Front Brake Lines for GM 3/4 and 1-Ton 4WD at 3-4 Inches

About this part

Front Brake Lines, fitment-checked

This is the heavy-duty branch of the range: trucks rated 8600 GVWR or greater, which is the three-quarter ton and one-ton chassis rather than the half-ton. Coverage is the 1979-1986 K20, K30 and the K10, K20 and V-series Suburbans, at 3-4 in. of lift.

GVWR is what separates this part from the light-duty pairs, and the threshold is explicit: 8600 or greater. That puts it on the K20 and K30 from 1979-1986, the K10 and K20 Suburbans over the same span, the V10 and V20 Suburbans through 1988, and the GMC equivalents — nineteen applications in all. The lift band is the shallower one at 3-4 in. Check the door-jamb sticker rather than the badge, because a three-quarter-ton truck can sit either side of the line depending on how it was optioned. Sold as a pair.
