Pedders Suspension Coilover Spring and Shock Assembly

Pedders Suspension: Engineering Coilover Excellence Since 1950

Pedders Suspension brings more than seven decades of suspension engineering heritage to their Coilover Spring and Shock Assembly lineup. Founded in Melbourne, Australia in 1950, Pedders grew from a small shock reconditioning shop into one of the world's most respected suspension specialists — and their coilover systems represent the pinnacle of that accumulated expertise.

The eXtreme XA: Pedders' Flagship Coilover System

At the heart of Pedders' coilover offering is the eXtreme XA Adjustable Coilover Kit — the flagship of their SportsRyder performance suspension range. These are not generic off-the-shelf units. Each kit is engineered to a specific vehicle application, with motorsport coil springs individually tuned to match the weight distribution and chassis dynamics of the target platform. Whether you drive a Ford Mustang, Chevrolet Camaro, Pontiac G8, Subaru WRX, or Tesla Model 3, Pedders has developed vehicle-specific spring rates and damper calibrations to optimize real-world performance.

Coilover spring and shock assemblies from Pedders combine the spring and damper into a single, compact unit, enabling ride height adjustment without compromising spring pre-load. The eXtreme XA system allows ride height changes of approximately 1 to 3 inches, achieved through a fully threaded mono-tube body and a high-grade steel lower mount — meaning you can dial in your stance without upsetting the suspension geometry or spring rate.

30-Position Adjustable Damping — Street to Track

What truly sets the eXtreme XA apart is its 30-position adjustable bump and rebound damping. With a simple click of the adjuster knob at the top of the shock body, drivers can move from a compliant, comfortable street setting to a firm, track-ready tune — and back again. This flexibility makes Pedders coilovers equally at home on the daily commute and at the weekend track day.

The gas-pressurized mono-tube design resists fade during sustained hard driving, while high-grade aluminum spring seats and an integrated dust boot help protect the shaft and seals for long-term reliability. Select remote canister variants — such as those available for the S550 Mustang — feature 52mm bodies that provide increased shock fluid volume to keep operating temperatures in check during endurance sessions.

Motorsport Roots, Real-World Reliability

Pedders backs their coilover assemblies with a 2-year warranty, underscoring their confidence in the durability of these components under real-world use. Factory-style bracketry ensures direct fitment into OEM mounting locations, keeping installation straightforward without the need for custom fabrication. The combination of motorsport technology, vehicle-specific tuning, and daily-driver practicality is the defining characteristic of Pedders' approach to the coilover category.

For enthusiasts who want a suspension upgrade that genuinely does it all — lowered stance, reduced body roll, adjustable response, and long-term durability — Pedders Suspension's coilover spring and shock assemblies deserve a close look.
