Boost Valve & Sleeve Kit - GM 350C/350
Price: $110.18
Part Number: TAT-35754-01K-SX
The OEM boost valve sleeve wears out from the reciprocation of the steel valve within the aluminum sleeve. Wear in the reverse boost sleeve results in low line pressure, soft 1-2 and 2-3 shifts and/or reverse engagement or shudder. Sonnax now offers 35754-01K, a high performance boost valve and sleeve replacement. This new high performance boost valve and sleeve incorporates a larger boost ratio, which increases line pressure and provides firmer shifts. It is also recommended for street/strip performance vehicles.

Redesigned sleeve prevents sticking

Larger boost ratio

No machining required
