Transform Your Walker Evans Shocks Into a Tunable Performance Suspension System

SDI Valving Kits are engineered for Walker Evans 2.0 and 2.5 shocks found on 2014-2025 Polaris RZR XP 1000 and XP Turbo models. Each kit includes a performance piston, optimized valving components, and a tuning chart with multiple configurations for different riding styles and terrain.

Each kit is enough for a single shock

Features & Specifications

More Than Just A Re-Valve

Most valving kits only provide replacement shims.

SDI Valving Kits include a performance piston, valving package, and tuning guide that allow your Walker Evans shocks to be tailored to your specific riding style and terrain.

By improving oil flow characteristics through the piston while providing multiple valving configurations, these kits create a suspension system that is more controlled, more predictable, and easier to tune than factory configurations.

What's Included

Every SDI Valving Kit Includes:

✔ SDi Performance Shock Piston

✔ Complete Valving Package

✔ SDI Tuning & Valve Chart

✔ Multiple Recommended Valve Configurations

The included tuning chart allows riders and suspension tuners to select valving combinations based on vehicle setup, terrain, and performance goals.

Because one valving setup for everyone is about as logical as one tire pressure for every trail.

The SDI Advantage

Performance Piston Design

The piston is the heart of your shock.

SDI performance pistons are designed to provide improved oil flow and damping control compared to factory configurations. The result is a suspension that reacts more predictably throughout the stroke while maintaining comfort and control.

Tunable For Your Riding Style

The included valve chart provides multiple valving options ranging from comfort-oriented trail setups to aggressive performance applications.

Improved Suspension Control

Proper piston and valving combinations help:

• Reduce harsh impacts
• Improve bottoming resistance
• Increase chassis stability
• Improve traction
• Enhance cornering confidence
• Reduce rider fatigue

Designed For Real Riders

SDI valving configurations are developed through real-world testing, not computer simulations alone.

The goal isn't to create the stiffest shock.

The goal is to create a suspension package that rides comfortably, handles predictably, and inspires confidence when the trail gets rough.
