Nissan Titan 2004 - 2025 | HD Kit

I purchased the RAS kit to help with porpoising that I had while pulling our tongue tow RV. The RV is 28'2" and has a dry weight of 6282 lbs. I am pulling it with a 2024 Nissan Titan (1/2 ton). The RAS raised the bed of the truck approximately 2". This system fixed the porpoising and did much more to help with the ride of truck while pulling the RV. The system has also reduced the amount of bounce after hitting a significant dip in the road. The ride while not towing the RV changed very little, if any. I would recommend the RAS kit to anyone to help with the same issues that I had dealt with. Note: just pulled the RV 400+ miles and really liked the drive. Review update – July 29th, 2026 Just returned from a 1,019 mile trip pulling the RV. We traveled multiple roadways, gravel roads, two-lane highways and interstates. All were traveled very smoothly. The ride whether loaded or empty was very smooth. Cornering was smooth, wash-boarding on gravel roads was smooth, just an overall smooth tow. Here are the status with a few included pics. Measurement taken by tech before and after the RAS system install. Before install - Driver front 36 1/8, rear 36 1/2 - Passenger front 36 1/2, rear 36 1/8 After install - Driver front 36 1/8, rear 38 3/8 - Passenger front 36 1/2, rear 38 1/2 My measurements after the 1,019 mile trip RV disconnected - Driver front 36 1/2, rear 38 - Passenger front 36 1/2, rear 38 RV connected - Driver front 36 1/2, rear 35 1/2 - Passenger front 36 1/2, rear 35 1/2 Overall, I am very satisfied with the RAS kit and the results were as research indicated. A much smoother all-round ride. I have already recommended the RAS system to several others.

Bought these to help with extra support while towing my camper trailer, took a short trip and these truly made a huge difference, my truck didn’t sag at all and rode extremely smooth

Hitching and unhitching my 26 foot travel trailer from my Nissan Titan is so much easier now and drives much better. Before I felt like the front end was going to come off the ground. Now there is only a little rise in the front end. Saved me from having to get a 3/4 ton!
