326POWER Toyota Crown GRS18, 20, 21 Chakuriki Coilovers

326POWER Chakuriki coilovers were designed with one goal in mind: to provide the utmost level of control and drivability while allowing you to lower your car to the floor.

Thanks to countless hours of R&D by legendary D1GP driver and 326POWER CEO Mitsuru Haruguchi, each Chakuriki Coilover kit offers a high level of customisation and personalisation far beyond those found on any other coilovers. Each component has been designed with low driving in mind, ensuring that your suspension can still function properly while your car is slammed to the floor.

Chakuriki Coilover Specs:

- 26-step damping adjustment using click adjusters 
- Monotube dampers, valved to suit your chosen spring rates Independent height adjustment and droop/preload settings (allows for full damper travel even at the lowest setting) 
- Camber adjustable top mounts (on kits for cars using MacPherson style suspension) 
- Robust 20mm-thick damper shafts Rubber dust boots 
- Hexagon-style locking collars with pinch bolt locking system 
- Eyelet-style bottom cups feature high-impact polyurethane bushes 
- Rubber spacers fitted to locking collars to prevent spring noise and stress on the    spring under lateral loads

Each Chakuriki coilover kit can be built to suit your specific requirements via the 326POWER Upgrade Scheme. Please check over the upgrade options below when ordering your coilovers.

STEP 1,2 & 3: Color Scheme - Blue, Black, Gold, Green, Orange, Purple, Red 
Choose your desired colours for your dampening adjuster, pillow upper mount and upper sheet colour. In addition, you will also choose any combination of the above colours for spring lock bracket lock sheet and bracket. Please use the Additional Notes option when ordering if you want to mix and match colours.

STEP 4: Majibane Spring Upgrade 
By default, Chakuriki coilovers are fitted with 326POWER’s Charabane springs. If you require a more progressive spring setup, you can upgrade to Majibane springs. These are manufactured by Swift.

STEP 5: Choose your desired Spring Colour and Spring Lock Sheet Colour.

STEP 6: Dust Boot Color – Black, Blue, Green, Pink, Yellow 
Choose the desired colour for the damper Dust Boots. The default colour is Black

STEP 7: Choose your desired Bracket Lock Sheet Colour and Bracket Colour

STEP 8: Spring Super Thrust Sheets come with all coilovers. These help to reduce spring friction and noise when turning, particularly with stiffer spring rates. Please note that it is not possible to choose a specific colour for the Spring Super Thrust Sheets; 326POWER Japan will include colour sets at random.

STEP 9: Helper Spring Upgrade 
If you plan on running a large amount of droop on your coilovers, you’ll want to have helper springs fitted. These ensure that the coilover spring isn’t unsupported when the damper is reaching its full extension. Which is usually the case, when weight is transferred away from a particular corner of the car (i.e when cornering hard or when jacking up the car). You can choose from the standard 326POWER Charabane helper springs or upgrade to the Swift Majibane helper springs.

STEP 10: 360 Bearing Upgrade 
On cars with MacPherson style front suspension, spring binding is a common issue when steering. This is because the coilover is trying to turn with your wheels while the other components remain captive. This puts a lot of pressure on the standard top mount bearing. The 360 Bearing sits between the spring and the lower locking collar and allows the spring to rotate freely, regardless of the coilover. If you want to make the process even smoother. You can choose to have 360 Bearings at both the top and bottom of the spring.

STEP 11: Sliding Upper Mount 

Sliding upper mount can be added to your coilover to gain extra clearance between front knuckle arms and coilover body on double-wishbone style suspension.  

STEP 12: Spring Rates – 4kg/mm ~ 100kg/mm 
Choose your desired spring rates depending on the type of driving that you intend on doing. Your dampers will be valved according to the spring rates that you choose.
