The feed limit low valve in listed GM transmissions limits line pressure feed to the default disable solenoid and control valves. Feed limit low pressure is also connected to the boost ball system for "A" and "B" clutch control. This feed limit low valve is subject to significant side-load force, resulting in severe wear and pressure loss to the default disable solenoid and connected control valves. Such pressure loss can put the vehicle into default mode at high speeds, resulting in momentary wheel lockup, sudden downshift to 2nd gear, harsh shifts or a P0747 code. The feed limit low valve can wear out in as little as 30,000 miles, with many vehicles requiring service by 35,000 miles. A national recall from GM includes installing updated software that monitors valve performance and wear, then triggers a check engine light and reduced propulsion message 10,000 miles before failure. Vehicles are then limited to 5th gear, commonly referred to as limp mode, until the valve body is serviced to address the failed valve. Sonnax patented this drop-in feed limit low valve kit to overcome bore wear, restoring proper valve function immediately without the need or expense of replacing the entire valve body. The valve reroutes the balance circuit through an internal passage, significantly reducing the side-load force, while upgraded materials prevent future wear. * The kit overcomes drivability issues related to the GM 10-speed wheel lockup recall * Patented valve and sleeve combination overcomes bore wear and significantly reduces future side loading of the valve * Hardcoat anodized aluminum valve and wear-resistant sleeve combat premature wear * Drop-in Zip Valve parts install quickly and easily * Kit contents: -- Valve -- Sleeve -- Spring -- Retainer -- Drill -- Rivet (Note: The OE feed limit low valve is susceptible to premature wear and therefore a critical failure point. Replacing the valve is recommended even if the transmission isn't exhibiting problems and the valve passes a vacuum test.)

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

Low Range Off-Road clutch kits are available for a wide variety of years, makes, and models. LROR has done their research to find some of the best parts from several clutch manufacturers. If you're looking to replace your old worn-out stock clutch and don't need anything with more grip, LROR's Stage 1 OE-replacement clutch kits are economical and meet or exceed OEM requirements. Like almost all of their clutches, most feature DST (diaphragm spring type) pressure plates--much better than many other aftermarket clutch covers. For an upgrade, look to LROR's Stage 2 dual-surface organic and ceramic clutch kits. They easily surpass factory clutches and provide much better reliability, great engagement, and heavy-duty friction without compromising OE clutch feel. The organic material on one side reduces chatter and maintains near-stock feel. The ceramic side far surpasses woven glass or organic materials. It can handle repeated hard usage because of its impressive characteristics and much higher coefficient of friction. Low Range Off-Road Stage 3 high performance, all-ceramic clutches are their extreme-duty kits. They provide up to twice the life of factory clutches with seriously improved clamping force. Their lighter design reduces the chance of catastrophic failure due to excessive rpm and from clutch spin-down where the disc continues to spin after being disengaged. Also, ceramic clutches don't fade like conventional clutches when they get hot. You get the same solid performance hot or cold. Most Low Range Off-Road clutch kits include the following: * Clutch disc * Clutch cover/pressure plate * Pilot bearing * Release bearing * Alignment tool * Grease packet * Installation Instructions

DRP Performance offers premium low drag bearing kits for a wide range of applications, including many Ford, Chevy, and Pontiac cars from the 1960s, '70s, '80s, and '90s. Low drag hub components reduce friction and lower temperatures, making your wheels spin easier, delivering more horsepower to the track—all while reducing maintenance and making your race car faster. Enhance your performance on oval track asphalt, oval track dirt, drag racing, road racing, and street applications. Kits include a DPR bearing spacer, DRP Premium Super finished Bearing Kit, and DRP Ultra low drag seal. Here are details on each component: * DRP Bearing Spacer: A difference you can feel—in the pits and on the track. Bearing spacers make the most difference of any low drag hub upgrade. Properly installed, these spacers will provide an immediate increase in hub free spin, an improvement large enough to feel just by pushing the car around. And the benefit doesn't stop there. Bearing spacers make the most difference when a side load (cornering force) is applied. Drivers have commented on how much faster a car with bearing spacers free rolls when entering and through the center of the corner. Bearing spacers simplify and reduce hub maintenance. Spindle nut torque is no longer sensitive. In fact, with spacers installed, you can tighten the spindle nut as much as you want without overtightening the bearings. (DPR recommends 20-40 lbs.-ft.) Bearings will run cooler and do not need to be repacked as often. Bearing spacers are simple to install. DRP bearing spacers have a threaded adjustment, allowing the user to quickly set bearing end play or preload. A set-screw locks the spacer at the desired adjustment. Once installed, they do not need to be readjusted unless you replace the hub or bearings. Bearing spacers are used in virtually every application in professional motorsports. * DRP Premium Super finished Bearing Kit: Reduce bearing temperature by over 100 degrees F verses stock bearings! Increase free spin by over 250 percent! DPR starts with premium quality bearings and puts them through a super finishing process. This process removes the grind marks and greatly smooths the surface of the bearing roller, while leaving a "hatch" pattern to retain grease. Quality wheel bearings will last the life of most racing applications. * DRP Ultra Low Drag Seal: …billet aluminum, full PTFE sealing lip, reusable, great for any application: dirt, asphalt, road race, street Decrease seal drag by over 1,000 percent! Air gap seals create an "air curtain" to keep debris out and eliminate drag completely! DRP Ultra Low Drag hub seals are true, purpose-built, high performance seals. The housing is made from lightweight aluminum. The sealing element is a special PTFE blend, giving it natural low friction qualities. Seals are reusable. Order the kit recommended for your vehicle.
