RAM Truck Pulling Custom Order Clutch Kits

RAM truck pulling clutch kits are custom-assembled for your specific application. These units feature a heavy-gauge steel cover with welded spring guides and a steel pressure ring. Flywheels are available in 30 or 40 lb. weights, as well as in billet aluminum. The clutches can be set up with either 5135 or 5191 compound iron discs with 1 to 10 splines. Single disc slipper-style clutches can be used with engines producing up to 800 hp, or where very limited slipping is desired. These clutches utilize the same quality components as the RAM dual disc pulling clutches. These units can be assembled with your choice of sintered iron disc materials and flywheel weights. Dual disc clutches will allow a more controlled slip as the vehicle comes out, without severe wear or every-round maintenance. Dual disc clutches are built to fit different stock depths or deep bellhousings.

Trail-Gear Rock Assault Custom Axle Housings

Years after releasing their successful Rock Assault 9 axle housing, Trail-Gear decided to add a Toyota 8 in. version to the Rock Assault lineup. This housing is built to the same specifications as the Rock Assault 9 axles; however, they're built to accept the popular Toyota 8 in. differential. These housings have been tested in W.E. Rock, CalRocs, and King of the Hammers—so you know they'll stand up to the toughest terrain on earth. Trail-Gear started with a 1/4 in. thick formed shell for the center section made from A36 steel. This is a high-strength, low alloy, structural steel plate with a minimum yield strength of 36,000 psi. All of this is attached to an equally strong 1/2 in. thick faceplate for anchoring the DOM axle tubes. The axle tubes are secured by the industry's first 3-Point Attachment System, giving the tubes superior support and engagement into the center section. Trail-Gear also faces the center section to ensure your differential mounts flush against the axle housing to prevent any leaks. Rock Assault Fabricated 8 Housings are offered with 3.5 in. O.D. axle tubes with your choice of 1/4 in. or 3/8 in. wall thickness. NOTE: The housing is shipped with no ends. Housing ends must be sourced and installed to complete axle. Portal style ends are commonly used for this application.
