Head Diameter: 1.575 in. - Stem Diameter: .3136 in. - O/A : 4.923Manley Severe Duty Valves deliver the ultimate in strength, reliability, and high performance durability. Engineered for extreme gasoline engine temperatures, these valves are crafted from exclusive materials (XH 428 for exhaust and NK 844 for intake), offering unmatched tensile strength compared to competitive alloys. In fatigue testing at 40,000 psi and 1400F, Manley exhaust valves endured 100 million cycles, while competitors failed after just

the SB043 is cold formed to better resist torsional fatigue and retain its "memory" far longer than the hot-formed bars used by many competitors

3049-150 - 1978-1988 GM G-Body Rear Coilover Kit

Designed from CNC-laser cut

with weak materials that can lead to traction loss and poor handling

These lower A-arms are designed for use with coil-overs and do not have provision for the factory spring

NOTE: If you have a ZLE/1LE/PDQ version that has a bolt-on strut tower brace

Since the final viscosity after use of these fluids are similar
