Recommended Suspension Support for a 2005 GMC Yukon XL Denali

Question:

Got a 2005 GMC Yukon XL Denali with factory air, but changed to spring load leveler shocks. My RV Toy hauler squats in rear. What do you recommend, Air Bags etc. Thanks

If your leveler shocks didn't change anything around your rear bump stops, I recommend the SumoSprings Solo Custom Helper Springs item # SSR-204-40. These replace your bump stops and limit the travel of your suspension while cushioning your ride.

The SumoSprings item # SSR-204-40 have a 1,000 lbs tongue weight capacity and work off a system called progressive load control. They only engage in proportion to the weight put on the rear of your Yukon. If you're not towing a trailer you won't even notice them.

There are no air bag kits for your 2005 GMC Yukon XL Denali the Air Lift item # AL59526, you were looking at, only work with the 2500 models.

What about the Blue Ox 2-Point Weight Distribution w/ Sway Control - 6-Hole Shank - 12K GTW, 1.2K TW Item # BLU75FR or the Reese Pro Round Bar Weight Distribution w/ Sway Control - 11,500 lbs GTW, 1,150 lbs TW Item # RE44FR would either help to level the Yukon to Trailer? Whichever one I need to be able to back up also with it installed. Thanks.

@Charlie Both one of those would work great so long as your trailer's tongue weight is within 600 lbs - 1,150 lbs for the Reese item # RE44FR or 800 lbs - 1,200 lbs for the Blue Ox item # BLU75FR. You can back up with either installed as well.

What about the Timbren Rear Suspension Enhancement System # TGMRYS4 ? And does my Yukon XL Denali bumper stop mounts have holes already to mount these in besides pressed into better secure them from falling out. Looks like these Timbren already have mounting holes in them. If that happen while on a trip my vehicle would snag. Thanks

@Charlie Timbren systems like the item # TGMRYS4 are pretty rough. You're going to feel it when you hit a bump during daily driving which is why I recommended the Sumosprings. These are confirmed to fit your Yukon and there is a hole to mount them in.
