The Carli Suspension Pintop System delivers a true premium ride upgrade with Carli-blueprinted King 2.5” shocks on all four corners—purpose-built for heavy-duty trucks. Unlike off-the-shelf shock packages, Carli designs a proprietary piston that sets ideal base flow rates for HD platforms, then hand-tunes each shock for the only performance metric that matters: unmatched, seat-of-the-pants comfort and control on and off road.

Every shock is finished with solid 17-4 stainless steel shafts, machined and polished in-house. This eliminates the weaknesses of standard coated shafts—no coating to wear off, no corrosion issues, and no brittle failures. Even if a chip occurs, a quick polish with emery cloth keeps the shaft and seals protected, ensuring long-term durability.

Carli pairs the system with King’s extreme-temperature oil rated to -55°F, maintaining consistent damping in harsh conditions. Because all King shocks use a plated steel body, Carli recommends a simple 3M protective wrap for those who frequently run in salted or wet environments.

Bottom line: The Carli Pintop System is engineered for customers who want the best-riding, most durable King 2.5 shock package available—precision-tuned performance, long-life materials, and proven reliability in real-world abuse.
