Installation Notes

Skill Level: Advanced. A 4-inch coil-over lift with rear leaf spring replacement on the GMT900 platform requires a qualified suspension shop. Leaf spring replacement is a more involved rear suspension job than an axle block installation — plan accordingly. 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
• Leaf spring removal equipment per shop capability

Alignment: Full front-end alignment is mandatory after installation. Do not operate the vehicle on public roads before alignment is completed.

Break-In Period: Allow FOX 2.0 Performance Series shocks and new leaf springs to complete the manufacturer-recommended break-in period before aggressive off-road use. New leaf springs require a seating period before reaching rated ride height.

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 4 inches of lift on the GMT900 platform, typical fitment runs 33–35-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 187PSS is the standard-tier leaf spring rear system for the 2007–2013 GMT900 Silverado or Sierra 1500 2WD owner who wants 4 inches of front lift with FOX 2.0 Performance Series damping and a replacement rear spring assembly at the entry price point for this platform.

The decision between 187PSS and 187PES is the shock tier only — same platform, same 2WD requirement, same replacement leaf spring rear. FOX 2.0 Performance Series is a legitimate damping upgrade over factory shocks and handles daily driving, mild off-road, and light towing without issue. If you run this truck aggressively off-road, tow at or near capacity regularly, or want external reservoir thermal management, step up to SKU 187PES with FOX 2.5 PE. If the FOX 2.0 Performance Series meets your use case, 187PSS delivers the same 4-inch lift geometry and replacement leaf spring rear at a lower price point — and that is the correct call for a lot of GMT900 2WD owners.

The decision between 187PSS and 186PSS is the rear system — replacement leaf springs here versus a 5-inch axle block in 186PSS. Both run FOX 2.0 and are 2WD-specific. If you want a new spring rate and better articulation under load, 187PSS is the correct choice. If a block rear fits your use case and budget, 186PSS is the alternative.

This kit is for you if: You own a 2007–2013 Silverado or Sierra 1500 2WD, you want 4 inches of front lift with a replacement leaf spring rear, 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: Your truck is 4WD — order SKU 185PSS or SKU 186PES. You want FOX 2.5 PE damping — order SKU 187PES. You want a 5-inch axle block rear instead of leaf springs — order SKU 186PSS. You have a 2014 or newer Silverado/Sierra — different platform entirely, contact OFAS for the correct K2 SKU. You have a 2006 or earlier, or an HD model. Confirm your year and drivetrain before ordering — the kit is non-returnable once installed.

Common Questions

What is the difference between SKU 187PSS and SKU 187PES?
Both kits fit the 2007–2013 Silverado/Sierra 1500 2WD and deliver 4 inches of front lift with a replacement leaf spring rear. The only difference is the shock tier — 187PSS uses FOX 2.0 Performance Series and 187PES uses FOX 2.5 Performance Elite with external reservoir.
