Sonnax Industries Tramsmission LINE PRESS BOOSTER KIT- EARLY Line Pr

Line pressure booster kit 4L60E-LB1 fits early-style GM 4L60-E, 4L65-E and 4L70-E pumps. 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. Our 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. Achieve shorter shifts and increased torque capacity without creating low-speed harshness Improved band and clutch holding capacity for increased durability Progressive pressure increase as driving conditions become more demanding All the benefits of increased line pressure without overloading the pump at idle Drop-in Zip Valve parts install quickly and easily Learn More About Zip Valve Drop-In Repairs
