So what goes into an Aldan American Coilover?

Monster Shock Mounts™

Quality? Oh yeah! Aldan American CNC machine their Coilover shock mounts out of 2.0” solid bars of aircraft-grade, 6061-T6 billet aluminum. The design and material they use are incredibly strong and ultra-lightweight when comparing to forged aluminum and steel welded, loop style mounts. Their Monster Shock Mounts™ can run polyurethane bushings or spherical bearings.

Adjustment Knobs

Set it once, or always tuning? Their adjustment cams are machined out of solid brass bar stock. The brass is ultra-strong and non-corrosive when compared to steel. Plastic? No Plastic here. They machine their 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.

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. They machine their one-piece spring collets out of solid 6061-T6 billet aluminum. They machine a contour on their collets that not only looks great but also provide additional clearance when comparing to competitor offerings. For fit & finish their Monster Shock Mounts™ seat flush in their spring collets for proper fitment & additional strength.

Shock Shaft

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

Shock Seal

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

Coilover Shock Body

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

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. Their retainers are CNC machined from extruded 6061-T6 aluminum with a matched standard thread for superior fitment and cinch to their shock body. Tight tolerances and matching the fit, form, and functions are the difference in a high-quality Coilover – Aldan American provides this on everything down to their 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.

Monster Shock Mounts™ – Lower Mount

Aldan American’s lower Monster Shock Mounts™ is a thing of precision and beauty. They CNC machine these from their 2.0” solid bars of aircraft-grade, 6061-T6 billet aluminum. On the inside of the mounts, they machine the internals and finish with a special thread to seat into their shock bodies. Their 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. They’ve designed their lower Monster Shock Mounts™ to run polyurethane bushings or spherical bearings.
