2600 Series Air Spring | 10″ Stroke | 7″ Diameter | 600 PSI Burst Rated | 3/8″ NPT Port

The High-Lift Standard for C10s and Chevy Square Bodies: The 2600 Series is the industry standard for classic trucks requiring more lift at lower pressures for a premium ride. Designed specifically for the heavier front ends and “bag-on-bar” rear setups of the C10 and Square Body community, these air springs deliver the maximum travel and “air-out” capability your build deserves. While most 2600-style bags stop short, ours are engineered to go the distance with 10 inches of massive usable stroke. Compressing down to 2.8″ and extending all the way to 12.5″, this is the definitive choice for trucks that demand maximum lift and a cloud-like ride.

Why the 2600 Series is the Pro-Truck Builder’s Choice:

C10 & Square Body Optimized: Specifically engineered for the chassis layout of Chevy C10s and Square Body trucks. The 7″ diameter provides the increased surface area needed to lift heavy truck front ends with significantly lower air pressure.
Direct Crossmember Mounting: While many classic cars involve opening up a front upper frame pocket, C10s and Square Bodies feature a similar factory opening in the crossmember. What makes this truck chassis unique is the industry-standard practice of capping that opening with an airbag mounting plate. Our 2600 air spring is designed with the large, flat top-surface required to bolt securely to most brackets for a professional fit.
Massive 10″ Stroke: Delivers a generous range of motion (from 2.8″ compressed to 12.5″ extended) giving you the “laid-out” look at the show and the maximum ground clearance needed for daily driving.
Control Arm Stability: Unlike skinny “long-travel” bags that can bow or snake, the 2600’s wide-body design is engineered to stay stable through the pivoting arc of a classic truck control arm setup, even at maximum extension.
Maximum Load Capacity: Built for the heaviest truck builds on the road, these bags feature a massive 3,055 lb max load rating at 100 PSI—handling big blocks and maximum payload without compromise.

Pro-Installer Clearance Tips:
Our air springs are built to perform under pressure, but even the toughest rubber can’t win against a sharp edge or a hot exhaust pipe. Because every vintage chassis is unique, ensuring your bags have “room to breathe” is a critical part of the installation:

The Three-Stage Check: You must verify your clearance at three critical stages: Fully Slammed, Normal Ride Height, and Fully Lifted.
Lower Arm Prep: On C10 and Square Body builds, the factory bump stop on the lower control arm must be removed. It is critical to grind smooth any sharp edges or metal stubs left behind from the removal of the bump stop bracket. These jagged edges will puncture the air spring as it expands and moves during travel.
The Moving Clearance Rule: While the bag may safely cradle or rest against the flat surface of the lower control arm when fully compressed (slammed), it must never rub against a sharp edge, a moving part, or a hot exhaust pipe during travel.
Custom Build Inspection: When cycling your suspension through its full range of motion (including full steering lock), keep a close eye on aftermarket upgrades. Ensure the bag stays clear of oversized sway bars, exposed cotter pins, protruding control arm bolts, or oversized brake conversions. Any contact with these components will lead to immediate abrasion failure.
