Proline’s newest 1:5 scale rubber rollers are called the LockDowns. Molded in the durable XTR compound, these race tires feature a more open tread pattern than the Blockades as well as a connected side tread. This combination makes these tires perfect in loose-track conditions as well as slightly reducing the sidewall grip to prevent your truck from catching a rut and flipping over.
The inside construction of the LockDowns contain detailed webbing that heavily supports the tire carcass and prevents excessive tire expansion.
Inner foams are not included but works with either HPI’s 5T rear foam (#4818) or Losi 5IVE-T’s front/rear foams (#LOSB7241).
