Shock Tuning Options

Tuning Options

Adventure Tune - For smooth on-road and off-road use. NO TOWING/Heavy Loads without adjusters on the shocks. This is our most popular tune for those wanting a smooth ride for mainly street, with some off-road.

Dual Sport Tune - For vehicles with taller lifts or carrying heavy loads without adjusters. Moderate off-road use.

Trail Tune - For vehicles wanting to drive faster off-road or needing better handling. Great for a more dedicated off-road vehicle.

Tuning Options from AccuTune Offroad are based on several factors including the vehicles weight and terrain preference. Tuning stages start at Street Tune and go up to Trail Tune. Each step up in stage will stiffen the valving resulting in better handling, better off-road capability, and better bottoming control at the expense of comfort, especially on the street. Bigger tires and lower air pressures can compensate for the stiffer valving.

Rear Spring Options

Eibach 1” Most popular choice, works great for stock weight or with up to 250 additional pounds of accessories.
Icon 2” Good option for vehicles looking for more height, with at least 250lb of weight in the back.
Icon 3” Overland Ideal for the ultimate overland vehicle with a tremendous amount of weight in back. This includes large tire carrier, bumper, fuel cans, fridge, tent top etc.

For a 2.5" lifted front and level ride:
1" spring with up to 200 lb
2" spring with 400 lb
3" spring with 650 lb

For a 2.5" lifted front slight rear rake:
2" spring with 200 lb
3" spring with 400 lb

**3" spring not recommended with less than 400 lb of constant weight in the back.
**Approximations, every vehicle is different
