1973-1987 Chevrolet C10 2WD 3"/5" Drop Spindle Kit - 1.00" Rotors
For a classic squarebody stance without cutting springs, this kit combines heavy-duty lowering spindles with a five-inch rear flip package matched to the 1973-1987 C10 chassis.
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.
Kit Contents:
- 3-inch heavy-duty front drop spindles (pair)
- 5-inch rear axle flip kit
Vehicle Fitment:
- 1973-1987 Chevrolet C10 2WD
Important Fitment & Installation Notes:
- Shocks are not included; verify available shock travel before road use.
- Trekline identifies this 3/5 combination as not requiring a C-notch under normal installation conditions; still verify axle-to-frame clearance on the finished truck.
- 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.
