Sonnax Externally Adjustable Low/Reverse Servo Kits

Sonnax externally adjustable low/reverse servo kits make band maintenance quick and easy. They offer an ideal way to improve reliability and make staging more consistent and predictable. Checking L/R band adjustment after repeated use is good practice. Unfortunately, OE servos with steel covers are difficult to adjust in a vehicle, so a quick check with such a servo installed is impractical for most racers. Sonnax externally adjustable servos provides an improved design that makes checks and adjustment of the L/R servo easy. There is no cover or access plug to remove because the adjuster itself extends through the cover. A quick check is done simply by pushing on the end of the adjuster and observing the movement of the piston relative to the servo cover. Select the kit designed for your transmission. Features: * Quickly check and adjust the low/reverse band to prevent trans-brake malfunction * Unique servo cover and adjuster design makes in-vehicle band service easy * Works with or without OE 1-2 accumulator piston Included: * 6061 Anodized billet aluminum cover * Piston * Pin * Jam nut * Cover seals -- Two PTFE, one extra * Piston seal * Cover O-ring * Pin O-ring Kit for TH400 will also include: * Cover flange O-ring * Bolts (6) * Washers (6)

Spidertrax Off-Road High Performance Inboard Oil Seals Kits

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
