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.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003eOur pressure regulator springs are approximately 10% stronger than OE and more conservative in impact than other aftermarket kit 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 kit springs.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli style=\"text-align: left;\"\u003eAchieve shorter shifts and increased torque capacity without creating low-speed harshness\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eImproved band and clutch holding capacity for increased durability\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eProgressive pressure increase as driving conditions become more demanding\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eAll the benefits of increased line pressure without overloading the pump at idle\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eDrop-in Zip Valve\u003csup\u003e™\u003c\/sup\u003e parts install quickly and easily\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"text-align: left;\" class=\"part-accordion cb spaced-vertical\"\u003e\n\u003cdiv id=\"notes\"\u003e\n\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cstrong\u003e\u003clabel for=\"notes-panel\"\u003eNote\u003c\/label\u003e\u003c\/strong\u003e\u003c\/span\u003e\n\u003cdiv class=\"accordion-content\"\u003e\n\u003cp\u003e\u003cstrong\u003eThis Kit Replaces early-style boost valve\u003c\/strong\u003e with \"long\" 1.907\" sleeve.
