As described. Quality construction. Install wasnt too difficult.
Was was easy to install, definitely recommend having a floor jack and tall jack stands if you install it yourself. Great product and I love the look it gave my truck.
Blocks for perfect and measure properly. This was exactly what I needed for my F100.
Good product, easy install and the guys at 4 wheel parts are knowledgeable
The team did a great job installing a Pro Comp Rear block on my truck. It took the item longer than expected to arrive, but they got the job done. They scheduled me a week out for installation and completed it by the end of business. Please be mindful of the delays, shortages, etc in the world today. They are very busy. Items will take longer to arrive. I would recommend calling to check in on the item after 2-3 weeks. The second time I called, they had just received the item.
My truck looks great and the ride hasn’t changed at all. If anything it got better.
Q: What size U bolts are needed to put this on a 2019 Colorado Z71? Are there any break line modifications needed? Answer this question
A: You may need a longer shock for the 2.5” lift as well. I found that I needed to grind off about 1/16” - 1/8” off of the centering pin for the blocks to sit flush on the axle plate. 2019 Colorado Z71

A: 10.5” U-bolts work comfortably. The Rough Country lift kit comes with a bracket extension for the brake lines. The Zone 5.5 inch lift kit says to just bend the factory bracket down to free up the brake lines...

A: U-bolt required for a 2.5” block: 9/16” x 2.525” x 10.25-10.50” You will need to check the slack of the brake line to see if you have enough room to use the 2.5” block.
