    Increase Overall Vehicle Stability and Handling Performance

    Roadmaster's Active Suspension System is the only leaf spring support that converts a vehicle's "passive" leaf spring suspension into "active" mechanical suspension. The Roadmaster System is equipped with springs that instantly absorb shock and dissipate load force energy. With or without a load in your vehicle, the results of using Roadmaster are greatly improved vehicle stability, balance, traction, and control.

    Roadmaster Active Suspension adds critical strength to leaf springs without deteriorating ride quality. The patented design prevents bottoming out, axle wrap, and wheel hop. This also improves handling by reducing sway and body roll while cornering and beefs up rear leaf springs for hauling with maximum safety. Vehicles consistently operating under load, hauling, or towing benefit from better fuel economy and load-carrying capacity. In addition, tire wear and suspension damage are reduced. Once installed, Roadmaster Active Suspension requires zero adjustment or maintenance.

    Features
  • Attaches Directly to Rear Leaf Springs
  • Increases Vehicle Stability, Especially When Towing or Hauling
  • Never Needs Adjustment or Maintenance After Installation

    4611 - Roadmaster Active Suspension Kits is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from performance really surprised me. installed month ago -- okay put this on 2011 chevy 1500 Silverado 6.5 bed and bed had tonneau cover. first side took probably took 45 min as I was triple checking everything. Second side counting taking tire off and putting back on 20 minutes. I just jacked up one side at a time. I set the gap for 1mm as the load I was wanting to carry was atv in truck bed and Aliner camper hooked up (2000 lbs) Tongue weight was 280 lbs, atv (can-am 650 max) 900 lbs. the back wheels of atv set just on beginning of tail gate. Before suspension installed measured at top of 2" hitch bar empty;18.5" atv;15" atv+trailer;14.5" After installation empty;19.25 atv;15.25 atv+trailer; 14.75 I would buy this product just for the handling of the empty truck. Very noticeable improvement when stopped and making a hurried right turn into curb lane, went around corner like a car. Also when empty on dirt road with washboards for 1/2 mile it seemed to handled them much better. Felt there was slight improvement with atv+trailer, did seem to take bumps better. As you know, almost any product that you put on your truck the manufacturer will claim better gas mileage. Just finished a 500 mile trip with truck empty could not believe the average mileage was 20.1 the most I've gotten before was high 18's. Don't know if it was a quirk or what so take this with grain of salt as it was just one trip. I'm not a lead foot nor a light foot. I did take a 200 mile trip with atv+trailer but hard to say if mileage was better as atv sticks above cab roof and mileage has varied even before installation. There you have it, bottom line -- this is one of first things I would put on a 1/2 ton truck. For the 3/4 and 1 ton someone else will have to do a review as this review is strictly for 1/2 ton.
