MACE ALLOY MAIN CAP GIRDLE TO SUIT HOLDEN MONARO V2 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. The brace nearly doubles the main web support area in the engine. Securing the loose end of the main studs provides stability

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.

Comfy and warm
Fits well but the non-slip feature isn't great on carpeting

It is what I was looking for
Size: 10-13, Color: Black Lattice
The product is use for a at home slipper so that I don't need to wear shoes. I can relate my feet with a soft support on the bottom of my feet.

Great treat replacing for motivated dogs!!!
Color: Yellow
i use this ball strictly for training purposes with my Aussie who is super obsessed with balls. My dog seriously loves this ball. This has taken the place of treats. When we aren’t training the ball goes in a closet. So far it’s durable enough for our training session. (If we have a good session he is rewarded with having free access to the ball for a limited time, he enjoys a little tug so I normally hold the rope and let him have at the ball) for $10 id say it’s worth it. It’s definitely not indestructible but it is cheaper for me to replace these than buying treats every week as rewards.

Fun toy
Color: Orange
Well made. The puppies love it, BUT it is too hard for them at an early age ( 2 1/2 months. They ended up grabbing the rope. As they got 5-6 months they were fine. Make another model 1 inch smaller and half as hard Belgian Malinois & Doberman.

Durable & great deal
Color: Orange and Yellow
My foster German Shepherd has a jaw that's locked and loaded but love these cause I can play tug of war or fling it way across the yard. He's chewed or busted every ball he's received except these. I'm loving them. Very durable, bounces too really well and I can find it easily with the colors.
