. Overall I am very pleased. I will be ordering again when I do my bathroom shelves.

Keep ample supply of batteries nearby
Color: Graphite, Style: Keyboard
his keyboard does exactly what I needed it to do—stay quiet. No loud clack-clack echoing through calls, even on sensitive audio. It’s a solid choice if you’re working around microphones or just prefer a softer typing sound. Connectivity was easy, and it’s been reliable so far. The keys feel comfortable once you get into a rhythm. That said, the spacing is just slightly different from my previous keyboard—barely a millimeter or so—but it’s enough to throw you off at first. There’s definitely a short adjustment period before your fingers recalibrate. Also, it doesn't blow through batteries super fast, but I promise you'll want some spares handy because Murphy's Law dictates that you will be in the middle of something important when they go out! Overall, a dependable, low-noise keyboard that works well once you get used to the feel.
