Product Description
4F50 AX4N AX4S AXOD AXODE Boost Valve Kit - O-RING STYLE
FITS ALL EXCEPT 3.0 LITER 12-VALVE ENGINES
Sonnax Part Number: 96201-01K
NO TOOLING REQUIRED
Vehicles with Ford AXOD, AXODE, AX4S or AX4N transmissions frequently have flare 1-2 and 2-3 upshifts, high pressure, harsh Reverse (300 psi), 2-1 downshift clunk, non-adjustable throttle pressure and clutch or band failure from poor line rise. This is caused by wear on the inside bore of the boost sleeve allowing TV/EPC and/or Reverse oil to either leak to exhaust or cross-leak. Sonnax offers boost valve kits for both 3.0 and 3.8 liter applications and sleeves with or without O-rings (factory style) to eliminate the above problems.
- Sleeves are made from high-quality aluminum to prevent wear
- Hardcoat anodized aluminum valve combats premature wear
- O-ring sleeves prevent leakage between the sleeve and valve body bore
- Available in two sizes: 96201-12K (O-ring style) with a small diameter boost valve of .475"; 96201-01K (O-ring style) and 96201-08K (factory style) with a small diameter boost valve of .491"
- Drop-in Zip Valve™ parts install quickly and easily
