This Stens V Idler is made with exacting specifications for direct-fit applications to leading brands of outdoor power equipment. Precision engineering ensures the v-idler installs easily without modifications or adjustments. V idlers provide just enough pressure to engage the belt and redirect motion. The V-shaped profile of this idler keeps the belt ideally positioned in the track. As the belt is in motion, the V idler both guides and tensions it for optimal engine performance. Stens offers both standard and heavy-duty V idlers. Standard idlers feature metal and composite pulleys to match OEM performance, long-life bearing components, bearings included (where applicable) and corrosion protection against the elements. Heavy-duty idlers feature riveted, welded and formed pulleys to match OEM design, heavy-duty bearings and seals for high RPM applications, bearings included (where applicable) and zinc or E-coating for maximum corrosion protection.
