Over 35 years we’ve seen a lot of trends, designs and products in the world of high performance coilovers. Inexpensive coilover options sometimes are great for the short-term, but when these shocks need servicing or repair you usually have to replace the entire unit and possibly dealing with a company 7,000 miles away. We incorporate decades of experience in manufacturing and racing in every coilover we produce. Sourcing materials in the U.S.A. and manufacturing here in Los Angeles, California – Aldan can offer high quality, race winning coilover shocks, built to stand the test of time – all at a great value.

So what goes into an Aldan American Coilover?

  1. Monster Shock Mounts™

Quality? Oh yeah! We CNC machine our coilover shock mounts out of 2.0” solid bars of aircraft grade, 6061-T6 billet aluminum. This design and material we use is incredibly strong and ultra-light weight when comparing to forged aluminum and steel welded, loop style mounts. Our Monster Shock Mounts™ can run polyurethane bushings or spherical bearings.

  1. Adjustment Knobs

Set it once, or always tuning? Our adjustment cams are machined out of solid brass bar stock. The brass is ultra strong an non-corrosive when compared to steel. Plastic? No Plastic here. We machine our adjustment knobs from solid 6061-T6 high strength aluminum bar stock, built for extreme use. Easily adjust your shocks by hand for quick tuning on the fly.

  1. Spring Collet

On a coilover shock the coil spring used works to suspend your vehicle. A well built, high quality spring collet with proper fit & finish is important to keep the coilspring in place and to keep everything set on the coilover. We machine our one-piece spring collets out of solid 6061-T6 billet aluminum. We machine a contour on our collets that not only looks great, but also provides additional clearance when comparing to competitor offerings. For fit & finish our Monster Shock Mounts™ seat flush in our spring collets for proper fitment & additional strength.

  1. Shock Shaft

Yes, there’s some technology here. We run heat-treated, high strength shock shafts in all of our coilovers. Offering 5/8” and 9/16” O.D.’s depending on the model – Our shafts are chromed and finish ground before assembly which drastically reduces seal friction, providing a longer life cycle to our coilovers.

  1. Shock Seal

We’ve developed a one-piece seal design built to handle whatever road you’re looking to take. Low friction, Viton seals & o-rings allow our seals to handle extreme heat and abuse. Black anodize finish allows removal so these shocks can be rebuilt, revalved or serviced when desired. Our finished ground shock shafts matched with this one-piece design provides a smooth ride built to handle the pressure.

  1. Coilover Shock Body

Shock bodies are the foundation to keeping it all together in a coilover. 6061-T6 aluminum is used on our shock bodies because it’s light, strong and runs cooler when comparing to steel. High quality? Yes! We run a standard thread on our bodies which is great for street use. Depending on the shock model, our shock bodies come with a machined, anodized or polished finish.

  1. Coilspring Retainer

A spring retainer like the spring collet is going to hold the spring in place. The retainer is going to allow you to adjust the spring for ride-height and performance. Our retainers are CNC machined from extruded 6061-T6 aluminum with a matched standard thread for a superior fitment and cinch to our shock body. Tight tolerances and matching the fit, form and functions are the difference in a high quality coilover – We provide this on everything down to our spring retainers. Designed to work with most spanner wrenches for easy adjustment and backed up with a lower lock nut on select models for excellent holding and adjustment capabilities.

  1. Monster Shock Mounts™ – Lower Mount

Our lower Monster Shock Mounts™ are a thing of precision and beauty. We CNC machine these from our 2.0” solid bars of aircraft grade, 6061-T6 billet aluminum. On the inside of the mounts we machine the internals and finish with a special thread to seat into our shock bodies. Our thread is then hit with a high temp thread locker used by the US military and several off-road and racing shocks operating in the most extreme conditions. We’ve designed our lower Monster Shock Mounts™ to run polyurethane bushings or spherical bearings.

Obsessing over quality and performance, while manufacturing here in the USA is what we do. When we save, you save – bottom line.
