Product Description
Proline 631603 Pro-Spec Scaler Shocks, 80mm-85mm: Rock Crawler (PRO631603)
This is a pair of Pro-Spec Scaler Shocks. Pro-Line proudly introduces the next evolution of RC shock performance with the Pro-Spec Scaler Shocks, engineered specifically for rock crawling applications requiring an 80mm–85mm length range. Built with precision CNC-machined aluminum shock caps, collars, bodies, and bottom caps, these shocks are designed to deliver durability, consistency, and exacting performance on technical terrain. Hard chrome coated steel shock shafts provide exceptional strength and wear resistance, while X-Ring seals ensure ultra-smooth, low-friction operation and superior leak prevention.
Like other Pro-Spec shocks, these Scalers stand out visually with striking chrome finishes and blue anodizing that bring both performance and scale realism to your build. Measuring within the 80mm–85mm extended length range (depending on rod end configuration), they are ideally suited for modern scale crawler setups that demand controlled articulation without excessive ride height.
Inspired by the proven design philosophy of Pro-Line's PowerStroke technology, the Pro-Spec Scaler Shocks arrive mostly pre-assembled. Simply add oil and they are ready for installation on many popular crawler platforms. Included dual-rate springs deliver realistic scale movement while maintaining the support needed to navigate rocks, ledges, and uneven terrain with confidence.
Features:
- Ready-to-Finish Assembly: Inspired by proven Pro-Line shock architecture, the shocks arrive largely assembled to reduce build time and complexity. Final oil fill is all that's needed before installation, getting your rig trail-ready faster.
- Dual-Rate Spring Control: The included dual-rate springs allow small bump compliance while maintaining support during climbs and side loads, improving traction and preventing the bouncy behavior common in single-rate setups.
- Purpose-Built 80–85mm Geometry: Instead of adapting longer shocks with internal spacers, these are engineered specifically for the ideal scaler length range. That means correct ride height, controlled articulation, and no trial-and-error setup.
- X-Ring Sealing Technology: X-Ring seals reduce friction while maintaining a superior oil seal, delivering consistent damping over time. Less maintenance, fewer rebuilds, and performance you can rely on trail after trail.
- CNC Strength Where It Counts: Precision CNC-machined caps, collars, bodies, and bottom caps create a rigid structure that resists deformation under load. The result is predictable suspension behavior and long-term durability that stamped or cast components simply cannot match.
