Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque. They perform like a limited-slip differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant. These replacement units are available for dozens of axle applications.

Lakewood safety bellhousings are designed for maximum performance and durability. They are cut on CNC 5 axis laser cutters rather than plasma cutters to improve finish quality, reduce heat damage and warpage from the plasma cutter, improve speed of manufacture, and make them all exactly the same. All bellhousings feature a scalloped plate on the bottom of the transmission surface made from G70 grade steel (70,000) psi which will help eliminate stripping the transmission bolts. The engine plates are made of H60 grade material and the bells are roto-brated after welding to relive any stresses created from the hydro forming, annealing, or welding process prior to machining and painting. The roto-brating process also closes the metal on the outer surface making them stronger. Ever wonder how the SFI tests bellhousings like these Lakewood safety bellhousings? First, they bolt the bellhousing to a machine with a cast iron flywheel and saw inside it. Then they spin the flywheel, causing the saw to cut through it until it explodes. If the bellhousing can contain the explosion, the bellhousing is approved. These safety bellhousings are a safeguard to minimize the destructive effects of such an explosion. Don't take unnecessary chances with your safety and the safety of innocent bystanders--Lakewood not only provides top-notch products, they also provide peace of mind.

TCI trans-brake kits allow you to achieve maximum torque converter stall for quicker and more consistent reaction and 60 ft. times. They work like this: When the trans-brake is engaged, the vehicle can roll neither forward nor backward, and as you press on the accelerator, the engine can rev as high as the torque converter stall. Once the brake is released, power is immediately transferred to the rear tires, with less parts breakage than with a manual transmission.

RAM clutches for 'stock clutch rule' classes give you unmatched performance and durability. The 10.5 in. diameter assembly utilizes a billet aluminum pressure ring with a riveted steel heat shield that provides a durable mating surface for the clutch disc. A 3,000 lb. pressure spring provides increased static pressure over stock clutches. Used in conjunction with a RAM 6-paddle solid hub disc, this combination weighs in at just over 15 lbs. If your rules require a full facing or sprung hub disc, the RAM 300 Series organic racing disc provides the best holding power of any organic disc available and adds only about 2 lbs. to the total weight of the set. RAM offers a lightweight 17 lb. billet steel flywheel for Chevrolet that matches the above components. If you are required to use all-steel components, RAM offers a similar 10.5 in. pressure plate with a nodular iron pressure ring. This unit uses the same heavier pressure spring for increased holding power. All RAM street stock clutches are completely rebuildable.
