Fits
- 2011-2019 Chevy Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD, 2WD and 4WD, with 1.5 to 3.5 in of front leveling lift (torsion keys or spacer) and a stock-height rear
Does not fit: stock height trucks (use the Stock Height kit), trucks with the rear raised 1.5 in or more (use the 1.5-3.5 in Lift kit), trucks with a 4 in or taller lift kit
Why this kit
The most common GM HD setup: torsion keys or a spacer bringing the nose up 1.5 to 2.5 in, rear left alone. The factory-length front shock runs out of droop at that height and tops out over dips. This kit pairs two 985-24-189 fronts sized for 1.5 to 3.5 in of front lift with two 980-24-664 rears for the untouched rear, so both ends get the FOX 2.0 IFP monotube at the correct length. Aluminum body, internal floating piston keeping the nitrogen off the oil, race-derived high-flow piston with application-specific valving.

Questions
Cranked torsion bars count as leveled?
Yes. Whether the lift came from keys, a spacer, or cranking the factory bars, measure the front fender height against stock. Anywhere from 1.5 to 3.5 in above stock is this front. Under 1.5 in, use the Stock Height kit.
My rear has blocks too. Which set?
If the rear was raised 1.5 in or more, use the 1.5-3.5 in Lift kit, which swaps the rear to the longer 985-24-190.
How long does installation take?
Rears are 20 to 30 minutes per side with hand tools. Fronts on the GM independent front suspension bolt to the lower control arm and the frame, about 30 to 45 minutes per side, no spring compressor needed.
What is the warranty?
FOX covers 2.0 and 2.5 Performance Series IFP shocks purchased after 3/30/2025 with a limited lifetime warranty against defects, to the original retail owner through the original place of purchase. Keep your Hannah Suspension order confirmation.
