Hand-Built in Japan, Engineered for the Lowest

326Power Japan occupies a unique corner of the suspension market. Built around the vision of Mitsuru Haruguchi, a legendary D1GP driver and 326POWER CEO, the brand started from a simple but uncompromising goal: build suspension that gets your car as low as possible without sacrificing control.

Every 326 power coilover, spring, and suspension component produced in Hiroshima reflects that obsession. At Springrates, we stock the full 326Power range for drivers who understand that stance and performance are not opposites.

326Power Chakuriki Coilovers: Built to Order, Built for You

The Chakuriki coilover line is the centrepiece of 326Power suspension and the product that established 326's racing credibility worldwide. Every Chakuriki kit is built to order and hand-assembled in Japan to your exact specifications, so no two sets are identical. That level of customisation goes far beyond what most coilover brands offer at any price point.

The engineering behind 326 coilovers is purpose-built for aggressive lowered setups. Monotube dampers are valved to match your chosen spring rates, ensuring the shock and spring work together from the moment the kit arrives. Robust 14mm and 20mm damper shafts handle the lateral loads and stress that come with slammed ride heights. A 26-step damping adjustment allows precise tuning across compression and rebound. Independent height adjustment and droop settings mean the damper retains full travel even at the lowest setting, where most competing coilovers begin to fail. Hexagon-style locking collars with pinch bolt locking eliminate slippage. Polyurethane bushes in eyelet-style bottom cups reduce compliance while handling side loads precisely. Camber-adjustable top mounts are included on MacPherson strut applications. 326power coilovers are not mass-produced. They are made specifically for the driver who ordered them, to the specifications they requested.

326Power Springs, Helper Springs and Supporting Components

326Power springs are available across the Charabane and Mazibane lines, covering a range of internal diameters and lengths to suit different coilover platforms. The Mazibane springs are manufactured by Swift Springs, delivering fatigue-resistant performance across 22 available spring rates from 6K to 100K kg/mm. That range covers everything from a daily-driven street setup to an extreme drift or show car application.

For drivers running ultra-low setups where standard springs reach their limits, 326Power's helper spring range, including the Majibane and Charabane helper springs, provides a last line of defence, maintaining suspension function when the main spring cannot. Supporting components, including the 360 bearing upper and lower mounts, reduce spring torsion under compression, producing a smoother, more consistent stroke at the lowest settings.

326 springs are sold in pairs with exact internal diameter and length specifications listed on every product page. At Springrates, we carry 326Power products with full fitment details, spring rates, and specifications so you know exactly what you are ordering before it ships.

FAQs

What makes 326Power coilovers different from other Japanese coilover brands?

Every 326Power Chakuriki coilover is built to order and hand assembled in Hiroshima, Japan, to the customer's exact specifications. No two kits are the same. Most coilover brands produce standardised kits in set spring rates and damper configurations. 326Power builds each kit from the ground up around what the individual driver actually wants, including spring rate, damping valving, and colour options. The brand was developed by Mitsuru Haruguchi, a D1GP driver and the 326POWER CEO, and the entire product line reflects a competition-level understanding of what aggressive, lowered suspension actually requires to function properly.

Can I run 326Power coilovers on my daily driver, or are they only for show cars?

326Power suspension covers a wide range of use cases, but it is worth being honest about what the brand prioritises. The Chakuriki coilover is engineered specifically for aggressive lowered setups, including slammed show cars and drift builds. Drivers who want maximum drop alongside reasonable daily drivability can achieve that with the right spring rate selection and damping adjustment. However, if smooth, comfortable daily driving is your primary goal with occasional spirited use, other brands may offer a more practical starting point. 326Power is for drivers who take stance seriously and are willing to tune around it.

What does "built to order" mean for 326Power Chakuriki coilovers and how long does it take?

Built to order means each Chakuriki kit is assembled in Japan specifically for the customer who ordered it, to their requested specifications, including spring rates and configuration. Because nothing is pulled from pre-built stock, lead times are longer than those of mass-produced coilovers. Delivery timelines vary depending on specification and demand. Contact Springrates before ordering if you have a specific deadline, and we will confirm current lead time expectations for your kit.

What spring rate range is available for 326Power Mazibane springs and who are they suited to?

The 326Power Mazibane springs are manufactured by Swift Springs and are available in 22 spring rates from 6K to 100K kg per mm. That range covers everything from a street-driven daily to an extreme drift or static show car setup. Lower rates in the 6K to 12K range suit daily street use with mild lowering. Higher rates from 16K upward are common in drift applications, where body control during hard acceleration and direction changes is prioritised over ride compliance. Springs are sold in pairs and listed with exact internal diameter and free length specifications.

What are 326Power helper springs and when do I need them?

326Power helper springs, including the Majibane and Charabane lines, are designed for ultra-low setups where the main coilover spring reaches full compression before the suspension stroke is complete. At extreme ride heights, standard springs can coil bind, eliminating damping control entirely. Helper springs sit between the existing spring and spring seat, maintaining light preload and keeping the suspension functional even when the main spring is fully compressed. If you are running a slammed setup with very short main springs, helper springs are a practical and often necessary addition rather than an optional extra.

Are 326Power springs compatible with other coilover brands like BC Racing?

Yes, in many cases. 326Power springs, including the Charabane and Mazibane lines, are available in standard internal diameters of 63mm, 66mm, and 70mm across multiple free lengths. These dimensions are compatible with many popular coilover platforms, including BC Racing. Before ordering, measure your existing coilover springs carefully to confirm internal diameter and free length match. If you are pairing 326Power Mazibane springs with an existing coilover and changing the spring rate by 4K or more, revalving the dampers to match is strongly recommended for optimal performance.

Does Springrates carry the full 326Power Japan range and how do I know what fits my car?

Springrates stocks 326Power coilovers, springs, helper springs, and supporting components, including 360 bearing upper and lower mounts. Every listing includes full specifications covering spring rate, internal diameter, free length, and fitment details so you can confirm compatibility before ordering. Use the vehicle selector on the product pages to narrow fitment for your specific make, model, and year. If your vehicle is not listed or you have questions about a specific setup, contact the Springrates team directly. We have been an authorised suspension retailer since 2005 and can confirm fitment and advise on the right 326Power configuration for your build.
