MUST HAVE!!!!!
One of my favorite mods I’ve done so far used to slip on hard acceleration from 3rd to 4th sometimes now it stopped doing that very happy in how fast it got here no bs, I will definitely be buying more products in the future!!!

Brocks Clutch Springs
Great product, Easy install, Clutch pull still feels great and gears 1 through 6 all feel improved. *Note also replaced friction plates.

Good stuff
Work very well but the inside diameter of the spring dont fit the center hub correctly

Z900 heavy duty clutch springs
Not so much a problem with the OEM springs but as I added more power makers, clutch slippage at higher gears and rpm's began to occur. These springs looked like a winning solution for a reasonable price. So far, so good, clutch lever pressure feels slightly stiffer and the bike feels like its hooking up much better now though I must mention I replaced the clutch pack also so it's a combination of the two.

HD Clutch Spring Kit Z900
Great bang for the buck! Improves feel and shift quality. No more slippage from full throttle accelerations in 4th and 5th gear.

Worked perfectly
I ordered these as I have had an issue where my bike will drop out of gear during hard acceleration, usually in 5th. After installing the difference is night and day, I can now get to the redline in 5th and seems to pull harder in every gear in top revs. Well worth it.
