SULLIVAN PUSHROD 60in SEMIFLEXABLE BLACK/YELLOW 4-40 #518Nylon and Carbon filled Gold-N-Rods feature an exclusive spline design that reduces friction and eliminates sensitivity to dirt, dust and moisture. They are very easy to install -- a threaded stud screws into the inner rod, and a clevis attaches to the other end of the stud -- and they are versatile, as they are unaffected by fuel. They can be used for any part of the control system, and are made in sizes and lengths to fit just about any application. Clevises, studs and other hardware are included in all kits. To assemble, simply cut the pieces to length and glue or clamp (see hardware) the outer sheath in place. The threaded studs simply self-thread into the inner rod (easily done with a cordless drill) and the clevises thread onto the studs.
