1988-1998 Chevrolet/GMC C2500 2WD 6-Lug 6" Lift Kit with 2" Rear Leveling Block - 1.25" Rotors | Trekline 1375LFT110039
Built for the less-common six-lug 1988-1998 C2500 2WD, this Trekline package gives the truck 6 inches of advertised front lift. SKC names the kit by that front height; the 2-inch rear block is listed separately as the rear stance/leveling component rather than calling this a confusing “6/2” kit.
How This 6" C2500 Kit Gets Its Height
The 6-inch setup combines the 4-inch lift spindle with a 2-inch front coil spacer, creating a taller OBS stance while keeping the front suspension coil-spring based. The 2-inch rear block adds useful rear clearance while still allowing the front lift to lead the stance. This version leaves shocks out for builders who already have compatible extended-length dampers or want to choose their own shock package.
What Is Included
- Left and right 4-inch front lift spindles
- Pair of fabricated steel front coil spacers for nominal 2-inch additional front lift
- Pair of 2-inch rear lift / leveling blocks
- 4 Grade 8 rear U-bolts, 8 nuts and 8 washers
- Shocks are not included in this version

Critical Fitment & Installation Notes
- Six-lug C2500 only. Does not fit eight-lug C2500/C3500, 4WD, Suburban or SUV applications.
- Requires approximately 1.25-inch-thick front brake rotors. Measure before ordering; these spindle kits do not fit the 1-inch light-duty brake package.
- If the truck has rear overload springs, confirm U-bolt requirements before ordering.
- Factory alignment knockouts must be removed to fine-tune alignment after installation.
- Aftermarket upper control arms are recommended because this package uses 2-3 inches of front coil-spacer lift.
- Spindle-equipped kits require 16-inch or larger wheels with no more than 4.5 inches of backspacing. Front track width increases approximately 1 inch per side.
- Lift height is nominal; spring age, accessories, payload and existing suspension changes can affect final stance.
- Professional installation and a complete wheel alignment are recommended.
- Verify steering, brake-hose, ABS-wire, shock, tire, wheel and driveline clearance through full travel.
