Precision Engineering for Maximum Durability

SunCoast has taken the 48RE’s biggest vulnerabilities and engineered solutions that ensure long-term durability and superior shifting performance. The kit includes Raybestos GPZ clutches with steels, a high-flow transmission filter, a custom-machined overdrive pressure plate, and a billet accumulator piston, all working together to eliminate slippage, reduce heat, and improve power transfer. The billet intermediate servo, band anchor, and strut address common weak points in the transmission’s band actuation system, ensuring precise control and eliminating failures that plague stock units. With precision machining and premium materials, this rebuild kit provides a drop-in replacement with a straightforward installation process.

Triple-Disc Billet Torque Converter – Unmatched Holding Power

This rebuild kit comes with SunCoast’s Category 1 Triple-Disc Billet Torque Converter, a huge upgrade over the factory unit. Featuring a 2,000 RPM stall speed, carbon graphite clutch material, and a CNC-machined forged billet apply piston, this converter is designed to eliminate deflection, improve torque transfer, and extend clutch life. Whether you're launching off the line or towing a heavy load, this converter provides strong, positive engagement while maintaining efficient power delivery. When paired with the billet one-piece input shaft, made from 300 maraging steel for extreme strength, this combination ensures your 48RE can handle high torque without failure.
