I installed Gen 2 Spring kit on the Kymron XH42D and it made a huge difference!!! Made controls much smoother and there's no more jerking when moving the controls at a faster rate.

I just bought a huayee 16c and this is a must have!!! Keeps the pilot controls from jiggling around smooths out all boom operations!!!

I just installed a spring kit on my new SDLE20 and I’m very satisfied with the results. It smoothed my machine up tremendously. I’ll definitely purchase for my next machine also. If you’re on the fence about these making a difference, take my word that they work.

Got springs for pilot control for Cartiwell 1.6 PRO. Works firmly, with smooth handling. Thanks

The set made our machines go from uncontrollable to where a 5yr old could run them. Great product. If you have pilot controls there are a must

These springs should come factory on the machine! It took longer to find a 5mm hex head than it did to put them on. After the install of course to try it out. Probably 90% of the jerky movement was gone. If you use your machine an hour a month or 10 hours a day. Get a set.

What a difference the pilot spring kit has done to my mini excavator. 15 minutes to install and super easy. Night and day compared to the factory joy stick control. Thank you again!!!!

They install in seconds and make a huge difference.

Night and day difference on the mini skid steer with the pilot controls. Thank you!

Installed it in a 2 ton CAEL mini excavator. Drastically calmed down the overexagerated movements of the stick controls.

I recently purchased an AGT MX20R and while the pilot controls were reasonable for a mini X, I decided to buy a set of the GEN2 Pilot Control Springs after reading good reviews. The installation was very easy removing 1 bolt on each control, lifting the dust cap and installing the springs. The whole installation took just a couple of minutes and the result was excellent. My controls are noticeably smoother to operate. Definitely would recommend this simple upgrade

Super easy to do. Made a very big difference in using the pilot controls on my AGT QK18RXS-c. These should be put on at the factory.

Took about 3 minutes to install, great results and highly recommend.
Rhinoceros 12-9 gen 3

Went in easy and was a big change. Simple thing to make the controls easier to use with less jerking of the machine

Worked very well and very easy to install.
