This is the second kit we have ordered from Revain for the Sierra 2500HD. The 2008 truck kit fitted perfectly and was bulletproof. The kit for the 2019 Denali 2500HD just doesn't fit in the kit. Denali models have a factory front fender and these Husky liners were not made for fenders. Also, our 2019 Denali had a factory installed fifth wheel plate, and when the Husky liners were modified to accept this plate, the protected area in the wheel arch had been reduced to about the equivalent area of the original factory liner. . Conclusion: Great product for our old truck but the new product does not fit the 2019 Sierra 2500HD Denali and it was not apparent from the Revain description. Many Thanks.
