90% of the products in our store are in internal or external stock and we can often process your order quickly (varying from a few hours to a number of business days).
Naturally it is possible that a product has an (unexpected) longer delivery time.
Upon receipt of your order, we will always inform you about this and offer any available alternatives. So keep a close eye on your mailbox.
We deliberately provide stock information about our products afterwards, because many suppliers do not offer a ''stock link system'' and we do not want to show '' estimates '' in advance, like many other webshops do (which are often incorrect and give you wrong information in advance). We only want to give our customers actual information on the moment of processing the order so we don't mislead our customers.
If you need a product VERY quickly and you need to be sure that we have it in stock, please e-mail or call us or send a message via ''ask a question about this product'' below in the product description.
Ultra Series pistons combine JE’s premium features and all-new, industry-first technology into an off-the-shelf piston kit! This includes aligned grain flow technology, a proprietary JE technology that aligns the grain flow in critical areas of the piston to improve strength, and several other high-end features.
JE's revolutionary Perfect Skirt coating is one of the many technologically advanced aspects of the Ultra Series. It protects the piston skirts, reduces friction, while eliminating cold-start piston slap and false knock on computer-controlled engines.
All Ultra Series pistons will come standard with ceramic crown coating to help reject combustion heat for durability and better exhaust scavenging characteristics.
Thicker, premium-material wrist pins are another, strength-boosting feature of the Ultra Series line. Combined with unique Grain Flow Optimized forging technology, the Ultra Series is ready for huge power.
