DNM Preload MTB Rear Suspension Shock Absorber 160 x 35 mm - Coil

In this review of the DNM Preload MTB rear suspension shock absorber the bottom line is simple: riders seeking a reliable, well-machined coil shock for XC bikes or retrofit electric wheelchairs will appreciate its build quality and easy installation options. The shock stands out because of its dark hard-anodized AL-6061 one-piece body and a hard chromed 10 mm shaft that deliver smooth action and corrosion resistance. The included extra bushing set and clear sizing choices make it a practical upgrade for those replacing worn stock shocks.

Key Features

• Hard-anodized AL-6061 body: One-piece construction improves durability and resists wear during extended riding or frequent use.
• 10 mm hard chromed shaft: Smooth, low-friction motion helps maintain consistent suspension performance and reduces pitting over time.
• Preload adjustment: Simple preload lets riders tune sag and initial spring feel for their weight and preferred XC setup.
• Extra bushings included: The package supplies 8 mm x 24 mm top and bottom bushings plus an 8 mm x 50 mm spare for easier fitment into a range of frames.
• Multiple sizes available: Choice of eye-to-eye and travel lengths (including 160 x 35 mm) allows matching to common rear triangle geometries.
• 5-year warranty: Manufacturer confidence and a long warranty period add peace of mind for regular riders.

Who It's For

The DNM preload rear shock is best for cross-country cyclists and owners of compatible electric wheelchair frames who want a straightforward coil upgrade that balances durability with simple tuning. It suits riders replacing an old shock or those who need bushings and basic preload control without a complex damping system.

Less suitable are downhill racers or riders seeking advanced external damping adjustments, as this unit focuses on robust construction and preload rather than multi-stage damping or remote lockout features. If you need high-end tuneability for aggressive trail use, look to shocks with more elaborate damping controls.

Pros & Cons

Pros

• Solid one-piece AL-6061 body offers longevity and resistance to corrosion for trail and daily use.
• Hard chromed 10 mm shaft provides smooth operation and reduces wear on seals and bushings.
• Extra bushings and hardware simplify installation into different frames and reduce fitment guessing.
• Long warranty period gives confidence in the product's durability and support.

Cons

• Limited to preload adjustment only, so advanced riders may miss more detailed damping controls.
• Available travel options are modest, so it is not suited for heavy-duty downhill setups.
