Rough Country 6521 Details

Rough Country 2.5 inch lift block kit 6521 for the Chevy C/K 1500, Silverado 1500 and GMC C/K 1500 and Sierra 1500 trucks are designed to upgrade your rear suspension and provide a simple remedy to an age-old problem that simply happens over the span of your vehicle lift.

Rough Country products are warranted to be free from defects in material and craftsmanship for the time periods listed. Some suspension components are prone to gradual wear and tear over time and therefore are not covered within the Lifetime Replacement Warranty.

Warranty Guard

This free protection supplements your manufacturer's warranty, guaranteeing that if you are denied repair due to having a Warranty Guard protected product on your vehicle, then Rough Country will foot the bill for your repair! For up to 5 years / 100K miles / or until your manufacturer's warranty ends, if there is a failure of a factory warranty-covered part due to installation of a Rough Country suspension product, Rough Country will cover the repairs at a factory authorized shop - all you pay is a $100 deductible!

Wear and tear items such as mountings, bushings, diminished shock and stabilizer dampening resistance, finish, dents and scratches, as these components and issues can wear out or occur naturally over time. These items are covered under a separate Limited Warranty along with other non-suspension items listed above. Replacements for non-defective items broken during off-road use may incur shipping charges.
