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.

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.

Break-In Period: Allow FOX 2.5 PE 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 187PES is the premium-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 2.5 Performance Elite damping and a replacement rear spring assembly — not a spacer lift, not a block rear, not the FOX 2.0 entry tier.

The decision between 187PES and 187PSS is the shock tier only — same platform, same 2WD requirement, same replacement leaf spring rear. FOX 2.5 PE delivers a larger piston diameter, external reservoir thermal management, and a more refined damping curve than the FOX 2.0 Performance Series. If you run this truck hard, want the top damping tier available for this system, or plan on regular off-road use after the lift — 187PES is the correct choice. If the FOX 2.0 Performance Series meets your use case and budget, 187PSS delivers the same lift geometry at a lower price point.

The decision between 187PES and 186PES is drivetrain. Both run FOX 2.5 PE with replacement leaf springs. 187PES is for 2WD. 186PES is for 4WD. Confirm your drivetrain before ordering — this is a non-returnable error if you get it wrong.

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 you want FOX 2.5 Performance Elite damping with external reservoir — the top tier available for this platform and configuration.

This kit is not for you if: Your truck is 4WD — order SKU 186PES or SKU 185PSS. You want FOX 2.0 instead of FOX 2.5 PE — order SKU 187PSS. 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.
