PRW LS OEM upgrade rocker arms are designed as drop-in systems to replace the OEM valvetrain. These 1.7 ratio x 8mm rocker arms install easily on your LS cylinder heads without any necessary modifications. They include drawn cup needle roller trunnion bearings which are far superior to the factory oem cageless needle bearings which tend to fail in high rpm or with higher valve spring pressures. PRWs oem upgrade rocker arms are a great choice to add strength and performance to your valvetrain.
