Ring Gear Stabilizer Kit

Part No. 28510-S2

  • Ring Gear Stabilizer Race
  • Bearing Buttons (5)

For Sonnax 1.69 and 1.80 ratio bolt-together carriers only.

Vibration at high speeds and broken Reverse friction plates are common problems in GM Powerglide racing transmissions. These issues occur when the poorly supported planetary ring gear moves off the transmission center line, oscillating out of control. Ring gear oscillation can also cause increased drag of the Reverse clutches and stress the short pinion gears. Sonnax ring gear stabilizer kit 28510-S2 bolts up to Sonnax 1.69 and 1.80 ratio bolt-together carriers to support the ring gear—keeping it on center, reducing drag, and preventing vibration, wear and short pinion gear stress.

NOTE:

The following tools are required to install Sonnax ring gear stabilizer kit:

  • 1/8" Drill bit
  • 1/4" Drill bit

  • Patent Pending
