DESCRIPTION
When pushing your VW or Audi engine to the limits, a set of IE Billet Main Caps will provide a rigid foundation for your crankshaft, reducing main bearing wear. These main caps are in-house CNC machined steel for a massive upgrade over the stock cast main caps.
WHEN TO UPGRADE YOUR MAIN CAPS
The stock main caps are cast and lack the rigidity required for a reliable high power build. We recommend upgrading to a set of IE Billet Main Caps when building a performance engine exceeding 500HP. These VW/Audi 4 cylinder main caps are CNC machined in house to exacting tolerances for an easy fitting process. They provide extreme rigidity to the main bearing and crankshaft, which is a necessity for high horsepower engines.

- Replaces factory cast main caps
- Reduces main bearing wear
- In-house CNC machined
- Manufactured in USA
- Stable crankshaft platform
- Perfect for short block reliability

A true classic
Size: 7, Color: Maple Suede
One of my favorite shoes ever! Been wearing these since the 90's. They have changed a few things since then but I'd say the overall quality is still great. They fit true to size and are very comfortable right out the box. These are one of the most versitile pairs of shoes you can own. They go with almost any outfit. This time around I purchased the sand and beeswax colorways. If you've never owned a pair I highly recommend these.

Clark's Wallabee's are the best shoes ever made!
I was looking for a new pair of shoes, after one of my Clarks casual shoes (made in india) literally split in half. It only had 8 months of use! I was so angry, so much so that as a loyal Clark's customer I vowed to move on to another brand of shoe.
So I began my search, and search, and search... I just couldn't find any pair of shoe that exited me as much as Clark's did. I began to reminisce on my first pair of Clark's that started it all. The Wallabees.
The quality in craftsmanship, the nice thick leather, the stitching, and the indestructible weird looking jelly soles. These things could take a hit. I mean I wore them consistently for two years and they just wouldn't budge. I eventually needed something different, so I put them in the closet; only to come out when ever a pair of shoe wore out and I needed a something while I made another purchase. After about 2 years of that I realize I shouldn't be buying more shoes I should be wearing my wallabees. So I wore them for several more years until I finally decided its was time to part... What a mistake.
Here I had a pair a shoes that lasted me almost a decade I parted away for no real good reason. It took me many more years of wearing other Clark's and other brands to come to this realization. The Wallabee's are the best shoes ever made!
I broke my vow of not buying Clark's after that indian made piece of crap, and decided to buy these. To my surprise the wallabee's are no longer made in England or Ireland, but instead made in China!
I was sceptical as to how great the quality may be. I mean I lost faith in Clark's after all. But after careful inspection, these shoe's look, smell, and feel just like the originals. The craftsmanship looks the same as well (a little more modern support). I did some research and turns out China has one of Clark's best shoe factory in the world.
I can not judge these shoes by where is was made, but how they fare out with the old ones. So far I'm very very happy! I will wear these and put it to the test of time, and see if they will go for almost a decade as my originals did. At this point they once again take their place as my number one favorite pair of shoes.

Love them!
Size: 7, Color: Maple Suede
These are a classic! Amazing materials and product. If you have never owned a pair, be aware that the soles will get dirty quickly and visibly noticeable. I would say true to size in what you were in sneakers.
