Description: Sonnax 2nd gear super hold servo kit is the largest and most leak free servo available for Dodge Chrysler 46RH 46RE 47RH 47RE 48RE and A727 units. It reduces the need for agressive lever ratios, excessively high line pressure and other radical modifications to achieve firmer shifts. Sonnax's exclusive servo design features rubber and PTFE seals that enhance positive sealing and prevent case wear. The overall result is more holding force in 2nd, firmer 1-2 shifts and 2-3 shifts that become firmer under load.
- Easy to install servo improves 1-2 & 2-3 shifts
- 16% more apply area for more band holding power
- 15% less leakage than other designs
- Anodized Aluminum for increased durability
- Aluminum Piston

Description: OE plastic accumulators in listed Chrysler units are prone to breaking and have poor sealing qualities. Metal rings offered with aftermarket accumulators also have sealing issues. The improved design and material of Sonnax accumulator piston kit eliminates cross-leaks between circuits.
- Rubber D-rings for superior sealing
- PTFE guide seal prevents case wear from piston contact
- Anodized billet aluminum piston for improved durability
