Most Popular RAS for 2004 GMC Sierra

Always used air bags prior to this. As far as my needs go the Roadmaster works better. It does all it claims to do. I’ve loaded my truck with a 700 lb atv and 900 on the hitch and stayed level. Ride is smooth and the system has beenn100% reliable for the 25000 miles I’ve had it on my GMC Sierra 1500. Great product.

Finally decided to try the RAS system for the truck since I bought a bigger camper. Ordered it hoping it would get here in time for an install before our new camping trip. Arrived in plenty of time! Opened it up and went through the instructions and got to the install. So, advice…read instructions from start to finish before starting! LOL. I thought they sent the wrong parts and then I read the instructions completely and then said, oh yea, forgot that part. Ha ha. Anyway, there's always a better way to do things based on your situation and vehicle. So after a few different attempts, finally got my groove and install went just fine. As always…take your time, double check everything before tightening down! Anyway, completed the install and then took it for a quick drive. Real happy with it! Felt substantially like it can handle more weight. Will be trying it with the camper next week. Again, thanks to the etrailer peeps for getting it to me on time. Since Murphy's Law resides in my garage, I wanted plenty of time to do the install right…and they delivered! Literally. Thanks again and will look forward to the next order.

My 2021 Sierra Denali half ton was sagging under the tongue weight of my 3000 lb boat & trailer. I purchaesd and easilly installed the RAS custom leaf spring enhancement, set it at the lowest setting of 500 lbs and the tongue weight / sagging problem is fixed. I highly recommend this product !
