Stifflers Suspension transmission crossmembers are engineered to deliver quality, fit, finish, and functionality. At the core of these kits are Stifflers' unique single-tube crossmembers—adding strength and stiffness beyond that of OEM versions, while offering versatility without the excess weight. They also allow more exhaust clearance. To install, simply slide the mounting sleeves and reposition the spacers to cover your application. They work with OEM and aftermarket transmission mounts, and will maintain your current pinion angle. Stifflers Suspension transmission crossmembers include low-deflection polyurethane bushings in the mounts to dampen driveline vibrations and noise, but for racing applications they can be replaced by optional solid bushings. Order the crossmembers designed for fitment on your make and model.

Hooker LS engine swap transmission crossmembers are built to mount the transmission in place when switching to an LS engine. They are designed using CAD modeling/FEA analysis for optimal fitment, strength, weight, safety, and appearance. The crossmembers are manufactured from high-strength, low-alloy steel and then black powdercoated for maximum durability. They provide an engineered 3 to 3.5 degree engine/transmission inclination angle that is critical to obtaining suitable U-joint working angles. They are designed to be used in conjunction with Hooker LS engine swap brackets to provide a bolt-in installation of Hooker LS swap manifolds, headers, and exhaust systems for this application.

Stifflers Suspension weld-on subframe connectors are engineered to be stiff, lightweight, and easy to install. These full-length connectors are manufactured from 1.5 in. x 2 in. x .083 in. rectangular tubing. They are optimized using CAD/CAE software to provide the ultimate in stiffness, reduced weight, and maximized surface area between the subframe and connector. Stifflers subframe connectors feature crimped and welded tube ends to seal out moisture, while also increasing strength, and a laser-cut cross brace that reduces free span, reinforces the floor pan, and minimizes required welding during installation. All is given an industrial-grade powdercoat for long life. Welding areas are pre-masked, so no removal of powdercoat is needed before installation--a real time-saver!

Lowering your truck is cool, but when you do, where are you going to put the exhaust--under the frame? You'll run out of room, real quick. Well, Brothers Trucks has the solution in their crossmember exhaust brackets. These kits include meaty steel components--brackets, bolts, and template—that allow modification of the factory trailing arm crossmember for dual exhaust. They are ideal options if you don't want to remove the crossmember and still be able to tuck the exhaust up inside the frame, and they are the perfect solution for someone that doesn't have access to a welding machine. The provided metal template allows perfect alignment for the bolt holes and exhaust cut out. It utilizes an existing hole in the crossmember to locate the template, then insert one of the supplied bolts, clamp in place, and mark the remaining holes for drilling. For the center hole, the hole in the template is larger to allow a plasma torch to be used as a guide, but if you don't have a plasma torch other means, such as a hole saw, can still be used to cut the hole. Get more clearance for exhaust without weakening your truck's frame when utilizing Brothers Trucks crossmember brackets. Features: * Exhaust tailpipes fit through the holes in the frame for easier installation and more ground clearance when adding dual exhaust * Fits rear wheel drive trucks with trailing arm and coil spring rear suspension * Steel construction * Allows up to 3 in. dual exhaust system * Includes two pre-welded cut-out pieces, drilling template, and Grade 8 fasteners

It's a known fact; during acceleration, cornering, and braking your chassis will flex and twist. The more power you add or the stiffer the suspension, the worse it becomes. All this movement uses up valuable horsepower, decreases handling characteristics, and reduces ride quality. So why spend time and money improving your engine and suspension when it's attached to a flaccid frame? Stifflers Suspension F-150 chassis stiffening systems bridge the front and rear sections of the F-150 frame to significantly increase its stiffness and reduce the twisting and bending caused by suspension inputs and drivetrain torque. The systems are designed for ease of installation with minimal drilling--all other mounting locations use existing holes. Stifflers F-150 chassis stiffening systems are complete with integrated brackets for optional driveshaft safety loops (sold separately). So what does this mean for you? * Straighter launches * Less wasted horsepower * More responsive suspension tuning * Improved handling under cornering and braking * Better ride quality * Fewer squeaks and rattles NOTE: Other manufacturers' long bars cannot be used with these systems.
