Sonnax extreme duty intermediate shaft kit 22171B-08K for Chrysler 47RE, 47RH, 48RE transmissions delivers the ultimate protection against breakage in high-power, competition vehicles. A unique combination of innovative engineering and quality manufacturing guarantee maximum strength and resistance to fracture in even the most extreme applications.

This shaft features many unique refinements available only from Sonnax. It’s torsional design that allows energy to be absorbed, reducing peak loads to critical areas, is calibrated to balance stresses in high-power competition vehicles. The cross-section area — typically the weakest part — is strengthened with larger rear spline major/minor diameters and by eliminating both the small diameter undercut and selective spacer. Front spline durability also is improved by eliminating the small diameter undercut.

For applications where a direct replacement upgrade is needed, Sonnax heavy duty intermediate shaft 22171B-HD is recommended.

• Unique front/rear spline design increases durability
• Torsional design calibrated for competition vehicles dissipates peak stress
• Patented modifications to lubrication channel increase lube flow to prevent gear train meltdown
• Manufactured from 300M ultra high-strength steel for maximum strength and resistance to fracture
