Detroit Speed FN988TA Assembled Center Sections

Detroit Speed FN988TA assembled center sections deliver next-level performance, combining the quiet efficiency of the Ford 8.8 gear set with a dropout center section and integral torque arm mount. They are ideal solutions for vehicles running a 9 in.-style housing. While the Ford 9 in. is known for strength, its design can be noisy and less efficient--issues the 8.8 solved decades ago. The FN988 merges the best of both, featuring a 31-spline Truetrac differential, high-quality bearings, heavy-duty 1350 Series yoke, and five gear ratio options to deliver modern driveline control, strength, and durability--engineered, tested, and proven the Detroit Speed way. Detroit Speed FN988 torque arm assemblies are offered with or without REM polished gear sets to further improve the operation of the rear differential assembly. Select a center section designed for your vehicle. Features and benefits: * Engineered for strength -- Cast from nodular iron and machined to exacting tolerances -- Forged steel bearing caps for high-horsepower reliability * Quiet, efficient operation -- Transmits more power to the tires while eliminating gear whine * Ease of installation -- Dropout center installs into 9 in. housings and eliminates C-clip axles * Integral torque arm mounting -- Refines the packaging and installation of a 9 in. housing in 3rd/4th Gen Camaro applications * 31-spline Truetrac differential -- Delivers smooth, predictable power distribution and superior traction * 1350-Series yoke -- Heavy-duty construction for high-torque durability * Built to Detroit Speed standards -- Precision assembled for performance, reliability, and perfect fit * Multiple gear ratio options -- 3.08, 3.31, 3.55, 3.73, and 4.10 gear ratios available * REM polishing process creates a smooth micro-textured surface on the gearset for enhanced oil retention properties, resulting in reduced heat and friction, increased component life, and quiet, efficient operation (not on all assemblies)

Artec Industries JK APEX Front Axle Trusses

Artec Industries JK APEX front axle trusses introduce a whole new level of cost savings, strength, weight savings, simplicity of installation, precision fitment, and complete axle protection never before seen in the industry. The key feature that sets the APEX truss apart is its unique peaked shape top which provides extra rigidity to the whole truss, while allowing both a reduction in weight (vs. using a thicker material top) and eliminating long weld seams. Previous versions with long weld seams have led to extra weld warping of the axle, longer install times, and can be inconsistent. This peaked structure not only applies to the axle tube between the coil perches, but extends underneath the coil perches as well—forming a complete truss from end to end of the axle, an industry first in an OEM axle application. The JK APEX truss has been tested and proved to hold up to both extreme applications and daily driving. Product details: * Patent pending APEX truss peaked top design provides more rigidity than a flat top truss design * Truss is CNC precision laser-cut in-house from 1/8 in. mild steel for a lightweight yet strong solution—only 7 lbs. * Truss is CNC precision-bent in-house for a great fitment; literally drop the truss in place on the axle and it's ready to weld—no puzzle piece assembling * Designed using 3-D models directly from Dana Corp and Jeep for an amazing fit and clearances with surrounding components * 70 percent less welding needed than previous truss designs means less warping, faster turnaround, and lower costs * All long seams are bent so you don't need to spend time welding them together * APEX design continues under the OEM coil buckets for complete end-to-end axle reinforcement—an industry first * Dimpled holes provide weight reduction, rigidity, and strength * Contours to the cast steel differential and can be welded with normal MIG welder and moderate pre-heating and post-heating * Provides worry-free wheeling of up to 37 in. tires on stock JK axles * Truss strengthens the weakest sections of the axle—under the coil perches, around the control arm brackets, and where the tube enters the casting * Low-profile design doesn't go over differential and allows usage in vehicles with only slight lift
