DNM Preload MTB Rear Suspension Shock 165 x 35 mm - Coil Upgrade

In this review of the DNM Preload MTB rear suspension shock, the bottom line is simple: it is a solid, no-frills coil upgrade for riders who need a reliable replacement shock with flexible installation options. Designed for XC bikes and even mobility applications like electric wheelchairs, this shock stands out for its one-piece dark hard-anodized AL-6061 body and a hard chromed 10 mm shaft, offering durability and predictable performance for everyday trail use and commuting. The inclusion of extra bushings and a preload adjustment makes installation and fitment easier across slightly different frames.

Key Features

• One-piece AL-6061 body: delivers a sturdy, corrosion-resistant housing that holds up to regular use and keeps the shock performing consistently.
• Hard chromed 10 mm shaft: provides a smooth, durable piston rod surface that reduces wear and maintains rebound feel over time.
• Preload adjustment: allows riders to tune sag and ride height quickly to match rider weight or cargo for a more controlled feel.
• Extra bushings included: two 8 mm x 24 mm bushings plus an 8 mm x 50 mm spare make it easier to achieve proper fit without extra shopping or modification.
• Compact travel and eye-to-eye size: the 165 x 35 mm size is suitable for many short-travel rear suspension platforms and lightweight riders seeking a firmer coil option.
• Five-year warranty: the included long warranty reflects the manufacturer's confidence and reduces ownership concern for long-term use.

Who It's For

This shock suits riders who want a dependable, entry-to-mid-level coil rear shock for cross-country trails, commuter bikes, or mobility devices. Riders who prefer a straightforward mechanical setup with preload tuning rather than electronic or air systems will appreciate the simplicity and durability of the hard-anodized body and chromed shaft. The 165 x 35 mm size makes it a match for frames designed for short rear travel.

Riders who need very fine-tuned damping, progressive mid-stroke support, or adjustable rebound/compression controls should look elsewhere, as this unit focuses on basic preload adjustment and solid mechanical construction rather than advanced suspension tuning found on higher-end shocks.
