🔧 Optimize your GM G30/G3500 Front Suspension with Timbren GMFK15A Enhancement System (03-09) Review

Huge difference in ride. Compensates for potholes and bumps in the road. The truck drives much better. The difference is more than $500.00 shocks. The front was also aligned. I recommend it even if it doesn't compensate for the plow/weight.

Very good product, the truck went up where I wanted it to go up 2.5 inches or more.

I think aligning the buttons with the road will lift the truck off those shocks and give it some travel which will bring back a somewhat normal ride comfort. So far so good, we'll update when I get the keys to upgrade.

Timbrens are required when using a plow on a GM truck. I bought them through Revain but I think they were mispackaged as they weren't meant for my truck so I bought some matching plows from a local store (same part number).

I bought these front timbres to replace the fenders in my 01 GMC Yukon Denali which I have installed a Beyers SnowDogg MD 75 plow. They were so easy to install! Simply jack up the truck by the frame on each side, hanging the wheel (do not remove the wheel as the weight will help you clear space between the fenders. Get a long flat-headed pry bar and pry off the old fenders then oil lift the timbres with the WD40 on top and press them together by hand If you drop your car they fit perfectly your

I have an unusual use for them. I don't plow and don't have a steel bumper like most who buy them. Instead, I have a Yukon Denali 02 that has been lowered slightly with the control levers. Aftermarket levers are not known to come into contact with the OEM jounce bumper, also known as a jounce bumper in GM terms, as they have no overlay pad and compress. Although I handled better because I was lower to the ground, I felt like I had the same if not more body roll compared to the factory because I
