This aftermarket 4 piece inner & outer window sweep weatherstrip set is brand new to the market! The set includes both the outer and inner sweeps for both doors. These are the strips that attach to the doors and "sweep" the windows as they go up and down. Their function is to keep dirt and water out of the inside of the door, preventing rust.


  • Comes as a 4 Piece Set
    • Fits both LH (Driver Side) & RH (Passenger Side) INNER & OUTER
  • Commonly called "Inner Belt Weatherstrip" & "Outer Belt Weatherstrip"
  • Fits and sweeps against the inside & outside part of the door glass
  • Direct replacements for models WITHOUT Outer Reveal Moldings
    • Correct for models with Black Bead on Sweeps
  • Fits 2 Door Coupe Models only

NOTE: These window sweeps fits models with the Black Bead on the outer window sweeps. They do NOT fit models with a separate 1 inch wide window sill moldings (Reveal Moldings).

If your window sweeps are cracked and allowing the elements into your door, then these parts are for you.
