P3 – Rough & Tough Cam Tubes

Do you have brake foundation problems on Intraax suspensions?

Due to their light weight design, after a certain portion of their service life, many users find the cam tube spinning in the spider bracket and this cam tube is loose in the spider bracket. Our THIC-1500 series cam tubes are press fitted into the spider channel so they cannot spin.

This sealed brake foundation component is built with optimized bearing journal alignment technology to enable low camshaft axial play and enabling the grease seals to prevent road contamination from entering the lubricant reserve and becoming an abrasive compound contributing to rapid wear of the assembly.

The rugged design of this important brake foundation component is made of high strength steel and engineered for maximum performance in heavy duty applications where other regular replacement parts can’t resist the beating generated by ROUGH & TOUGH road conditions.

In “OFF ROAD” applications, the THIC-1500 series Cam tube is the only fighting chance your brake foundation has to survive more than one reline. This design fears no wet conditions or dirt. With regular lubrication intervals, they offer;

  • Reliable and improved brake performance for many relines.
  • Reducing brake stroke and brake adjustment problems
  • reducing automatic brake adjuster issues by reducing vibration
  • 25% added brake life
  • Helps reduce brake noise
  • Reducing maintenance cost
  • Even wear pattern on brake shoes
  • Superior foundation integrity
  • Extra heavy duty performance
  • Available for 1st and 2nd oversize for damaged spider brackets                        See (** SPIDER +** system) on page P2 for easy trailer axle repairs
  • Durability way beyond anything else on the aftermarket

Rough & tough lube feature 

-THI 1500 series cam-tube system

The THI-1500 series tube feature a lubricant purge system that allows proper lubricant flow to the spider cam bearing journals whenever lubricating the assembly. This ensures proper lubrication of both cam bearing journals.

– Conventional tube enclosures

Conventional cam-tube assemblies usually have new lubricant flowing only to the spline end journal due to a positive seal at the spider end of the tube to prevent grease contamination of the brake foundation. This positive seal locks out new lubricant to be delivered to the spider bearing journal because the old lubricant cannot be purged out of the assembly.

– Convenient installation kit

Cam-tube enclosure assemblies come with all installation hardware in the box. Everything you need to install these components along with instructions and service bulletins for pertinent information on lubrication and other topics.

All tubes are available with matching camshafts for;

  • Standard spider channel size
  • 1st oversize ** SPIDER + bushing channel re-dimensioning system
  • 2nd oversize ** SPIDER + bushing channel re-dimensioning system

** Ask your Rough & Tough tube supplier for the SPIDER + spider bushing channel oversizing tool kit, and save your axles at a fraction of the replacement cost and a 30 minute per wheel end procedure.
