This Kit Is Ready To Install And Is Super Heavy Duty And Features;
Sonnax super hold servo kit K65703 for GM 200-4R 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.

This is the largest on the market. The Sonnax servo kit includes many tune-able features. The Sonnax servo pin is longer than the longest available OEM pin and can be shortened to precisely set pin engagement. A medium rate return spring is also included with the Sonnax kit and is interchangeable with OEM springs for further tuning. The Sonnax super size servo can be set-up for high performance street applications as well as for all-out racing by including or excluding springs, shims, and spacers included with the kit. The Sonnax design is a radical departure from the OEM design to improve strength and reduce material and machining time in order to provide a higher quality, more complete kit, at a lower cost to the customer. The sealing characteristics have been improved throughout the design and it features the addition of an o-ring seal at the intersection of the servo pin and the piston. This prevents any crossover leakage between the apply and un-apply sides and ensures all apply pressure gets to the piston for good solid shifts. These features result in the firmest 1-2 and 2-3 shifts and help to clean up the kick down response from 3-2.
