PEFI Drive Shaft Saver The Original. The Proven. The World's Most Trusted Solution for the 998 Turbo. The Precision EFI Drive Shaft Saver is the product that put Precision EFI on the map. Trusted by riders, race teams, and dealers around the world, it has become our best-selling manufactured product, with thousands of units installed worldwide. Its reputation has been built on one simple principle: permanently solving one of the most common wear issues found on the Yamaha and Arctic Cat 998 Turbo platform. This isn't simply a spacer—it's a precision-engineered solution designed to protect your drivetrain, eliminate unnecessary wear, and extend the life of expensive components. Why You Need It Over time, the factory driveshaft and bearing assembly develops clearance between the shaft and bearing inner race. This movement may seem minor at first, but it allows the driveshaft to shift under load, creating unwanted driveline play. As the movement increases, it accelerates wear on the bearing, driveshaft, brake components, chaincase, and surrounding drivetrain parts. Ignoring the problem can eventually lead to costly repairs. The PEFI Drive Shaft Saver restores the proper fit between the driveshaft and bearing, eliminating unwanted movement before it causes further damage. It's one of the simplest—and most valuable—reliability upgrades you can install on a 998 Turbo. Precision Engineered Unlike generic spacers, the PEFI Drive Shaft Saver has been engineered specifically for this application. Its oversized flange provides maximum bearing support while ensuring the component sits perfectly flush against the assembly for an accurate, secure fit. Every unit is precision CNC-machined from high-strength billet steel before receiving a durable zinc coating for exceptional corrosion resistance and years of reliable service. Designed to meet the same quality standards as every Precision EFI product, it's built to outlast the original components. Quick, Bolt-On Installation One of the biggest advantages of the PEFI Drive Shaft Saver is its ease of installation. No driveshaft removal required No brake disc removal required No special machining Simple bolt-on installation Protect your drivetrain in minutes without major disassembly. Features Eliminates driveshaft-to-bearing play Restores proper bearing support Helps extend the life of the driveshaft, bearing, and drivetrain components Precision CNC-machined from billet steel Durable zinc-plated finish for superior corrosion resistance Oversized flange for maximum support and precise fitment Fast bolt-on installation Designed, engineered, and manufactured by Precision EFI Installation Installation Torque: 30 ft-lb (40 N·m) Installation Tip After torquing the Drive Shaft Saver, verify that the bearing remains perfectly square in its housing and is not cocked or misaligned. Proper bearing alignment ensures optimal fitment and maximum component life. Trusted Around the World With thousands of Drive Shaft Savers in service worldwide, this product has earned its reputation through years of real-world use in trail riding, mountain riding, drag racing, and high-horsepower applications. It's one of those upgrades that many riders install before a problem ever appears—because replacing an inexpensive wear-prevention component is far better than replacing a driveshaft, bearing, or chaincase. Simple. Proven. Reliable. That's why the PEFI Drive Shaft Saver has become the benchmark by which all others are measured.
