SUNTOUR NUT SET FOR QLOC2 AXLE

The SR Suntour Q-LOC2 Axle Nut Set is an essential workshop spare designed to maintain the performance and safety of your SR Suntour suspension forks. The Q-LOC2 system is highly regarded for its rapid, tool-free wheel changes, utilizing a patented expanding collet design that slips smoothly through the hub before snapping securely into place. However, because the end nut is exposed to trail debris, rock strikes, and constant manipulation during wheel removals, the internal threads, tension springs, or retention clips can wear out or become lost over time.

This genuine factory replacement kit includes everything required to completely rebuild or refresh the tension end of your Q-LOC2 axle. Manufactured from durable, high-grade alloy and corrosion-resistant steel components, it ensures your thru-axle achieves a rock-solid clamp against the fork dropouts. By replacing a damaged or gritty nut assembly, you prevent the axle from binding inside the hub, stop annoying front-wheel play, and restore that crisp, reassuring mechanical click when locking down your front wheel.

Key Features

• Genuine Factory Replacement: Sourced directly from SR Suntour to guarantee 100% precise dimensional compatibility with your original Q-LOC2 assembly.

• Restores Tool-Free Operation: Refreshes the simple "push and twist" functionality, allowing for effortless wheel extraction without reaching for hex keys.

• High-Tensile Alloy Build: Engineered to withstand high clamping forces and structural trail vibrations without stripping threads or backing off.

• Complete Hardware Rebuild: Packaged as a comprehensive kit containing the primary adjustment nut, tension washer, and essential retention circlips.

• Corrosion-Resistant Finish: Treated with a durable coating to resist mud, harsh trail washes, and moisture oxidation over long-term use.

✅ Why This IS For You

• Experiencing Sticky Axle Removal: Perfect if your current Q-LOC axle is binding or hard to untwist, as a fresh nut setup restores smooth mechanical movement.

• Lost Small Parts During Maintenance: Ideal if you accidentally dropped the tiny retention circlip or washer into the workshop floor void during a fork service.

• Stripped Your Original Nut Threads: A mandatory upgrade if over-tightening or grit contamination has cross-threaded and ruined your factory adjustment cap.

• Want Routine Tool Kit Peace of Mind: Excellent to keep tucked away in your mobile travel kit or riding pack to prevent a broken clip from ruining a weekend trip.

❌ Why This May NOT Be For You

• Using a First-Gen Q-LOC or Q-LOC3 Axle: Designed specifically for the Q-LOC2 mechanism; it will not fit older original generation or newer modified Q-LOC3 setups.

• Own a Standard Threaded Thru-Axle: Completely incompatible with traditional bolt-on thru-axles from Fox, RockShox, or standard M15 threaded variants.

• Have a 12mm Road or Gravel Fork: This hardware kit is scaled exclusively for larger mountain bike diameters and will not clear compact 12mm road configurations.

BFC PRO TIP

When assembling the new Q-LOC2 nut set onto your axle shaft, apply a very light film of high-quality waterproof marine grease to the internal threads and the sliding face of the wave washer. This small step keeps out grinding fine sand and trail grit, while drastically smoothing out the mechanical rotation of the adjustment dial. When installing the final circlip, use a set of dedicated snap-ring pliers to avoid over-stretching the wire loop—over-expanding it can warp the clip, preventing it from snapping flush into its retention groove and potentially letting the nut back off mid-ride!
