Chakuriki or Bucchigiri?

Both are the same 326POWER damper, built to order in Japan with the same seven anodize colors and the same 26-step damping. Bucchigiri adds a matched helper spring at every corner, plus the longer shock stroke and dedicated valving that requires, so the main spring stays supported at full extension and the car stays settled over crests and dips at low ride height. It sits one price rung higher at every rate. If you run a lot of droop or sit very low, Bucchigiri is worth it. If not, Chakuriki is the same kit without the helper.

How to Build Your Coilovers

STEP 1: Springs
By default, Chakuriki coilovers are fitted with 326POWER's Charabane springs. Upgrade to Majibane springs, manufactured by Swift, for a more progressive spring setup.

STEP 2: Spring Color
Charabane springs come in Pink, Green, Gunmetal, or Yellow. Majibane springs come in Green, Pink, or Gold.

STEP 3: Kit Colors
Choose a color for each aluminum part: damping adjuster, upper mount, upper sheet, spring lock sheet, bracket lock sheet, and bracket. All seven colors are free, so pick one throughout or mix them.

STEP 4: Dust Boot Color
Black is included. Blue, Green, Pink, and Yellow are available as an upgrade.

STEP 5: Helper Springs
Helper springs keep the main spring supported at full extension when running a lot of droop. Choose Charabane or Swift Majibane, front, rear, or both ends.

STEP 6: Helper Spring Colors
If you added helper springs, choose the spring color and the collar color.

STEP 7: 360 Bearing
The 360 Bearing sits between the spring and the locking collar so the spring rotates freely and binds less when steering. Available upper, lower, or both, at either end.

STEP 8: Super Thrust Sheets
Thrust sheets reduce spring friction and noise when turning, which matters most with stiffer rates. Colors are assigned at random by 326POWER Japan.

STEP 9: Hex Lock Seat
An upgraded lock seat in Standard or High Spec.
