4L60E 4L65E 4L70E Sonnax Line Pressure Booster Kit Late Style 2006 UP 4L60E-LB2

Sonnax 4L60E 4L65E 4L70E Line Pressure Booster Kit GM for Late Style Pump 2006 & UP This kit includes Large Ratio Boost Assembly - short Stronger Pressure Regulator Spring 2 O-Rings 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 “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. Kits available for either early (long) or late (short) style boost valves Achiev
