Complete Kit B or P 64- 72

The RATECH Complete Kit B or P 64–72 differential installation kit (SKU RAT311K) is engineered for law enforcement and military personnel who demand precision drivetrain maintenance and restoration. Designed for GM 10-bolt differentials in 8.2-inch applications, this comprehensive kit addresses the critical components required for proper differential assembly, ensuring optimal performance under demanding operational conditions. Whether you're maintaining fleet vehicles, restoring tactical transport, or servicing duty rigs, this kit eliminates guesswork by bundling every consumable and wear item needed for a professional-grade installation.

The Complete Kit B or P includes matched bearing sets, crush sleeve, gasket seals, hardware fasteners, and precision shims—each component calibrated to OEM specifications for the 8.2-inch GM 10-bolt platform. Crush sleeves regulate preload on differential pinion bearings, directly affecting noise, longevity, and load distribution under acceleration and braking stress. Matched bearings prevent race misalignment and premature wear, while gaskets and seals maintain fluid integrity and prevent contamination—mission-critical on vehicles operating in austere or high-moisture environments. The included shims allow fine-tuning of carrier bearing preload and ring gear backlash, essential for eliminating chatter and ensuring repeatable driveline function across repeated duty cycles.

Mechanics, fleet technicians, and vehicle maintenance personnel working on GM 10-bolt platforms benefit most from this complete assembly solution, which eliminates the need to source components individually—reducing downtime and assembly errors. The kit's 5.35 lb compact form factor (6.8 x 3.6 x 6.8 inches) fits easily in service kits or mobile maintenance vehicles. Proper installation of these matched components ensures that your tactical or duty vehicle maintains consistent driveline performance, reliability, and safety margins critical to law enforcement and military operations. This kit is compatible exclusively with 8.2-inch GM 10-bolt differentials and should be installed by qualified technicians familiar with differential assembly procedures.
