Jaguar Coil Spring Shim (Vanden Plas XJ12 XJ6) - Rein MMD3565AA

Product Information

A suspension coil spring is designed to support the weight of a vehicle and ensure that it rides and handles with an appropriate amount of ride height and weight transfer and control, and is an integral part of the overall suspension system, which typically includes shock absorbers/struts, and anti-roll bars. As part of a total system, the coil spring is designed to support and control the vehicle’s weight at each corner, while the damper (shock absorber or strut) controls the energy of that spring as the weight acts on it, compressing and releasing energy in the spring.

Suspension coil springs are usually made of high-grade unalloyed or steel alloys.

• Loss of rate - As the car is driven and the coil spring is cycled and compressed, the spring material will lose rate and tension, softening from its original specification
• Breaking/cracking - Coil springs can fatigue to the point that they break or fail. This can happen at the front or rear, of any type of vehicle
• Cracked or flaking paint coating - Most coil springs are painted or powder coated for durability and rust resistance. Over time this can begin to crack and flake, off, allowing the spring material to corrode
• Sagging or uneven ride height - As a spring loses rate it can cause a loss of ride height, usually referred to as sagging springs. This can happen on any one corner but often seems to happen most often in the rear. A broken spring can also cause uneven ride height
• Clunks, clanks, and other noises over bumps - A broken spring can cause various noises over different types of bumps and at different speeds. This could be from the spring itself, or other components making contact where they should not be
• Rough ride, poor handling, lack of suspension support, or firmness - Once a coil spring loses enough spring rate, in addition to the above issues, you may notice a general lack of handling performance or the car may feel dull and not responsive. Additionally, you may notice a rougher-than-normal ride because the car will be ‘on the bump stops’ hitting potholes and large bumps.

About Rein

Founded in 2007, CRP Automotive introduced the Rein Automotive line of OE-quality replacement parts to the aftermarket. And in just two short years, Rein Automotive has become very popular among both warehouse distributors and professional repair technicians. Rein is the German word for “pure”, and has come to be synonymous with quality in the automotive aftermarket. A true dealer alternative.

The Rein brand includes a growing number of “better than OE” parts for selected applications. These parts address known weaknesses and premature failures of factory parts. Many of these replacement and service solutions have been developed with the help of our Innovation Council, a hand-picked group of experienced professional repair technicians and shop owners throughout North America.

All Rein Automotive OE-quality parts are backed by the CRP Automotive standard, and are backed with a ISO 9001:2015 quality management system certification. Each year, CRP Automotive ships thousands of Rein Automotive brand products. And with widespread NAFTA market distribution through strategically placed warehouses in Cranbury, New Jersey and Puebla, Mexico - OE-quality products like Rein Automotive are delivered to customers both faster and more cost-effectively than ever before.

In 2017 Rein partnered with FCP Euro in competing a W204 C300 AER car for the 2017 season. The partnership focused FCP Euro to dive deep into the Rein catalog offering, and hundreds of new products were added and integrated into our catalog. Hundreds of new packages were created not only using the full part pine up of Rein products, but also the entire family of CRP products like Pentosin.

Rein is also an innovative brand, winning numerous trade awards — including multiple new product innovation awards at the annual AAPEX trade show.
