Dropped spindles will not only enhance the rake of your Tri-Five Chevy, they will also improve handling due to the lower roll center. These spindles are designed like the original only they have 2” of drop built in. Plus, dropped spindles maintain factory steering & suspension geometry so original steering arms can be used.

The optional disc brake kit features 10 ½” GM vented cast iron rotors and 1969-77 single piston calipers. Spindles sold separately. Brake kit sold separately.

Note: These spindles cannot be used with stock drums or brake conversions for stock spindles.
