The traditional metal tip on standard rockers literally drags across the valve tip as the rocker opens and closes causing high side loading on the valve. Other Yella Terra rocker components such as the trunnions, posi locks and bearings greatly enhance valve train durability in performance applications. Pressed steel rocker arms, in high performance applications, are prone to failure, A high rate of fulcrum wear, flexing, cracking, splitting and breakage are common problems that will result in power loss or possible piston failure due to detonation of the incoming air/fuel charge. The rocker arms used on Yella Terra and Street Terra roller rockers are infinitely stronger than standard pressed steel arms providing the best in resistance to bending and breakage under high spring pressures at high RPM's.
Why choose Yella Terra Full Roller Rockers? They will produce more power with less valve float and include pushrods which are 10% lighter than stock. These roller rockers are the lightest on the market with each rocker arm weighing only 6 ounces. 1995-2006 other applications with 3800 Series II or Series III engine ***.1995-2003 Regal with 3800 Series II engine.1995-2003 Park Avenue with 3800 Series II engine.1996-1996 Oldsmobile 98 with 3800 Series II engine.1995-1999 Oldsmobile 88 with 3800 Series II engine.1998-2005 Monte Carlo with 3800 Series II engine.1998-2000 Lumina with 3800 Series II engine.1996-2003 LeSabre with 3800 Series II engine.1998-1999 Intrigue with 3800 Series II engine.2000-2005 Impala with 3800 Series II engine.1997-2006 Grand Prix with 3800 Series II or Series III engine.1996-2002 Firebird with 3800 Series II engine.1996-2002 Camaro with 3800 Series II engine.1995-2003 Bonneville with 3800 Series II engine.
