UMI Performance AB7350-1 Shock & Spring Lowering Kit | 1967 GM A-Body | Double Adjustable Viking Coilovers | 350lb Front Spring | 1" Rear Drop

The UMI Performance AB7350-1 is a complete front and rear shock and spring lowering kit engineered for the 1967 GM A-Body platform. This bolt-in package pairs a hybrid front coilover spring system with four Viking double adjustable shocks and your choice of 1-inch rear lowering springs — delivering a tunable, performance-ready suspension upgrade without welding or a spring compressor.

Kit Contents:

• (2) Front coilover shocks — Viking double adjustable
• (2) Front springs — 350lb spring rate (ideal for small block cruise or drag race applications with weight reduction)
• (2) Rear double adjustable Viking shocks
• (2) Rear lowering springs — 1" rear drop

Front Spring Rate Options (order separately):

• 250lb — 11" tall drag race spring; serious weight reduction required
• 350lb — Small block cruise or drag race with lightening required
• 450lb — Small block street/cruise; all big block drag race applications
• 550lb — Small block performance handling; all big blocks except drag race

Viking Double Adjustable Shock Features:

• 19 independent compression and 19 rebound settings (361 total tuning combinations)
• Tune for street, strip, or corner carving at the turn of a knob — no tools required
• Hand built in Lakeville, Minnesota
• Premium USA-made springs — shot peened and coated for long-term durability
• Rebuildable construction for extended service life

Lowering & Handling Benefits:

• 0–3" adjustable front drop via the hybrid coilover spring system
• 1" rear drop with included rear springs (2" option available)
• Lower center of gravity improves overall handling performance
• Places the upper A-arm in a more favorable geometry angle
• Easy front height adjustment — spanner wrench and Torrington (thrust) bearing kit available separately and strongly recommended

Suggested Baseline Shock Settings:

• All-around street: 6C / 8R
• Corner carving: 10C / 12R
• Strip (front / rear): 6C, 2R front — 6C, 6R rear

Spanner Wrench & Thrust Bearing Kit (Optional but Recommended): The spanner wrench adjusts ride height while the shock remains mounted. The thrust bearing kit installs between the spring and spring seat, allowing the seat to rotate on a bearing for smoother, easier height adjustments. UMI does not recommend making height adjustments without the thrust bearing kit installed.

This is a true bolt-in kit — no welding required and no spring compressor needed for front installation. Viking coilovers are compatible with UMI's geometry-corrected lower A-arm or the factory lower A-arm.
