Description
Product Overview
The SMT 2‑inch chrome fork tube extensions are engineered for Harley Davidson motorcycles with 39mm fork tubes. Constructed from high‑strength chrome‑plated steel, each extension measures 2 inches in length, adding front‑end height while maintaining structural integrity. The tops feature a subtle dome for a flush, attractive appearance that blends with stock triple trees. A 1/4″ side hole, hidden by the triple tree, simplifies assembly using a strap wrench.
Usage
These extensions are ideal for riders seeking a modest lift, frame rake correction, or a more aggressive stance without altering the suspension geometry. Perfect for cruising, touring, and custom builds, they integrate with stock springs and triple trees, ensuring a hassle‑free upgrade. Install them on any 39mm Harley fork tube to achieve a balanced, raised front end.
