PART # DESCRIPTION FOR 17-23 M-EIGHT 0926-2973 Standard, 6mm valve stem (uses factory retainers) PART # DESCRIPTION FOR 05-17 88”/96”/103” TWIN CAM, 04-22 XL, 09-12 XR 1200 (EXCEPT RH SPORTSTER) 0926-0852 7°, 7mm valve stem w/ stock triple keeper groove ENDURANCE BEEHIVE® VALVE SPRINGS WITH TITANIUM RETAINERS •Feuling BeeHive® Endurance springs are direct bolt-in replacements, no machining or rocker box clearancing required •M-Eight: up to .565” cam lift •Twin Cam: up to .650” cam lift •Machined from premium-grade hi-tensile chrome silicon single-conical ovate wire •Shot-peened with specially processed thermal heat treat and super NexTex® finish for fatigue life needed to exceed high demands of V-Twin engines •Use a much smaller and lighter weight retainer to reduce valve weight and create quicker rev and smoother motion •Available for 7mm or 6mm valves •Kits include: Endurance BeeHive® valve springs, optional lightweight Titanium retainers, machined spring seats, seat shims, valve locks and a set of premium Viton® valve seals equipped with spring-loaded valve stem wiper system •Twin Cam specs: seat lb./ installed height; 198 lb. at 1.685” (.535” lift), 194 lb. at 1.703” (.553” lift), 190 lb. at 1.724” (.574” lift), 187 lb. at 1.754” (.604” lift), 185 lb. at 1.780” (.630” lift), 160 lb. at 1.800” (.650” lift),375 lb. at 1.150” (open height) coil bind at 1.100” •M-Eight specs: seat lb./ installed height; 134 lb. at 1.375” (.405” lift), 127 lb. at 1.405” (.435” lift), 125 lb. at 1.415” (.445” lift), 121 lb. at 1.435” (.465” lift), 116 lb. at 1.455” (.485” lift), 113 lb. at 1.470” (.500” lift),109 lb. at 1.490” (.520” lift), 103 lb. at 1.520” (.550” lift), 226 lb. at .970” (open height), coil bind at .920” •Feuling® BeeHive® valve springs must be installed at the correct OPEN HEIGHT, matching max lift to the open height spec of the valve springs •Made in the U.S.A. NOTE: Feuling® BeeHive® valve spring kits are direct replacement with no machining or rocker box clearance required up to .650” lift for 05-17 Twin Cam. Larger camshafts require valve guide machining for seal to retainer clearance. 0926-0852 0926-2973 PART # DESCRIPTION 0926-3138 For 17-23 M-Eight w/ factory style 6mm valve stems and triple groove HIGH-LOAD BEEHIVE® VALVE SPRINGS WITH TITANIUM RETAINERS FOR M-EIGHT •M-Eight High-Load springs are machined from a premium-grade hi-tensile chrome silicon single conical ovate wire, shot-peened with a specially processed thermal heat treat and super NexTex® finish to give these valve springs the needed fatigue life to exceed the high demands of V-Twin engines from stock to performance •Valve springs are a direct bolt-in replacement, no spring seat or rocker cover machining required up to .565” lift •Springs will accommodate over .600 cam lift, but will require spring seat pocket machining on the cylinder heads to set correct spring open height •Smaller lighter weight retainers which drastically reduce the valve weight creating a quicker revving and smoother motion than comparable dual or single valve springs •Eliminate valve spring separation, maximize stability, reduce valve-train noise and harmonics •Packaged as a matched set and must be installed at the correct OPEN HEIGHT •Matching max cam lift to the open height spec of the valve springs is essential for optimal valve-train operation and spring life (see included spring spec chart) •Kit includes: matched set of Feuling® High-Load BeeHive® valve springs, Titanium retainers, machined spring seats, seat shims, valve locks and a set of premium Viton® valve seals equipped with a spring-loaded valve stem wiper system •Bolt in up to 565 lift for M-Eight •Fit up to .600” lift •M-Eight specs: seat lb./installed height; 151 lb. at 1.475” (.485” lift), 144 lb. at 1.498” (.508” lift), 143 lb. at 1.501” (.511” lift), 140 lb. at 1.511” (.521” lift), 124 lb. at 1.562” (.578” lift), 120 lb. at 1.582” (.592” lift), 304 lb at .990” open height, coil bind at .945” (cam specs measured on the lifter at .050” lift with 1.61 rocker arm ratio) •Recommended for .540”+ lift camshafts •Made in the U.S.A. NOTE: These springs are ONLY recommended for large lift camshafts like Reaper® 592 Cam PART #0925-1265 and RACE style engines as these valve springs have increased load and if used on smaller cams will create extreme rocker arm deflection. NOTE: Valve seat cutter and pilot may be needed to achieve correct valve spring installed height on large lift camshafts.
