QuickCar Racing Products Shock Absorber Kits: Race-Engineered Suspension Components

When it comes to dialing in suspension performance on the track, few names carry as much weight as QuickCar Racing Products. Founded in 1992 and headquartered in Lebanon, TN, QuickCar has spent more than three decades developing purpose-built components for the high-performance and racing markets — and their lineup of shock absorber kits is a testament to that focused expertise.

Torque Absorbers: The Heart of the QuickCar Shock Kit Lineup

QuickCar's best-known contribution to the shock absorber category is their Torque Absorber system — a racing-specific solution designed to manage driveline shock loads and chassis flex at the moment of hard acceleration. These are not conventional passenger-car shock absorbers; they are engineered specifically for the stresses of oval track and short track racing, where torque spikes from a high-horsepower engine can unsettle chassis balance and wear out components prematurely.

The lineup includes several configurations to suit different car builds and rule sets. The Standard Torque Absorber (part 66-500) and the Long Style Torque Absorber (part 66-499) offer racers flexibility in mounting and fitment, with lengths available to match a wide range of chassis configurations. Notably, the 66-500 is IMCA Legal, making it an approved choice for competitors in one of the largest sanctioning bodies in grassroots oval racing.

Biscuit Tuning Kits: Fine-Tune Your Torque Absorption

What truly sets QuickCar's shock absorber kit system apart is its Biscuit Tuning Kit approach. The torque absorber units use interchangeable rubber "biscuit" bushings that come in multiple durometer ratings — from Blue Extra Soft to Black Hard — allowing crews to fine-tune the stiffness of the torque absorption to match track conditions, tire compound, and driver preference. The Torque Absorber Biscuit Tuning Kit (part 66-508) bundles the full range of biscuits from extra soft through hard, giving teams a complete tuning palette in a single package without having to source individual components piecemeal.

Travel Indicators: See What Your Suspension Is Doing

Complementing the torque absorber units, QuickCar also offers Travel Indicator accessories (part 66-512) designed to work directly with the 66-499 and 66-500 absorber bodies. These indicators let crew chiefs and drivers measure actual suspension travel after a run, turning qualitative feel into quantifiable setup data — a small but meaningful advantage when chasing tenths of a second.

Aluminum Suspension Tubes: Lightweight Structural Components

Rounding out the shock absorber kit category, QuickCar produces scalloped aluminum suspension tubes — such as the 38-090 — in a variety of lengths and thread configurations. Black-anodized for durability and corrosion resistance, these lightweight tubes are machined to precise tolerances, reflecting the same commitment to quality that has made QuickCar a trusted supplier for both amateur and professional race teams for over 30 years.
