About Progress Technology

Since 1995, Progress Technology has grown from a regional suspension distributor into one of the most respected names in American-made performance handling components. Headquartered in Anaheim, California, the company — operating under The Progress Group Inc. — designs, engineers, and manufactures its entire product lineup in-house, giving it tight control over materials, tolerances, and quality at every stage of production.

The brand's guiding motto, "Advancing the Art," captures its commitment to pushing suspension engineering forward rather than simply repackaging off-the-shelf components. Every sway bar, spring, and coilover system that leaves the Anaheim facility has been developed using an in-house shock dyno to calibrate damping curves and a load cell to match spring rates — a level of internal validation that is uncommon in the aftermarket suspension segment.

Race-Proven Performance

Progress Technology products are not just street-tested — they are race-validated. Winning teams in SCCA, IMSA, NASA, SCTA, World Challenge, and Honda Challenge have all relied on Progress suspension components. Toyota Motorsports has also selected Progress Technology to equip Scion tC Pace Cars and Celebrity Challenge vehicles, a testament to the brand's engineering credibility at the professional motorsports level.

A Complete Suspension Lineup

The Progress Technology catalog is focused squarely on the suspension systems that matter most to enthusiasts and daily drivers alike. The brand's flagship Coil Spring / Tie Rod Sleeve / Sway Bar Kits deliver a comprehensive handling upgrade in a single package — addressing body roll, bump-steer, and spring rate all at once. For trucks and SUVs that need a targeted anti-roll upgrade, Progress offers purpose-built Sway Bar Adapter Kits that integrate with factory mounting points for a clean, bolt-on installation.

Enthusiasts looking to lower their vehicle's center of gravity and sharpen response can explore the brand's Coil Spring Lowering Kits and individual Coil Springs, both manufactured using high-tensile chrome-silicon spring materials wound on CNC coiling machines, then stress-relieved, pre-set, shot-peened, and powder-coated for lasting durability. For those seeking the most tunable ride possible, Progress Technology's Coilover Adjustable Spring Lowering Kits pair application-specific cold-wound springs with twin-tube dampers and noise-isolating mounts — a system developed through decades of engineering experience and extensive track testing.

Made in the USA, Backed for Life

Every Progress Technology sway bar and sport spring is proudly manufactured in the United States and backed by a limited lifetime warranty. The brand's vertically integrated production model — from raw alloy steel bent on precision CNC machines to laser-cut ends MIG-welded in calibrated fixtures — ensures consistent quality across the entire lineup. Whether you are building a weekend autocross car, upgrading a daily driver's handling balance, or fine-tuning a truck for towing stability, Progress Technology offers a suspension solution engineered specifically for your platform.
