KYB Suspension Strut and Coil Spring Assembly P/N:SR4078K
KYB Suspension Strut and Coil Spring Assembly P/N:SR4078K
$337.99

The KYB SR4078K front strut assembly for the 2004-2008 Ford F-150 and 2006-2008 Lincoln Mark LT replaces the strut, mount and coil spring at one front corner in one leveling assembly that raises the front of your 2WD truck.

  • Part of the KYB Truck-Plus line, built as a corner-specific front part number rather than a one-size-fits-all unit
  • Engineered to help vehicles with electronic safety systems such as ESC and ABS
  • Raises ride height approximately 2.5 inches while keeping designed performance on 2WD trucks
  • Built around a KYB Excel-G strut with a stronger steel outer shell and application specific precision designed damping valves
  • Winner of 2021 Best New Product
  • Application engineered KYB spring matched to the strut, designed to hold proper ride height longer and control weight without hurting ride quality

As a complete strut and coil spring assembly, it handles vehicle weight and sets ride height. A clunk over bumps, extra bounce after dips or nose dive under braking can mean a worn strut assembly, though worn ball joints or sway bar links can also clunk, so pin down the cause first.

It fits the 2004-2008 Ford F-150 without the Heavy Duty Suspension package and the 2006-2008 Lincoln Mark LT, both in 2WD form, and each truck takes two, one per front corner. This listing is one front strut assembly, and the opposite front corner is normally replaced at the same time.
