With a .625" maximum lift, these Beehive Valve Springs were designed for hydraulic Roller cams in LS1, LS2 and LS6 engines. COMP Cams Beehive Valve Springs deliver increased valve train stability and a much lighter valve train. This is achieved with less spring pressure for better valve control and reduced weight of both the spring and retainer. The unique Beehive shape handles valve train stress more efficiently to eliminate damaging harmonics and increases high RPM horsepower and durability. The oval/multi-arc wire shape places the maximum area of the wire at the point of highest stress to handle valve train stress more efficiently and allow better heat dissipation for longer life. Because of the unique Beehive design, the valve train can handle more RPM and more aggressive Camshaft profiles.Part #ODIDSeat LoadOpen LoadCoil BindRate (Lbs./In.)Titanium RetainerSteel RetainerCup SeatShims269181.0751.310.650.885125 @ 1.800367 @ 1.1501.140372762, 772, 788761, 774, 783, 787, 79547054753This Part Fits: Year Make Model Submodel 2004-2007 Cadillac CTS V 1998-2002 Chevrolet Camaro Z28 1998-2002 Chevrolet Camaro Z28 SS 2008 Chevrolet Corvette 427 Limited Edition Z06 2003 Chevrolet Corvette 50th Anniversary Edition 2003 Chevrolet Corvette 50th Anniversary Edition Pace Car 1997-2007,2009-2011 Chevrolet Corvette Base 2010-2011 Chevrolet Corvette Grand Sport 1998 Chevrolet Corvette Indianapolis 500 Pace Car 2001-2004,2007-2011 Chevrolet Corvette Z06 2011 Chevrolet Corvette Z06 Carbon 2009-2011 Chevrolet Corvette ZR1 2006-2007 Chevrolet Impala SS 2006-2007 Chevrolet Monte Carlo SS 2005-2006 Chevrolet SSR Base 2006 Chevrolet Trailblazer SS 2003 Ford E-150 Base 2003 Ford E-150 Club Wagon Chateau 2003 Ford E-150 Club Wagon XL 2003 Ford E-150 Club Wagon XLT 1997-2002 Ford E-150 Econoline Base 1997-2000 Ford E-150 Econoline XL 1997-2002 Ford E-150 Econoline Club Wagon Chateau 1997-2000 Ford E-150 Econoline Club Wagon Custom 2001-2002 Ford E-150 Econoline Club Wagon XL 1997-2002 Ford E-150 Econoline Club Wagon XLT 2003 Ford E-250 Base 1997-2002 Ford E-250 Econoline Base 1997-2000 Ford E-250 Econoline XL 1997-2000 Ford F-150 Base 2005-2007 Ford F-150 STX 1997-2003,2005-2007 Ford F-150 XL 1997-2003,2005-2007 Ford F-150 XLT 2004 Ford F-150 Heritage XL 2004 Ford F-150 Heritage XLT 2004-2007 Ford Freestar Limited 2004-2007 Ford Freestar SEL 1994-2004 Ford Mustang Base 1989-1995 Ford Taurus GL 1991-1992 Ford Taurus L 1989-1995 Ford Taurus LX 1995 Ford Taurus SE 1989-1992 Ford Thunderbird Base 1989-1997 Ford Thunderbird LX 1989-1995 Ford Thunderbird Super Coupe 1995-2003 Ford Windstar Base 1995-1998 Ford Windstar GL 1998,2000-2003 Ford Windstar Limited 1995-2003 Ford Windstar LX 1999-2003 Ford Windstar SE 2001-2002 Ford Windstar SE Sport 1999-2003 Ford Windstar SEL 1989-1994 Lincoln Continental Base 1991-1994 Lincoln Continental Executive 1989-1994 Lincoln Continental Signature 1989-1992 Mercury Cougar LS 1989-1990,1993-1997 Mercury Cougar XR-7 2004 Mercury Monterey Base 2005 Mercury Monterey Convenience 2006-2007 Mercury Monterey Luxury 2004-2005 Mercury Monterey Premier 1989-1995 Mercury Sable GS 1989-1995 Mercury Sable LS 1998-2002 Pontiac Firebird Formula 1998-2002 Pontiac Firebird Trans Am 2005-2007 Pontiac Grand Prix GXP 2004-2006 Pontiac GTO Base
