Drive Shaft Shop 510298 Level 6 2000HP Right Rear Axle for 2015-2024 Mustang GT

The Drive Shaft Shop 510298 (RA8556X6) is a Level 6 direct-fit right rear axle shaft engineered for high-performance 2015-2024 Ford Mustang GT, EcoBoost, and GT350 models equipped with the factory 8.8-inch independent rear suspension. Designed to handle extreme power levels from 1400-2000 wheel horsepower, this axle represents the pinnacle of DSS engineering for fast street cars that occasionally visit the track for drag racing, road course, or autocross duties.

Premium Construction and Materials:

• Manufactured from premium 300M alloy steel with advanced heat treatment for maximum strength and durability
• Features a fixed outer CV joint design (non-plunging) that allows for greater suspension travel, ideal for lowered vehicles and adjustable suspensions
• Single housing construction provides superior strength compared to previous multi-piece designs
• Larger 115mm inner CV joint provides enhanced bearing support and load capacity
• 2-piece outer CV housing with 300M spline stub mated to fixed outer housing for exceptional strength
• 33-spline inner CV joint for maximum torque transfer

No-Bolt Design: This 2019+ updated design eliminates the need for bolts at the CV joint, simplifying installation while improving reliability. The fixed CV design has proven to be stronger and more durable than plunging designs in high-horsepower applications.

Direct Bolt-In Installation: Designed as a direct replacement for the factory right side (passenger side) axle shaft. Installation can typically be completed in approximately 3 hours with basic hand tools. Includes a 12-month manufacturer's warranty covering material and workmanship defects.

This axle is the right side (short inner) replacement for S550 Mustang models. For complete axle replacement, the corresponding left side axle (RA8555X6, part number 510297) is sold separately.
