To see how the RAS kits progressed over the years, we show the 1st generation, the 2nd generation, and finally the 3rd generation and (present) kit for rear leaf spring suspension.
1st Generation Kit
As the different vehicle manufacturers and their models changed over the years, so did the RAS kits change. The 1st kits had a lighter coil tension spring and were designed for lighter mini pickups such as the Toyota Tacoma, Ford Rangers and SUV’s. During this period the 1st generation kits were manufactured, for most SUV’s that had rear leaf spring suspension, which gave the vehicles a hard truck like ride.
2nd Generation Kit
When these vehicles in 2000 started changing to rear coil spring suspension, the new 2nd generation kits were introduced. These kits had a larger more powerful coil tension spring designed for ½, ¾ and 1 ton pickups. This kit proved very popular and became the rear suspension upgrade of choice, recommended by four of the major Insurance Companies, who insure thousands of churches and their 12 and 15 passenger vans. RAS was chosen to help make their vehicles safer and less prone to rollover. With the improvement in load carrying, handling and all the other benefits that RAS provides, it has now become the fastest growing rear leaf spring upgrade on the US market.
3rd Generation Kit
In 2011 RAS was proud to introduce their latest Easy Fit kit. Although these kits do what the previous kits do, the main benefit is ease of installation, taking approximately one hour to install. Without having to interfere with U bolt or nuts.Buy Now
In 1996, a Charlotte, North Carolina engineering company perfected a one-of-a-kind read leaf spring product for vehicles with rear leaf spring suspension – pickup trucks and SUVs.
This product had to not only assist in additional load carrying, but also greatly improve road handling, ride quality, eliminate axle wrap and wheel hop, and to make the vehicle safer.
