Chevrolet C-20/C-30 1973-1991 6/8 Deluxe Drop Kit


Product Overview


Our Big Boy drop for the C-20/30 trucks for the ultimate in a slammed tow pig, daily driver or weekend cruiser. Combining 3" drop spindles and 3" drop coils in the front for a true 6" drop. No cut coils here, our coils were designed specifically for this application and are made in the USA. The rear parts were all developed in house with heavy duty construction and ease of installation in mind. Our flip kit not only drops your truck 8" but sets the correct pinion angle for you at the same time. New u-bolts & hardware is included for a hassle free installation. The c-notch give the additional axle clearance for a smooth ride and is fully bolt in with no welding required. It features an internal gusset to keep the frame straight and stout. Coil springs and rear parts are powdercoated Black for a worry free finish.

Nitrogen drop shocks are required for proper fitment and rear shock extensions are highly recommended to correct the shock angle. If additional load capacity is necessary for towing or hauling we also offer an air bag helper kit that will bolt on using existing c-notch mounting locations and includes a crossmember to eliminate frame flex.
