Front Brake Lines for 1979-1987 GM 4WD at 3-4 Inches of Lift

About this part

Front Brake Lines, fitment-checked

The later light-duty GM pair, picking up the 1979-1986 K10 and K20, the K5 Blazer, and Blazer bodies through 1991. Earlier trucks take a separate part number. Same 7200 GVWR or less rating, same 3-4 in. lift band.

Chevrolet changed the front end enough in 1979 that the brake lines are not interchangeable across that year, which is why this part number exists alongside the earlier one. Coverage is the K10 and K20 from 1979-1986, the K5 Blazer over the same years, the V10 and the Blazer body through 1991, plus the GMC equivalents. The rating is 7200 GVWR or less and the lift band is 3-4 in. Sold as a pair for the front axle. If your truck is a three-quarter ton or heavier, a different part number applies.
