PART # DESCRIPTION 0926-3138 For 17-24 M-Eight w/ factory style 6 mm 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 recommended for 0.530”+ lift camshafts •Direct bolt-in replacement, no spring seat or rocker cover machining required up to 0.592” lift •Springs will accommodate over 0.600” 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 •M-Eight specs: seat lbs./ installed height; 151 lbs. at 1.475” (0.485” lift), 144 lbs. at 1.498” (0.508” lift), 143 lbs. at 1.501” (0.511” lift), 140 lbs. at 1.511” (0.521” lift), 124 lbs. at 1.562” (0.578” lift), 120 lbs. at 1.582” (0.592” lift), 304 lbs. at 0.990” open height, coil bind at 0.945” (cam specs measured on the lifter at 0.050” lift with 1.61 rocker arm ratio) •Made in the U.S.A. NOTE: These springs are ONLY recommended for large lift camshafts over 0.530” lift such as the 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 #s 3801-0364 and 3801-0365).
