    11506 is rated 4.0 out of 5 by 2.
    Rated 4 out of 5 by from Good quality! I bought these a month ago and just got them installed onto my 88 K5 Blazer. Make sure after you install them to buy flame resistant paint and spray them to prevent rusting or chipping.

    Rated 4 out of 5 by from easy instal Easy installation the only issue I had was the gaskets were messed up during shipping and it would be wise to invest in a spacer for the power steering bracket great product sounds good
