PART # DESCRIPTION 0926-3138 For 17-22 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. PART # DESCRIPTION 0926-0853 For 99-04 Twin Cam and 86-03 XL HIGH-LOAD BEEHIVE® VALVE SPRINGS WITH TITANIUM RETAINERS • Made from premium stress-relieved conical ovate wire with nitrided surface heat treatment, shot-peened surface enhancements and Nano Peen™ polish • Feature extremely high level of fatigue life • Use a much smaller and lighter weight retainer to reduce valve weight and create quicker rev and smoother motion • Designed to handle the highest demands of performance engines with high-lift, steep-ramped camshafts • Allow up to .750” lift cams; no rocker box clearancing required • Available for 5/16” valves • 10°, standard 5/16” valve stem and keeper groove • Kit includes: High-Load BeeHive® valve springs, lightweight 10° Titanium retainers manufactured from Ti-17 alloy and micropolished for enhanced fatigue life, machined heat-treated chromoly spring seats, seat shims, valve locks and a set of premium Viton® valve seals equipped with spring-loaded valve stem wiper system • Seat lb./installed height; 217 lb. at 1.789” (.574” lift), 215 lb. at 1.800” (.585” lift), 208 lb. at 1.819” (.604” lift), 200 lb. at 1.845” (.630” lift), 185 lb. at 1.900” (.685” lift), 170 lb. at 1.935” (.720” lift), 415 lb. at 1.215” (open height) coil bind at 1.125” • Dyno proven and track tested • 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 .574” lift for 99-04 Twin Cam and 86-03 XL and up to .700” lift for 05-17 Twin Cam. Larger camshafts require valve guide machining for seal-to-retainer clearance.
