Description

The S1 Built OEM Style AWD/RWD/FWD Rear Trailing Arms are hand-crafted to order, featuring reinforced gusset back plates ideal for auto-crossing or time-attack builds. These arms are designed to sit directly in the stock location and are compatible with all factory parts, though the use of S1 Built's E-Brake Cable Brackets is recommended. They come standard with custom 1-piece hubs and bearings and are finished with an Industrial Black powder coat. These trailing arms are engineered for AWD/RWD applications and can be adapted for FWD setups when paired with S1 Built's Axle Stubbies, which are sold separately. The arms are available with various lug patterns (4x100, 4x114.3, 5x114.3) and spline counts (23 or 28) to accommodate different differential types, including CR-V/Wagon and Jaguar differentials; rear differentials themselves are sold separately. Disk brake mounting points are integrated, making them incompatible with drum brake systems. Compatibility extends to specific Honda Civic and Acura Integra chassis, including EF 88-91 Civic/CRX, EG 92-95 Civic/Del Sol, EK/EM1 96-00 Civic, DA 90-03 Integra, and DC 94-01 Integra. It is important to note that bushings are not included and must be sourced separately. These products are intended for off-road use only, and their full potential relies on proper installation.
