Sonnax universal remanufactured valve bodies have been uniquely designed to fit a variety of '99-later Chrysler applications, regardless of OE checkball or solenoid configuration. The convenience of stocking one SKU number for various applications saves time, money and interchangeability confusion. The channel casting has been resurfaced to SAE recommended flatness and surface finish. The seasoned casting warpage is now eliminated, removing cross-leaks and manufacturing burrs that resulted in clutch distress and shift complaints. A new separator plate is also installed, along with gaskets, to seal the critical surfaces between the valve body and channel casting. Heavy-duty/high performance accumulator pistons with dual-guide seals are installed to prevent piston-to-bore scuffing and restore clutch pressures due to leakage. Patented Sonnax valves are installed to restore hydraulic pressures and eliminate shift complaints, trouble codes, converter concerns and overdrive clutch distress. Their patented accumulator cover plate—made from stronger, thicker material and secured with additional screws—is also installed to prevent flexing or breakage. To guarantee the highest level of operational performance, these remanufactured valve bodies are tested on state-of-the art equipment to verify that pressures match OE specification. Product notes: * One SKU fits all applications, saving time, money and confusion * Resurfaced OE channel casting eliminates warpage, burrs, and cross-leaks cost effectively * New separator plate and gaskets provide critical seal between cast surfaces * Patented Sonnax valves and pistons restore hydraulic integrity of circuits to eliminate shift complaints and clutch distress * Patented Sonnax accumulator cover plate stronger than OE to prevent flexing and breaking

Failure of the intermediate stub shaft and direct drum are almost inevitable when transmissions are pushed to the limit. To maximize durability and improve clutch capacity in heavy-duty/performance vehicles, Sonnax offers Smart-Tech direct clutch drum and shaft kits, the first upgrade to eliminate every critical weakness. Most failures in these units occur where the direct drum and stub shaft connect. Even other aftermarket upgrades that rely on a heavy-duty shaft will sheer in this area under extreme conditions. Unlike two-piece assemblies, the all-in-one Smart-Tech easily handles the highest horsepower/torque levels. The unique one-piece clutch drum with integrated stub shaft is precision machined from high-strength steel to guarantee there are no splines to strip from the drum or weaken the shaft. The shaft itself is significantly thicker and 2 times stronger than the original. Due to its larger diameter, the integrated shaft must be used with the kit's custom, heavy-duty sun gear. Insufficient holding power is another area where many transmissions fall short, but installing thinner aftermarket steels and backing plates to increase clutch capacity isn't ideal. Those components increase clutch pack flex and heat build-up, making them the primary cause of repeat burn-up. To improve both performance and long-term reliability, the Smart-Tech's custom drum and piston hold an OE backing plate and seven OE frictions for 17 percent more clutch capacity than the six-friction stack-up. Sonnax Smart-Tech direct clutch drum and shaft kits feature: * One-piece design that eliminates weak point where drum splines strip and shafts break * Rugged shaft is 50 percent thicker and twice as strong as OE * Custom drum and piston deliver 17 percent more clutch capacity with optimum protection against burn-up * High-strength drum and shaft are precision-machined from hardened 8620 steel * Unique sun gear is precision-machined from 9310, heat-treated steel

Factory driveshafts are made from a smaller tube (there are 2 different types) and will flex and bend during hard acceleration, causing the rubber drives to wear out prematurely. The Driveshaft Shop torque tube driveshafts are made from 3 x .125 wall 6061 T-6 aluminum and uses The Driveshaft's own custom machined ends. This ensures that the shaft will not distort or break like the factory units, and offer units rated up to 1000 hp. Choose the driveshaft designed for your vehicle.

If your automatic transmission is struggling to downshift properly, the problem might be your aging transmission kickdown cable. Installing new automatic transmission kickdown cables from Pioneer can solve that problem and allow you to shift at lower rpm. These cables connect the throttle mechanism to the transmission. Old cables can break, become slack, or stick. Maybe it's time to replace that old cable with a new one. Pioneer cables are designed to fit and function just like the original part and are made to last.

C-clip eliminators, which were originated by Strange Engineering, are required by drag racing rules for good reason. C-clip type axles are retained by a clip above the spline portion of the axles. When the stock axle or differential breaks, the entire axle/brake/wheel assembly can slide completely out of the housing. Strange's C-clip eliminators eliminate wheel loss and worn bearing areas. The bearings are retained and the axles are held securely in place by the C-clip eliminators, which are bolted to the stock axle housing through the existing backing plate holes.

Extend the life of your forward clutch and input sprag with the upgrade performance of Sonnax heavy-duty 2-3 shift valves! Your factory valve is limited to applying the overrun clutch only in D3, 3rd gear; whereas these Sonnax valves apply it in D3, 1st, 2nd, and 3rd. This furnishes extra durability to clutch components in plow trucks, heavy-duty vehicles, and in high performance apps. The Sonnax 2-3 shift valves also work well with units operated by aftermarket electronic paddle shifters--allowing for full downshift engine breaking in 2nd gear, while the shifter remains in the D3 position. No special tools are required for installation; it's a transmission overrun clutch component worth exploring!

Sonnax billet accumulator pistons feature a stronger piston made from anodized billet aluminum with a dual-seal design. OEM plastic accumulators are prone to breaking and have poor sealing qualities and the metal rings currently offered with aftermarket accumulators also have issues with sealing. Sonnax piston's seals prevent piston-to-bore contact and the D-rings vastly improve sealing compared to aftermarket steel rings.

For years, the pages had continued to turn attempting to make the best transfer case cradle for the Suzuki Samurai. Low Range Off-Road set out to put an end to that story and succeeded. Addressing the weak factory brackets, their mounting points and vulnerability in high-torque situations, Low Range Off-Road End of Story (EOS) transfer case cradles mount with 17 points of contact to the transfer case and has a full circle backbone that distributes torque around the whole case. With this added strength comes a dramatically reduced risk of T-case breakage and extended gear life. Low Range also added a 4th frame mount location on the cradle arm, reducing the chances of the frame breaking at the mount points--a common occurrence with the Samurai. Additional features and contents: * Compatible with Low Range's Samurai transfer case e-brake (SB-EBK-LR) * A lower skid plate to protect the transfer case from trail abrasion * All necessary hardware included--even the necessary drill bits * CNC laser-cut, CNC press-bent, hand MIG welded * Zinc plated for corrosion resistance * Backbone * Long arm and short arm * Factory transfer case rubber mount * Full-color instructions
