Transfer Case Drop Kit for 1973-1991 Chevy/GMC Truck/SUV

If you’ve lifted your 1973-1991 Chevy or GMC Truck/SUV, this Transfer Case Drop Kit helps correct driveline angles. It lowers the transfer case output just enough to reduce vibration in the front driveshaft and ease wear on U-joints for lifted setups. 

Why Choose This Kit?

• Driveline Vibration Fix — Reduces angle on the front driveshaft, which is especially noticeable on bigger lifts and more aggressive use. 
• High-Quality Steel Spacer — Uses 1-piece heavy steel tube spacer/bracket construction to ensure strength and consistency. 
• Durable Finish — E-coated to resist rust and corrosion, important in older frames or exposed applications.
• Simple Installation — Bolt-on kit using existing hardware; minimal modification required. 

Fitment & Specs

• Fits Chevy/GMC Trucks and SUVs from 1973-1991 that use 4WD drivetrains. 
• Kit part number: Rough Country 7508 / BDS version available. 
• Weight: ~1.85 lbs.
• Includes T-case drop spacers and hardware. 

Important Notes

• Recommended especially if you have 6″+ lift; lower lifts may not require this correction.
• Front driveshaft may require clearancing or alignment with full droop to avoid binding. 
• Check exhaust crossover clearance—raised transfers or modified crossmembers may interfere.
• After install, re-check driveline angles and U-joint conditions up front. Regular inspection helps longevity.
