450-43LE
Boost Valve Kit
Part No. 94987-09K
This kit fits '98-later models: Isuzu NPR, GMC Forward Tiltmaster, Chevrolet Forward, Nissan UD and Mitsubishi Fuso Trucks.
The boost valve assembly is designed to increase line pressure in Drive and Reverse. When the AW 450-43LE sleeve is worn on the inside or loose within the valve body, boost or EPC fluids can leak to exhaust or cross leak and increase forces on the valve. Leakage to exhaust reduces line rise, while the cross leaks can result in broken clutch drums or cases. Sonnax main boost valve and sleeve kit 94987-09K has upgraded materials to prevent wear and restore proper hydraulic control.
- Sleeve is manufactured from highly wear-resistant billet aluminum
- Aluminum valve has been hard-coat anodized to reduce wear
- Restores proper hydraulic sealing and OE pressure control
- No special tools required
