Aragosta 14K/6K Type E Suspension Kit w/ Rubber Upper Mounts for V37 Infiniti Q50 & Q50 Hybrid

Aragosta’s Type-E series of dampers are designed with both spirited street driving and comfortable cruising in mind. The Type-E includes several of high tech features of their Type-S and Type-SS high performance coilovers, including low-friction, WPC-treated inverted struts, height-adjustable rana springs, specially formulated synthetic damper fluid and Aragosta’s unique low friction seals. Additionally, the Type-E features 12-step rebound adjustment knobs (not available for some vehicles) on the bottom of each damper, as well as pillowball upper mounts (camber adjustable mounts available for some applications).

The Ultimate in Smooth Performance

The ultra-lightweight, high-pressure forged aluminum cylinder uses next-generation film treatment and Kashima coating. The special treatment of impregnating molybdenum realizes amazing lubricity of the cylinder itself. It is equipped with significant friction reduction and durability that cannot be compared with conventional hard alumite, and enables basic performance such as linearity, smoothness, and traction ability at a high level.

High-Precision Machining with the Highest Priority on Performance

Aragosta are particular about the processing accuracy of the cylinder and are able to execute surface roughness of 0.2 micron and 2/10000 mm for both aluminum and steel cylinders. In addition, an advanced honing treatment is performed to increase the surface accuracy and roundness inside the cylinder to the specified values. It is extremely rare for a damper manufacturer to perform processing at this precision engine on all of their cylinders.

Superior Finishing Technology

The steel cylinder / outer case is coated with cationic electrodeposition coating, which is considered to be the best in terms of rust prevention, impact resistance, and durability. It reliably electrodeposits to every corner of the thread for maximum coverage and increased lifespan.

Equipped with High-Performance Spring as Standard

All Aragostas are equipped as standard with rana springs, which embodies the ideal of a series-wound spring. In addition to high quality and high durability, the linear characteristics contribute to maximizing the damper performance.

Sharpened Internal Structure

Supporting Aragosta’s outstanding performance are damper pistons and needles that can control fine damping characteristics from extremely low speeds; covering a range from comfort to sports, dramatically improves traction performance. In addition, the external damping force adjustment mechanism gives a clear characteristic change to the 20-step adjustment range with a smooth and direct click feel, and corresponds to any setting.

High Hardness, High Efficiency WPC Processing

The inverted cartridge cylinder uses precision shot peening (WPC processing), which is the best technology for modifying metal surfaces. In cartridge cylinders with high sway resistance, the wear coefficient has been reduced and the oil film retention in the sway part has been significantly improved. It is a manifestation of manufacturing that puts the highest priority on performance to spend time and money on parts that are not visible.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
