1968-1970 Mopar B-Body Extreme Subframe

Description

> Description The Speedtech ExtReme front subframe delivers an all-new take on geometry and quality for your 68-70 B-body , giving you wide tire fitment, maximized rigidity, and serious handling performance — whether on the track or the street. Engineered with proprietary geometry and tuned with QA1 or JRi coilovers and a precision dual-power rack from Sweet Mfg., the system provides predictable, connected feedback with a refined ride quality that doesn’t compromise drivability. Optimized suspension geometry, forged aluminum spindles, and clearance for up to 315mm front tires ensure every aspect is engineered for real-world performance. AGGRESSIVE STANCE, WIDE TIRE FITMENT Designed with wide wheel and tire combos in mind, this subframe accommodates up to a 315/30/18 tire with full steering clearance. High-clearance control arms and optimized geometry let you slam the car for that strong pro-touring look without compromising performance or drivability. PRECISION STEERING FEEL, DUAL RACK PERFORMANCE At the heart of this system is a dual power rack and pinion from Sweet Mfg., giving you a quicker ratio and improved feedback for confident cornering. Combined with our billet steering arm and ExtReme spindle geometry, you’ll feel in full control at every turn. RACE-BRED STRENGTH, STREET-READY RELIABILITY Box-welded construction with tabbed-through gusseting maximizes torsional rigidity, while our 7075 forged aluminum spindles bring lightweight strength to the front end. It’s engineered to take abuse—on and off the track. BINDLESS REAR END SUSPENSION Torque Arm Rear Suspension, teamed with articulating trailing arms, is designed to articulate fully through the motion of your suspension travel, giving you better handling and a higher quality ride. MADE IN THE USA WITH PRIDE Every Speedtech subframe is built right here in the USA, using premium materials and expert craftsmanship. We believe in building it right the first time—with no compromises. BOLT-ON INSTALLATION, NO GUESSWORK This isn’t a weld-in or cut-up job.
