Mud Flaps on Sierra 2500???

[carver 1]

I cannot use my Rock Tamer on my new Denali because the exhaust is not on the side, rather it exits to the rear. My alternative is to get a set of large mud flaps to prevent damage to the trailer. Any recommendations or source of appropriate mud flaps from members who have had this same problem and solved it will be greatly appreciated. This is something I never thought of.

Thanks,

Why not just cut the flap to accommodate? Might be able to mold some Poly Metal to the cut. Some DEI brand exhaust wrap on the pipe. Etc.

Go to an exhaust shop and get them to move the end of the pipe to another location. Coming out the back isn't too smart for a truck that is built to tow.

On mine, the exhaust exits at 45 degrees, at the RR corner, under the step-bumper. Is yours the same way?

We use a TowTector.....

MufflerMan cut the outlet and welded on a stainless extension that exits out the side.

I Franken'd my own flaps.

The people at rock tamer advised me that my model the RT was contraindicated.

You CAN use the Rocktamers on the 2500. Simply tilt the cross bars back and trim to length if required with the center mounting castings. They don't have to be straight up and down. As long as you have 12 inches from the tip of the exhaust to the face of the flap you will be fine. Been there and done that replacing one flap. Called Rocktamer and they gave me the tip.

I have mine mounted on top of the ProPride stinger but if they were mounted more normally the tilt works just fine.

Alternatively you could put a piece of metal plate but that's too much work.

I also have a set of Duraflaps on my 2500. Best mudflaps around and can be custom length. Mud Flaps For Pick Up Trucks SUVs by DuraFlap. They are no drill. Got a set for the front and back. Had the same setup on my Sierra 1500.

Duraflaps plus the RockTamers when towing = not dings to the front on either of my trailers.

Ron a followup. Saw your other post on your new truck and you mention your ProPride. You are good to go with the RockTamers.

[DHart]

Gary... good tips. Thanks.

Do the Duraflaps need the stainless steel weights to function as needed?

And, if you were to choose between the RockTamer or the Duraflaps, which do you feel would be the better choice in protecting the trailer?

[ghaynes755]

Ron they don't need the weights. I put on the the silver metal trims from Duraflap only for the look. They don't weigh anything. No shiny do dads on the front. Also both sets really cut down on the stuff being flung up to the underbody when not towing.

And with the RT's mounted to the top of the PP stinger makes it easy to pull the stinger off by grabbing onto the RT cross bar. I don't take the RT's off of the stinger.

I second the recommendation for Duraflaps (Mud Flaps For Pick Up Trucks SUVs by DuraFlap). I've had them make custom flaps for both my trucks (I wanted them cut extra long to protect the A/S) and am very pleased with how they work and look. Got a little fancy on the new truck and got the Celtic knot design. In the greater price scheme of new truck, new Airstream, WTH, upgrade the mud flaps! ;-)

I'm going to wait until I hook up to the AS to decide if I can use the top of the PP. The new Denali 2500 is higher than the F-250 it replaces and i might have to lower the adjustment on the stinger to keep the AS level, not having enough room for the collar of the RT. Definitely am calling Duraflap today to order. Thanks for all your advice.

The DF protects the truck. Not the trailer. RT only for trailer only, or both for protecting both.

Both products are highly rated on RV and truck forums.

I got rid of my Rock Tamers and installed mud guards from Weathertech.They fit perfectly with no holes to drill and they do the job without being ugly.
