1973-1987 Chevrolet C10 2WD 3"/6" Drop Spindle Kit - 1.00" Rotors
This 3/6 Chevrolet C10 package pairs heavy-duty drop spindles with a six-inch rear axle flip for the deeper squarebody stance many street-truck builds are after.
This is the 1.00-inch rotor spindle version. Measure the front rotor thickness before ordering; the 1.00-inch and 1.25-inch spindle versions are different applications and should not be substituted for one another. This SKU focuses on the hard lowering components and leaves the shock choice separate, which can be useful when the truck already has compatible dampers or the builder wants to choose a specific shock package. Because the rear is lowered six inches or more, frame clearance must be addressed with a C-notch before the truck is driven.
Kit Contents:
- 3-inch heavy-duty front drop spindles (pair)
- 6-inch rear axle flip kit
Vehicle Fitment:
- 1973-1987 Chevrolet C10 2WD
Important Fitment & Installation Notes:
- Shocks are not included. Trekline specifies shorter rear shocks for this 3/6 spindle-and-flip combination.
- A rear C-notch is required for adequate axle-to-frame clearance at this drop and is not included with this SKU.
- Rotor check: this SKU is for 1.00-inch-thick front rotors. Measure before ordering.
- Trekline notes that some 15-inch wheel combinations may require lower-control-arm grinding for adequate spindle/wheel clearance. Check the complete wheel, tire and suspension package during installation.
- Perform a professional alignment after installation and verify steering clearance, brake-hose routing, bump-stop clearance, shock travel and fastener torque before regular road use.
- Lowering amounts are referenced from stock OEM ride height; worn springs, prior suspension modifications or existing sag can change the measured result.
