The Diamond Lane Finish

Premium hardware starts with premium ARP fasteners. Designed by a manufacturer with decades of experience in serious motorsports, ARP bolts bring the precision, material expertise, and rigorous quality-control philosophy demanded in high-performance applications. Diamond Lane Cycles begins with this premium foundation, not ordinary off-the-shelf hardware.

Next comes the Diamond Lane Cycles difference: every bolt is hand polished before its final finish. Show Polish delivers a brilliant, hand-polished appearance. For Black, Blue, and Gold, Diamond Lane Cycles applies its proprietary premium coating after hand preparation. The finish is designed to help resist rust, fading, and flaking while delivering the premium custom appearance your project deserves.

Premium ARP hardware. Meticulous hand polishing. Signature Diamond Lane Cycles finishing. These are the details that set premium custom hardware apart.

A common thread size does not establish compatibility with every project or component. Consult the appropriate service information for installation torque.
