Kibblewhite takes a scientific "system" approach when designing their valve spring kits. Each component is designed to work with the others as part of the complete system. Kibblewhite's engineers use a proprietary design and simulation software, and draw on their 70+ years of design experience to create these systems. Kibblewhite's design, simulation, and manufacturing processes insure compatibility of the valve spring's force and natural frequency with the cam profile, valvetrain mass, system harmonics, and the engine RPM. Kibblewhite spring manufacturing partners are U.S.-based companies that are ISO certified. The Super-Clean Chrome Silicon valve spring wire they use is traceable back to Kobe, Japan, where some of the best spring wire in the world is manufactured. Combining the design and simulation protocols with this premium quality valve spring wire, and manufacturing processes including, heat treatment, stress relief, and shot peening, allow Kibblewhite to supply you with the best valve springs in the world.
Kibblewhite valve springs come complete with lightweight racing titanium retainers, chrome silicon springs, and lower steel collars as required for ONE engine. The Kibblewhite valve spring kit is easy to install and helps reduces valve float in the high revving engines, adding durability and reliability to the engine.
I did a complete rebuild, bought kibblewhite valves so these springs were a no brainer. Dont put money into a motor and reuse old springs, buy a quaility built spring and get the performance you need at full throttle.
I put the kibblewhite valves, and valve kit in my 05 rmz450, and 05crf250. they are the most durable and reliable parts out there, I ride the dunes a lot and never had an issue with anything so far.
I got a Honda CRF 250r 05 model which love to eat the valves up, and with that and not enough oil I blew up the whole motor, so I rebuilt her all the way and added a nice addon the valves, they bring alot more power and hold alot longer and dont have to be adjusted like the dumm old oem ones do.
dose this come with springs too
Next time you rebuild your top end make sure to use kibblewhite.Do it right the 1st time.
Everything you need to replace your springs is included and it is all really high quality stuff. Its really easy to install and prevents valve float. I installed mine on a 06 kx250f with kibblewhite valves and stage 2 Hotcams. Very good combo and adds a little durability to your top end along with the power increase.
Excellent product, good replacement for stock components strong and durable and have had many hours of trouble free riding comes with bottoms seats and retainers.
