Sonnax 2nd gear super hold servo kit 77911-03K for GM 4L60 (700-R4), 4L60-E, 4L65-E and 4L70-E units delivers 18% more apply area than the “Corvette” servo (largest OE). It's the perfect choice for performance applications when a larger-than-OE servo is desired, and its unique design avoids the timing flaws and excessive shock loads found in other aftermarket servos. Combine this servo kit with Sonnax 4th gear servo 77767K for unmatched holding power and shift performance that's an easy in-vehicle install.
