Contact OFAS at (469) 407-7538 to confirm which SKU is correct for your knuckle type, shock preference, and rear system before ordering.

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. Running a lifted truck without post-installation alignment causes accelerated tire wear, steering pull, and handling instability.

Knuckle Confirmation: Physically confirm or have a shop verify cast steel knuckles before ordering. Aluminum or stamped steel control arms require SKU 711PES. 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.

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 710PSS is the entry point into the 6-inch coil-over tier for the 2014–2018 K2 Silverado or Sierra 1500 4WD owner with cast steel knuckles. FOX 2.0 Performance Series front coil-overs, 5-inch rear axle block, FOX 2.0 rear shocks — a complete front-to-rear 6-inch system at the FOX 2.0 price point.

This kit is for you if: You own a 2014–2018 Silverado or Sierra 1500 4WD with confirmed cast steel knuckles, you want 6 inches of front lift with a matched 5-inch rear block, and the FOX 2.0 Performance Series is the correct shock tier for your budget and use case.

This kit is not for you if: You have aluminum or stamped steel control arms — order SKU 711PES. You want FOX 2.5 Performance Elite damping — order SKU 710PES for the 5-inch block or SKU 717PES for the leaf spring rear. You are running a 2013 or earlier GMT900, a 2019 or newer T1/T1XX, a 2WD, or a 2500HD/3500HD.

The only variable between 710PSS and 710PES is the shock tier — FOX 2.0 versus FOX 2.5 PE. If you tow heavily, wheel aggressively, or want external reservoir damping, step up to 710PES. If the FOX 2.0 Performance Series meets your use case, 710PSS delivers the same 6-inch front lift and 5-inch rear block at a lower price point. Confirm your knuckle type first — the kit is non-returnable once installed.

Common Questions

What is the difference between SKU 710PSS and SKU 710PES?
Both kits fit the 2014–2018 Silverado/Sierra 1500 4WD with cast steel knuckles and deliver 6 inches of front lift with a 5-inch rear axle block. The difference is the shock: 710PSS uses FOX 2.0 Performance Series and 710PES uses FOX 2.5 Performance Elite with external reservoir. If you tow, wheel hard, or want the higher damping tier, order 710PES. Call (469) 407-7538 to confirm which is correct for your use case.

What is the difference between SKU 710PSS and SKU 711PES?
Knuckle type. SKU 710PSS is for cast steel knuckles. SKU 711PES is for aluminum or stamped steel control arms. Confirm your knuckle type before ordering — ordering the wrong kit is a non-returnable error.

How do I know if my K2 Silverado/Sierra has cast steel knuckles?
Have a shop verify before ordering, or contact OFAS at (469) 407-7538. Do not estimate — the knuckle type determines which kit applies and the two kits are not interchangeable.

Does this kit include rear lift?
Yes. SKU 710PSS includes 5-inch rear axle blocks and FOX 2.0 Performance Series rear shocks. This is a complete front-to-rear system.

What size tires fit at 6-inch 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.

What warranty covers this kit?
BDS suspension components are covered by the BDS No-Fine-Print Warranty. FOX 2.0 Performance Series shocks carry a FOX 1-year limited warranty.
