Sonnax 700R4 4L60 Line Pressure Booster Kit for GM
- Large Ratio Boost Assembly
- Stronger Pressure Regulator Spring
Sonnax hydraulic line pressure booster kits contain stronger pressure regulator springs
and large ratio boost valves designed to work together to provide progressive pressure
increases as driving conditions become more demanding.
Sonnax pressure regulator springs are approximately 10% stronger than OE and more conservative
in impact than other aftermarket âkitâ springs. Large ratio boost valves provide higher pressure
incrementally and when it is needed the most.
The combination of these springs and valves in a Sonnax kit gives you the best of both worlds:
a modest pressure increase at the low end, with a high-end pressure that is equal to or
greater than that of other aftermarket âkitâ springs.
