    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.
    Date published: 2017-05-05
    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

    I have an 81' K20 Scottsdale Pickup with the NP208 t-case. Will these have any clearance issues with the frame or starter or front driveshaft at all?

    Asked by: Chace
    No, these are made to fit your truck and we would not expect any clearance issues.
