Chassis Engineering Four-Link Kits, Ladder Bars & Drag Racing Suspension
Chassis Engineering builds the hardware that makes fast cars hook and launch. Since 1974, they've been manufacturing chassis fabrication components, rear suspension systems, and structural hardware for drag racing and street/strip performance builds — the kind of parts that go on cars where the chassis is as important as the engine. If you're building a serious drag car, a street/strip machine, or a custom chassis from scratch, Chassis Engineering has the components that serious builders spec.
Four-Link Rear Suspension Kits
Chassis Engineering's four-link rear suspension kits are the foundation of a properly engineered drag racing rear suspension. A correctly designed four-link system controls rear axle movement under acceleration with precision — managing pinion angle, controlling axle wrap, and transferring weight to the rear tires in a controlled, repeatable manner that maximizes traction off the line.
Chassis Engineering four-link kits are available in weld-in configurations for custom chassis builds and in application-specific designs for popular muscle car and truck platforms. Each kit includes precision-cut tubing, rod end hardware, and mounting brackets engineered to correct geometry specifications. These are not universal components adapted to fit — they're purpose-built drag racing suspension hardware.
Ladder Bars
For builds where a full four-link isn't the right solution, Chassis Engineering's ladder bars provide effective axle control in a simpler, more compact package. Ladder bars are a proven solution for leaf spring-converted drag cars and custom chassis builds where packaging constraints limit four-link geometry. Chassis Engineering's ladder bars are constructed from heavy-wall DOM tubing with precision-machined rod end mounts and correct geometry for effective weight transfer under hard acceleration.
Coilover Mounts & Chassis Fabrication Components
Chassis Engineering's coilover mount kits, crossmembers, and chassis fabrication components give builders the structural hardware needed to integrate coilover suspension into custom and modified chassis correctly. Their weld-in coilover mounts are precision-cut and gusseted for the load demands of performance suspension, eliminating the improvised fabrication that compromises structural integrity and suspension geometry on less carefully built cars.
Supporting fabrication components include torque arm mounts, panhard bar brackets, sway bar mounts, and structural gussets — the hardware that ties a chassis together correctly and keeps it together under the repeated stress of hard launches and high-speed runs.
Street/Strip & Race Applications
Chassis Engineering products are used across the full spectrum of drag racing and street/strip builds — from bracket racers and street/strip muscle cars to dedicated Pro Street and outlaw drag builds. Their components are engineered for the specific load demands of drag racing — the violent weight transfer, axle torque, and structural stress that separates drag racing hardware from general performance components.
Why Ozkonic Kustomz
We carry Chassis Engineering because drag racing chassis work requires purpose-built hardware — not adapted street parts. Genuine Chassis Engineering product, 50 years of drag racing fabrication engineering, and the components that serious builders trust when the chassis has to perform. Build it right from the frame up.
