The EPI White Primary Clutch Spring (CPDPW2) is a precisely engineered performance upgrade designed specifically for the 2026 Can-Am Defender HD11 with its advanced pDrive clutch system. Manufactured from high-quality chrome silicon wire, this spring is built to withstand the intense thermal stresses and frequent cycling typical of heavy-duty UTV CVT systems. EPI maintains a strict 5% tolerance on all their springs, ensuring consistent performance from installation through many years of use. This durability is particularly important for Defender owners who rely on their machines for demanding daily tasks and require a drivetrain that maintains reliability under continuous use.

From a performance perspective, the White Primary Spring enhances how your HD11 transmits power to the wheels. With a 2.5-inch load of 145 lbs and a 1.25-inch load of 280 lbs, this spring generally offers firmer engagement and a more aggressive shift rate compared to stock or lighter-duty options. It allows the engine to reach a slightly higher RPM before the clutch engages, resulting in a quicker, more responsive throttle feel. This enhancement is especially advantageous if you have equipped your Defender with larger, heavier tires or additional accessories, as it helps keep the machine within its optimal powerband longer, reducing the risk of bogging down during acceleration or climbing steep terrain.

This upgrade effectively bridges the gap between a work-focused vehicle and a trail-ready machine, ensuring your CVT operates at maximum efficiency. By optimizing the shift curve, the EPI White Spring reduces belt slippage and helps maintain cooler clutch temperatures, thereby extending the lifespan of your drive belt. Whether you're hauling heavy loads across the farm or seeking improved performance on weekend trail rides, this spring enhances your pDrive system’s responsiveness and overall capability, tailoring it to your specific driving needs.
