749234 Av V Me17 Up Valve Guide Exh 001

These AV&V Extreme Duty valve guides are built to handle the rigors of high-performance riding. By using a manganese bronze alloy, AV&V allows you to set tighter valve-to-guide clearances, which results in superior heat transfer and a noticeably quieter top end. The guides are CNC-machined for precision and include a Viton O-ring to seal off any oil paths between the guide and the head. A radiused and tapered nose helps with airflow and makes pressing them in much easier. With a Super Grip section for secure seal retention, these guides are a top-tier choice for Softail, Touring, and Trike models. Note that the inner diameter is unfinished and requires final sizing.
