Main Caps Tall Boy Billet IE 4140 (VW 4 CYL)The tall boy VW 4 cylinder main caps are carefully crafted, in house, from USA 4140 alloy steel.

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".

Polished Everyday Crossbody, Though Priced Like a Designer-Branded Bag
Color: Vanilla/Acorn
This crossbody bag has a clean, classic look that works well for everyday use, errands, travel, or casual outfits where you want something more polished than a basic purse. The north-south shape gives it a slim profile, so it does not feel overly bulky, but it still has enough room for daily essentials like a phone, wallet, keys, small cosmetics, cards, and other small items. The zipper closure is a practical feature because it keeps everything more secure than an open-top bag, especially when walking around, shopping, or traveling. The front and back zippered pockets are also useful for items you want quick access to, like a phone, receipt, lip balm, or transit card. I like that the layout keeps the bag organized without making it feel complicated. The material is mostly PVC with some polyester and polyurethane, so it has more of a coated designer-bag feel rather than soft genuine leather. That makes it easier to wipe clean and more resistant to everyday marks, but buyers should know they are paying more for the brand/style than for leather construction. The bag feels structured and presentable, but it may not have the same long-term aging or softness as a real leather crossbody. For comfort, the crossbody style is convenient because it keeps your hands free and distributes weight better than carrying a small handbag by hand. It is best for people who want a stylish everyday bag, not someone looking for a large tote or something that can carry bulky items. For pricing, similar branded crossbody bags usually range from about $80–$200, depending on the brand, size, material, and whether it is leather or coated canvas/PVC. At around $180, this is on the premium side for a PVC-blend crossbody, but it is fairly typical for the Michael Kors price range. Overall, it feels worth considering if you like the style and brand name, but value-focused buyers may want to compare sale prices or color options before paying full price.
