Feuling, Econo Beehive spring kit, Ti top collars. Lift 585"

Upper titanium collars.
High-performance FEULING ECONO BEEHIVE valve springs with titanium retainers, designed to support camshafts with lifts of up to 0.585" at an economical price. These FEULING BEEHIVE springs are made from the same premium stress-relieved oval tapered wire as our HIGH LOAD springs, but developed for budget engine builds. They offer an excellent level of fatigue resistance and are designed to withstand the demands of high-performance engines with camshaft lifts of 0.585" or less. Dyno and track tested.
FEULING BEEHIVE valve spring kits are individually measured and labelled to their coil bind height / required open height. Our kits require you to measure the installed height and may require the use of the included shims. This allows you to set the springs specifically to your camshaft lift for quieter, smoother performance. Similar to setting your suspension to your weight and riding style.
• FEULING BEEHIVE valve springs use a much smaller and lighter retainer, drastically reducing valve weight, creating a faster revving and smoother motion than comparable dual valve springs.
• FEULING ECONO springs allow camshafts of up to 0.585" lift, with no grinding of the rocker box required.
• Eliminate valve spring surge, maximise stability, reduce valve-train noise and harmonics.
• Available for 5/16" and 7 mm valves
The kits include: FEULING ECONO BEEHIVE valve springs, lightweight 7-degree titanium retainers, machined and heat-treated chrome-molybdenum spring seats, seat washers, valve bushes and a premium Viton valve seal set equipped with a spring-loaded valve stem cleaning system.
Don't be caught out by inferior valve springs!
