Installation Notes
Skill Level: Advanced. A 6-inch coil-over lift with 5-inch rear axle block on the K2 platform requires a qualified suspension shop. This is not a bolt-on leveling kit. Do not attempt DIY installation.
Required Tools:
- Full hydraulic lift rated for truck weight
- Coil-over compression tool
- Torque wrench
- Full socket and wrench set
Alignment: Full front-end alignment is mandatory after installation. Do not operate the vehicle on public roads before alignment is completed.
Control Arm Confirmation: Physically confirm or have a shop verify aluminum or stamped steel control arms before ordering. Cast steel knuckles require SKU 710PES or SKU 717PES. This is a hard stop — the wrong kit will not install correctly.
Rear Axle Block Installation: 5-inch axle blocks must be installed per BDS specifications. Confirm U-bolt torque specs and axle centering after installation. Improperly centered axle blocks cause driveline vibration and premature U-joint wear.
Reservoir Routing: Follow BDS and FOX installation instructions for FOX 2.5 PE reservoir placement. Avoid pinch points and heat sources. Incorrect reservoir routing causes premature shock failure.
Extended Brake Lines: Verify whether extended brake lines are required for your specific configuration at time of installation.
Torque Specs: Follow BDS-specified torque values included in the installation instructions. Do not substitute generic torque values on a lifted platform.
Tire Fitment: At 6 inches of lift on the K2 platform, typical fitment runs 35–37-inch tires depending on wheel offset and backspacing. Confirm maximum tire diameter and wheel specifications with your wheel and tire supplier before ordering.
The Obsidian Take
SKU 711PES is the premium-tier 6-inch coil-over system for the 2014–2018 K2 Silverado or Sierra 1500 4WD owner with aluminum or stamped steel control arms. FOX 2.5 Performance Elite coil-overs with external reservoir up front, 5-inch rear axle block, FOX PE rear shocks — a complete front-to-rear system at the top of the FOX coil-over tier on this platform.
This kit is for you if: You own a 2014–2018 Silverado or Sierra 1500 4WD with confirmed aluminum or stamped steel control arms, you want 6 inches of front lift with a matched 5-inch rear block, and you want FOX 2.5 Performance Elite damping with external reservoir — not the FOX 2.0 entry tier.
This kit is not for you if: You have cast steel knuckles — order SKU 710PES for the 5-inch block or SKU 717PES for the leaf spring rear. You want FOX 2.0 Performance Series instead of FOX 2.5 PE — order SKU 710PSS. You are running a 2013 or earlier GMT900, a 2019 or newer T1/T1XX, a 2WD, or a 2500HD/3500HD.
The difference between 711PES and 710PES is the control arm type — aluminum or stamped steel here versus cast steel knuckles in 710PES. Both run FOX 2.5 PE and a 5-inch rear block. The control arm type is the only fitment variable between these two SKUs — confirm it before ordering. If you want leaf springs at the rear instead of the 5-inch block, 717PES is the cast steel knuckle alternative. There is no aluminum/stamped steel leaf spring variant in this lineup — 711PES is the only FOX 2.5 PE option for your control arm type. The kit is non-returnable once installed.
Common Questions
What is the difference between SKU 711PES and SKU 710PES?
Both kits deliver 6 inches of front lift with FOX 2.5 Performance Elite coil-overs and a 5-inch rear axle block. The difference is control arm type — 711PES is for aluminum or stamped steel control arms and 710PES is for cast steel knuckles. Confirm your control arm type before ordering. Call (469) 407-7538) if you need help identifying which you have.
What is the difference between SKU 711PES and SKU 710PSS?
Two variables: control arm type and shock tier. SKU 710PSS is for cast steel knuckles with FOX 2.0 Performance Series shocks. SKU 711PES is for aluminum or stamped steel control arms with FOX 2.5 Performance Elite. These kits are not interchangeable on either variable.
Is there a leaf spring rear option for aluminum or stamped steel control arms?
No. The leaf spring rear variant — SKU 717PES — is for cast steel knuckles only. SKU 711PES with the 5-inch axle block is the only FOX 2.5 PE option for aluminum or stamped steel control arms on this platform.
How do I confirm my control arm type?

Yes. SKU 711PES includes 5-inch rear axle blocks and FOX Performance Elite rear shocks. This is a complete front-to-rear system.
What size tires fit at 6-inch lift on the K2 platform?
