Construction: Investment-cast and CNC-machined stainless steel. 5/16” x 18 t.p.i. stainless steel bar clamp hardware.
Fitment: The one-piece top clamp on this riser assembly fits rigid and rubber-mounted top trees with 3.5” (89mm) center-to-center mounting holes only (Wide Glide, Narrow Glide, H-D aftermarket trees, etc.) If your top tree has different mounting holes, Trio riser will not fit your motorcycle. Also, the holes on your trees must accept 1/2” O.D. hardware. The lower clamps are threaded to accept 1/2-13 mounting hardware (not included).
Details: The Trio riser cleans up and streamlines the triple-tree on your stock or custom Harley.
