Product Details

The Dexter Marine Products 006-257-00 is a zinc-plated replacement locknut designed specifically for DexMarine DX8.0 and Model 60 surge brake actuators. This locknut is a critical component in the lever-lock coupler assembly that allows for proper adjustment and secure operation of the brake actuator.

Key Features:

  • Zinc-plated finish for corrosion resistance in marine environments
  • Compatible with DexMarine DX8.0 and Model 60 brake actuators
  • Used to adjust coupler fit for different hitch ball sizes (2", 1-7/8", or 50mm)
  • Located underneath the ball latch in the coupler assembly
  • Works with locking plate to prevent vibration loosening
  • Genuine Dexter replacement part (formerly Dico/Titan)

This locknut is essential for maintaining proper coupler tension and ensuring safe trailer operation. The zinc plating provides excellent protection against corrosion from salt water and harsh marine conditions. When replacing, ensure the locknut is properly aligned with the flanges of the lock plate to prevent loosening during use.

Easy to order, great price and fast shipping. Great first buying experience.

Very easy so far.

Fine

Had what I needed at a reasonable price

I received the bar and it looks to be very high-quality. However, this bar says it fits a 2003 through 2013 dodge ram 25 and 3500 series trucks. However, from 2003 to 2007-1/2. This truck comes with 1/2' (14mm) bolts. This bar only comes with the 14 mm and the upgraded 5/8' Hardware for the top joint. The lower joint connecting to the Axle only has the 5/8 hole and does not come with a reducing kit nor does it come with an upgraded 5/8' bolt, which would at least allow you to drill out the lower Mounting holes to mount this bar. As a result, you cannot use the original bolt and you have to go to Supply store to find the correct size bolt to allow you to mount this track bar. Highly inconvenient for the customer, especially when there is no mention of this in the description for the part. At the bare minimum, this track bar should've came with the second 5/8' bolt With the kit.

Good
