SR SUNTOUR DUROLUX38

Gravity Has Met Its Match

When the mountain throws its worst at you, the DUROLUX38 throws it right back — with more speed, more control, and more confidence than ever before. Designed for the steepest lines, deepest compressions, and heaviest hits, this is SR SUNTOUR’s flagship enduro fork, reengineered to push boundaries on every descent.

Big Stanchions. Bigger Performance.

At the core of the DUROLUX38 are massive 38mm A7000-series alloy stanchions, paired with a hollow-forged crown and wide-pitch chassis for unrivaled stiffness and steering precision. Now lighter by over 200 grams, it’s more responsive and nimble without compromising on durability.

RC+ Damping: Fast, Fluid, Fearless

Developed through our elite WERX program, the new RC+ PCS Cartridge delivers our most responsive damping yet. A semi-open oil bath design increases oil flow, giving you buttery small-bump feel, rock-solid mid-stroke support, and big-hit control — all with fewer external adjustments and more meaningful performance.

External Rebound & Low-Speed Compression
Internal High-Speed Shim Stack Tuning
QSP Ports for Easy Serviceability
SKF Seals for Reduced Friction & Extended Life

Engineered for Extremes

A new 3D-machined bushing alignment system ensures ultra-smooth operation straight out of the box. Add an integrated fender, proven DUROLUX pedigree, and pro-level tuning options — and you have a fork built to go fast, stay composed, and take the hardest lines with ease.
