Aldan American Coilovers

Aldan American sorts its coilover shocks into five valving tiers rather than dozens of model names, so the series name on the shock tells you how much tuning control you get.

Striker - Double Adjustable

Striker is Aldan American's top tier, with 11 rebound settings and 6 compression settings tuned independently, for 66 total combinations. The body is 6061 billet aluminum, nitrogen charged, and factory rebuildable, and it carries a limited lifetime warranty to the original owner.

Regulator - Single Adjustable (Rebound)

Regulator is a rebound-only adjustable line with 11 settings, CNC-machined from 6061-T6 billet aluminum and hard anodized in a midnight black finish. It is offered with poly bushings (AS series) or spherical bearings (PAS series) and uses updated internals and seals over Aldan's older rebound-adjustable shocks.

Phantom - Single Adjustable (Rebound)

Phantom is also a rebound-adjustable line with 11 total combinations, sold alongside Regulator as Aldan's other single-adjustable option. Aldan American's own catalog does not spell out a feature difference beyond adjustment range, so treat Phantom and Regulator as two rebound-only product lines rather than assuming a performance gap between them.

SS - Single Adjustable (Compression)

SS flips the single adjustment to the compression side, with 6 compression settings, for owners who want to tune how the shock reacts to bumps and load transfer rather than how it returns.

500 series - Non-Adjustable

500 series shocks ship with factory-set valving and no external adjustment knob, built from 6061-T6 aluminum and nitrogen charged like the rest of the lineup. Aldan positions this as a true bolt-on for owners who just want adjustable ride height without tuning a knob.

Spring rate is sold separately from the shock on most kits. All five series share the same 2.5 in. I.D. coil spring fitment, so a given spring can carry over if an owner steps up from a 500 series shock to Striker later.

Aldan American sells true bolt-on coilover kits that reuse the factory mounting locations rather than requiring a separate conversion bracket on cars that already came with a strut or shock-and-spring front end. The 1967-1969 Camaro front coilover kit is one example, priced $711.99-$936.99 at the time of writing depending on spring rate and shock series, and it lowers the front stance 0.0-2.0 in. from stock.

Aldan also lists a double-adjustable front and rear coilover kit (300275) for the 2005-2013 Corvette C6, built on the same Striker-style valving. See our Corvette coilovers page for more on C5/C6/C7 fitment, and our coilovers by car hub for other vehicle-specific kits.

Aldan American, QA1, and Viking all build coilover shocks and vehicle-specific kits aimed at American muscle cars, classic trucks, and Corvettes rather than import tuner platforms, so the three brands get cross-shopped on the same build threads. Bilstein is the better-known name for monotube, OE-style shocks on later-model trucks and performance cars, which makes it a common comparison for owners choosing between a muscle-car specialist and a monotube factory-style shock.

Where Aldan American tends to stand out against QA1 and Viking is the spread of adjustment tiers sold under one series name, from the double-adjustable Striker down to the non-adjustable 500 series, all sharing the same 2.5 in. I.D. spring fitment so an owner can change tiers without changing springs.

Owner feedback on Corvette forum threads about Aldan American coilovers is mixed: some owners describe the shocks as soaking up potholes with no sideways movement in a turn, while others who paired them with a mismatched spring rate found an early setup harsh and bouncy on the street. That split points more at spring rate selection for the car's intended use than at the shocks themselves.

Ride height on an Aldan American coilover is set by threading the lower spring perch up or down the shock body, the same way as on most other threaded-body coilovers; see our coilover adjustment guide for the general procedure and a coilover spanner wrench to turn the perch without marring the finish.

On Regulator, Phantom, and SS shocks, the single knob only moves the one adjustment the series is built for (rebound on Regulator and Phantom, compression on SS). On Striker, the two knobs are independent, so compression and rebound should be set and road-tested separately rather than assumed to work together. 500 series shocks have no knob to adjust; only ride height changes.

Aldan American shocks are factory serviceable and rebuildable, and are nitrogen charged from the factory rather than needing a user-serviceable gas fill.
