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. You can expect a 10-15hp gain from this bolt-on. No valve cover or cylinder head modifications are necessary and stock pushrods can be re-used.
Arizona Speed and Marine long tube headers and SLP's 1.85 rocker arm package (53304) with SLP Springs, Titanium Retainers and Keepers $1429.99 (regular price - $1539.98)
