Super Hold Servo Kit
Part No. K65703Sonnax super hold servo kit K65703 for GM 200, 200-4R, 200C units features a 17% greater apply area than the Grand National servo. Its pin is longer than the longest OE pin, allowing for a full range of adjustment. The optional parts include a shim, spring and spacer which, when combined with OE springs, result in a variety of shift tuning capabilities. Altogether, the level of customization in this kit makes it ideal for high-performance street applications as well as all-out racing.
Overall sealing characteristics have been improved throughout the servo, which features an O-ring to seal the piston to pin. This O-ring prevents cross leakage between the apply and release side of the piston, ensuring all apply pressure gets to the piston for solid shifts.
- 17% Greater apply area than Grand National servo
- Extra-long servo pin and optional parts for highly tunable shift feel
- Outstanding sealing characteristics
- Made from 6061 billet aluminum for improved strength

Line Pressure Booster Kit
Part No. 700R4-LB1Line pressure booster kit 700R4-LB1 fits GM 4L60 (700-R4) and 200-4R transmissions. Sonnax hydraulic line pressure booster kits contain stronger pressure regulator springs and large ratio boost valves designed to work together to provide progressive pressure increases as driving conditions become more demanding.
Our pressure regulator springs are approximately 10% stronger than OE and more conservative in impact than other aftermarket kit springs. Large ratio boost valves provide higher pressure incrementally and when it is needed the most. The combination of these springs and valves in a Sonnax kit gives you the best of both worlds: a modest pressure increase at the low end, with a high-end pressure that is equal to or greater than that of other aftermarket kit springs.
- Achieve shorter shifts and increased torque capacity without creating low-speed harshness
- Improved band and clutch holding capacity for increased durability
- Progressive pressure increase as driving conditions become more demanding
- All the benefits of increased line pressure without overloading the pump at idle
- Simple and affordable drop-in solution with no special tools or reaming required
- O-Rings (2)
- Pressure Regulator Spring
- Large Ratio Boost Assembly
