EBC CSK Springs

By   on  Verified Purchaser

Easy upgrade from stock clutch springs


EBC CSK Springs

By   on  Verified Purchaser

I am pleased.


Not super stiff 10/10

By   on  Verified Purchaser

Not super firm but gets the job done. If you need replacement springs and don't want super stiff ones, highly recommend these bad boys.


Perfect replacement for the OEM part

By   on  Verified Purchaser

Slightly thicker than OEM diaphragm clutch spring. Fit perfect and operation was flawless.

Good improvement


CSK Springs

By   on  Verified Purchaser

I've had my new EBC heavy duty clutch springs on now for about 10 hours of ride time. So far my clutch is working great I do a lot of clutch up wheelies so I like my clutch to engage very abrupt. These springs definitely helped me get there.


Good transaction

What I ordered.


EBC CSK Clutch Springs

By   on  Verified Purchaser

New EBC clutch spring installed. No noticeable improvement over factory at all. Even the clutch lever resistance still feels soft.

Amazing


EBC CSK Clutch Springs

By   on  Verified Purchaser

Great price and quality.


Perfect fix

By   on  Verified Purchaser

Springs met expectations, they stiffened up the clutch and made everything much more solid.


Exactly what I needed

By   on  Verified Purchaser

Aftermarket springs worked great! The 15% over OEM strength they claim to have is exactly what I was looking for as I am operating at 10k rpm frequently and the extra pressure these springs apply to the clutch is needed to ensure I don't get slippage! Would buy again!


Installation was easy

By   on  Verified Purchaser

Improved performance of my ATV.


Good so far

By   on  Verified Purchaser

Works as advertised. No issues so far.

Questions & Answers


Will this fit 2023 Suzuki gsxr 1000

Yes, if you were to choose the 2023 Suzuki GSX-R1000 aftermarket clutch springs from our fit guide, you'll receive the correct springs to fit that fast bike.

By Tom

Would these work after a 308 Big Bore Kit

Just put a 308 big bore kit on my Sherpa and noticed the clutch may be slipping under heavy power in the higher gears. Do you sell heavy duty springs that would fix this?

They probably wouldn't hurt when compared to the stock clutch springs, and especially if they haven't been replaced in a while. EBC's clutch springs are somewhere between 10 or 15 percent stronger than the stock clutch springs, so it may help your situation. Still, before replacing the springs alone, you may wish to have a look at the clutch plates and steel separator plates themselves as well to be sure none of them are work beyond factory recommendations since clutch springs alone are not always the solution to a worn clutch.
