Quality and Durability for the Long Haul

Strength and Service Life

All of Annex Suspension Group shock bodies start as a high strength carbon steel extrusion. Each cylinder is machined to a very tight tolerance before being subject to a series of QC processes including a final visual inspection by a dedicated technician. In fact, all of our components must pass a variety stringent QC processes before ever being placed into production. This rigorous testing ensures a long service life and repeatable shock performance, mile after mile.  

Maximizing Shock Life and Minimizing Friction 

Our steel piston rods are made using an oversized steel shaft that is hardened, then chrome plated for increased durability, oil seal life, and lower friction. Several years of development went into the creation of our piston rods to ensure responsive performance and safety.  

Perfectly Round

Each shock body is carefully inspected for a uniform diameter, a mirror finish, and a lack of taper. Any shock body that doesn't pass this inspection is scrapped. This strict process allows us to have great cylinder sealing for consistent performance and a longer service lift.

Perfectly Flat

Even the most minute flaw on a shock shim can change the damping force considerably. We have seen changes of as much as 15% just from a single shim being slightlyout of spec. It is critical that shims are checked before being used. We check each shim for straightness and perform a visual inspection of each shim before ever being put into a shock. These extra details may be glossed over in a mass produced shock but it's one of the ways we can assure consistent performance for our customers.

It's a Keeper

We want our products to be the last set of suspension you purchase for your car, period. High quality materials and coatings are used in Annex Suspension Group™ products to help achieve this goal. Each shock assembly undergoes a strict quality control process once when built, and once more before being shipped out. All of our shocks are hand assembled and individual dyno tested.

Superior Corrosion Resistance

Our shock bodies are extremely durable against corrosion in the worst of environmental conditions.

We use three separate electroplated applications of Nickel coatings and a final Nickel-Chromium (NiCr) hard sealant layer to ensure that all of our shock bodies can withstand the harshest of environments. NiCr is unique in that it is not prone to damaging electrolysis, which is a leading cause of seized spring perches on competing coilover systems. The result is a shock body that will always remain easy to adjust and will help to protect the spring perches from corrosion damage, on and off the track.

Why is Nickel-chromium so Durable? 

Corrosion resistant coatings are designed to protect metal components from degradation, harsh environments, and the strains of high-stress applications. Water, air, and electrolytes found in salt all do their part to attack the base metal used in a shock body so a good coating must be able to defend against these various elements simultaneously.  

Nickel-chromium (NiCr) has proven itself in automotive and industrial applications for decades as an extremely tough corrosion inhibitor. In order for a coating to protect the base metal, it must withstand being rubbed off after repeated use. Coilovers are a very challenging application. Years of road dirt and sand dig into and scrape off lesser coatings, revealing weaker sub-layers or even the raw base steel. NiCr is an extremely hard coating and is very good are resisting this kind of abuse, helping to ensure the longevity and lasting aesthetic appeal of your suspension.

No More Stuck Lock Rings

In states that experience heavy snowfall, salts and chemical de-icers like Magnesium chloride are used to melt away the snow on roads to provide traction for vehicle tires. This is great for road adhesion but can take a toll on improperly designed aftermarket suspension systems. If you live in these kinds of conditions and have experienced frozen or stuck lock rings, this is likely a result of electrolysis.  

Road salts and chemical de-icers contain electrolytes (yes, those kinds of electrolytes) that will literally fuse shock bodies and lock rings together over time with use. NiCr is not conductive, so damaging electrolysis is unable to take place leaving your suspension easy to adjust for years to come.

Durable Anodic Coating

We’ve opted to subject all aluminum parts - such as the camber plates, bottom brackets, lock rings, and even the adjustment knobs – to a deep sulfuric anodization process that results in the rich colors and even finish that can be seen on our products. This process not only looks good, but will protect the parts for years to come.

Protective Dust Boots

Thick and durable neoprene dust boots better protect shock shafts from scrapes and bruises, enhancing the longevity of internal seals and oil within. The neoprene remains flexible and is resistant to cracking and splitting as seen on lower grade suspension systems.

High Quality Bearings

All of the bearings used on our camber plates and spring perches come from class leading suppliers like Koyo® ensuring precision and long service life.
