We are running a GP for the SLP 1.85 rocker arm packages. They are designed for gen III engines (LS1, LS6, Truck 4.8,5.3,6.0). SLP's exclusive design is based on the stock rocker and is built by the OEM manufacturer using the same high quality materials and processes. Versus the stock 1.7:1 ratio rocker, SLP's 1.85:1 ratio rocker will result in horsepower and torque gains by increasing lift by approximately 10% and forcing the valves to accelerate faster during opening and closing. SLP's rocker was designed as a bolt-on replacement for stock. No valve cover or cylinder head modifications are necessary and stock pushrods can be re-used. Depending on model application, optional SLP valve springs may be required. The rockers are offered in 4 kits to suit your particular needs. Refer to the application chart for details. SLP highly recommends our tool set (PN 53306) for proper installation. Refer to SLP's application chart (stock camshafts only) to select the kit you need.
