Many Sonnax clutch hubs are designed for the extra-duty requirements of drag racing with Powerglide and other GM transmissions, for instance. Machined from a high-quality medium carbon steel forging, most hubs will accept five friction discs for the added load capacity needed in high horsepower race cars. All splines and thrust surfaces are precision-machined to exacting tolerances, and the unique lube hole pattern is designed to reduce drag on the friction discs in low gear. Sonnax clutch hubs are also available with or without lightening holes to reduce rotational weight.

Bowler Performance All-in-One transmission wiring harnesses for the Tremec T-56 Magnum transmission comes equipped with all the connections pre-wired into one harness for a simple installation and ease of use. The small epoxy sealed controller is mounted to the VSS output using the existing bolt, and once the unit is powered up, you will be able to connect via Bluetooth to your Apple or Android smartphone using Bowler's free app. The app will give you the ability to customize the input and output settings for each feature to ensure proper operation in your vehicle. The perfect finishing touch for any Tremec T-56 Magnum conversion, Bowler's All-in-One harnesses eliminate the need for any additional equipment to operate the reverse lock out or generate the correct speedometer signals coming from your Tremec T-56 Magnum. Previously, you would have needed up to five separate parts to perform all the same functions wrapped one of these harnesses. The more technology we incorporate into our hot rods sometimes requires specific input signals to allow everything to function correctly. With the two speed outputs available in these harnesses, you can independently control the output of each one further eliminating any need for additional equipment and connections. Regarding the reverse lockout, Bowler has incorporated the same speed setting feature as the OEs into the All-in-One harnesses, giving you better control over when the lock out is triggered. Bowler's All-in-One harnesses give you much greater flexibility in the components you are able to use and require less time wiring everything up, providing an easier solution for setting up your Tremec T-56 Magnum transmission. Choose the harness version designed for your specific transmission make. Additional notes: * Harnesses utilize a small, built in, epoxy sealed box that will control each of the three functions with power and grounding for each function through a switched +12 V circuit and a wire connected to the negative battery post or engine block. * Control of the reverse lockout solenoid is based on a user defined speed setting (default is set at locked above 4 mph and unlocked at 0 to 3 mph), eliminating the need for a separate lock-out control box. * For your electronic speedometer, the harness is equipped with two speed sensor outputs; the speed sensor outputs generate a square wave signal that goes from about -5 to roughly +5 V, varying in frequency as the speed changes. * Output will automatically shift and give you 0 to +10 volts for EMC input needing positive only signal. * The two speed sensor outputs are completely independent and can be calibrated separately with any pulse count and ratio you want, and are able to drive any common speedometer, cruise control, or ECM. * Tremec T-56 Magnum reverse lock-out module VSS with dual output, pre-set as GM 40-pulse output on one and 16-pulse output on the other and can be adjusted with your iOS or Android device. * Includes wiring for reverse lights, reverse lock-out, and vehicle speed sensor.

Pacific Performance Engineering transfer case pump upgrades cure the dreaded "pump rub." This occurs when the five positioning tabs holding the pump in place wear over time, causing the oil pump to come into contact with the housing itself. The result is a hole in your cover, leaking fluid, and the possibility of heavily damaging the transfer case. PPE transfer case pump upgrade kits consist of a new pump cover that offers a more secure method of mounting the pump, plus all the necessary gaskets. Order the kit recommended for your transfer case model.

The Spidertrax Off-Road high performance inboard oil seal kits are the perfect solution for sealing up your Spider 9 housing. Spidertrax starts with billet 6061-T6 aluminum and then machines a fully rebuildable seal housing that's designed to accommodate three external O-rings and two high performance axle shaft seals. Both O-rings and seals are pre-installed. With up to five total sealing surfaces, these inboard oil seal kits ensure oil stays where it belongs—inside the housing. The seal is designed to install on the inboard side of your Spider 9, near your differential. These kits come with one aluminum seal housing, three O-rings, two pre-installed high performance axle seals, and set screw. Key advantages include: * Designed to work with 1/4 in. tube thickness Spider 9 axle housings * CNC-machined 6061-T6 aluminum seal housing is fully rebuildable—both O-rings and axle shaft seals are available separately so servicing your seals is not only possible, but cost-effective * Three O-rings secure the aluminum seal housing inside the Spider 9 axle tube—the aluminum seal housing installs toward the differential side of the housing, so oil stays completely out of the axle tubes * High performance axle shaft seals (two are already pre-installed for you) are designed to accommodate shaft diameters from 27-spline all the way up to 40-spline—they are so stretchy in fact that they also handle almost any kind of axle shaft misalignment * Using the included set screw, each aluminum seal housing is designed to be securely locked inside the Spider 9 housing—this way you know the seal housing stays where it is supposed to when you install your axle shafts

Great for transplants! TransGo Automatic transmission modulator conversion kits provide a more aggressive and tunable pressure boost curve with engine vacuum instead of the vehicle PCM controlling PCS/EPC solenoid. TransGo modulator conversion kits include everything needed to add the internal modulator system with the oil pan off the transmission. From the outside of the transmission, you will need to connect it to an intake manifold vacuum source, however hardware is not provided for this. The kits do come with an oil pan-based resistor to pacify the control module for the missing EPC solenoid in applications where the computer will still manage the gear changes. TransGo includes: * Pressure regulator valve spring and snap ring * Brass fitting * Vacuum modulator, pin, valve, and bushing * Hold-down bracket * Elbow vacuum hose and spring * Four short zip ties * Five long zip ties * Vacuum tee * Resistor
