1999-2006 Chevrolet Silverado / GMC Sierra 1500 2WD 7" Lift Kit + Upper Control Arms + Shocks | Trekline 1400LFT110077
This is the current Trekline high-lift package for the coil-spring-front GMT800 half-ton. SKC lists it simply as a 7-inch front lift kit; the included 5-inch rear blocks are the rear stance component rather than naming the product as a confusing “7/5” kit.
Why This GMT800 Kit Is More Complete
The front lift combines 4-inch lift spindles with fabricated coil spacers for nominal 3-inch additional front lift, then adds tubular upper control arms to help support the geometry at this height. It also includes tie-rod spacers, hub-plate spacers, a 2WD bump-stop adapter, front and rear shocks, and the rear block/U-bolt package.
