The tall boy VW 4 cylinder main caps are carefully crafted, in-house, from USA 4140 alloy steel. They provide extreme rigidity to the main bearing and crankshaft, and a flat foundation for a bedplate or crankshaft girdle installation.

These main caps are special because they are designed to work with a crankcase bedplate / girdle. Typically, the installation of those products requires machining small spacers, which go between the main cap and the girdle, bringing it up to the same level as the pan rails. What we found is that these spacers are very difficult to machine to the correct height. Even when done with extreme care, this compromises the installation and results in a warped girdle. Our solution to this is these Tall Boy Main Caps. These stand slightly proud of the pan rail as they come out of the box. They are then machined level with the pan rail, resulting in a perfectly flat surface for the installation of your bedplate / girdle, and the most rigid foundation for your crankshaft possible. In addition, the large profile and high strength material is much stronger and stiffer than the factory main caps.

If you are not using a girdle, please purchase our standard VW 4 Cylinder billet main caps.

Requires machine work including align bore & hone for fitment.

Main journal housing bore size: 2.3228"-2.3236".

Soft but Thinner Than Expected
Color: Pink, Color: Pink
This cashmere scarf is very soft and pleasant to the touch. The color is really nice. It is not too bright and is a bit darker than in the pictures, but still very close to the description. What I did not expect is that the scarf is not very wide and is quite thin. Because of that, I was a little disappointed.

A pricy scarf, but worth it for its warmth and softness
Color: Pink
Came in a box that would look like it was be used as a gift. Scarf was really soft and warm and the color matches the imaged shown on the product images. The length and size was true to what was said. Gave this as a gift for valentines day and the other person was happy to receive and and like it as well. I will say that the price of the scarf is pretty pricy but I guess that's why you have to pay for a pretty good quality scarf.

High quality sheepskin!!
Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural), Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
This sheepskin was purchased as a "chair cover" for my pets. It arrived with very nice packaging, along with detailed care instructions. The sheepskin was advertised as being"not white" online, and the company made very sure to state that the fur has an "off white/yellow" color. That was a little concerning for me, and I wasn't really sure whether it would have an off color, but it arrived exactly as described. There were no obvious discolorations, spots, or blemishes. In fact, it arrived as a soft "off white" color that is very beautiful and exquisite. The fur has a plush, even look, and there is no matting or fuzzy, "neglected teddy bear look" at all! I actually purchased another brand to see if I could distinguish the difference between the two. This particular sheepskin is by far the better of the two purchases. FYI: When the package was opened, there was no distinct odor. That's a huge plus! I will admit that the size was slightly smaller than expected. It really doesn't matter much in the space I'm using it for though. My miniature Dachshund loves it! If you're trying to find a high quality sheepskin, and you don't need to cover a very large space, this is definitely the one to buy!

The Quality of the sheepskin is awesome.
Color: Wolf Tip, Size: 2' x 3' (Natural)
This rug is a beautiful specimen of New Zealand sheep. The rug is very very soft, the rug is thick, and the brown tips are fabulous looking. All in all I'm very pleased with this purchase. The size is perfect as it measures 2' x 3'. I would buy again from this seller.
