Eight steps from today’s suspension to a plan you can keep. Leave anytime: your place saves with the plan.
The steps
- 1
Suspension today
What’s on the truck today?
Lift, shocks, bumpstops and the travel and ramp score they give are the baseline. Where nothing is saved for your truck, the factory figures on file stand in, labeled.

Lift and springs
How much lift, and on which springs?
Springs set ride height and where the wheel sits in its travel. Lift alone doesn’t add travel; it moves where the travel sits.

Shocks
Do the shocks have the stroke?
Shock stroke caps travel. A shock sold for less lift tops out early and becomes the droop limit.

Bumpstops and limit straps
What stops each wheel?
Bumpstops set full stuff and keep the tire off the body. Limit straps set full droop before the shock or the coil does. Suspension shows which one stops each wheel first.

Links and arms
Do the links and arms let it flex?
Links shows link angles and anti-squat after the lift. Suspension lists the arms and links that fit your truck and says when a joint binds before the travel runs out.

Sway bars
Disconnect the sway bars?
A connected bar holds one wheel back while the other drops. Suspension shows what a disconnect or a softer bar adds to the ramp score, and what it does to roll on the road.

Tire clearance at full stuff
Does the tire clear at full stuff?
More up-travel brings the tire closer to the fender and the body mounts. Suspension draws each wheel at full stuff; Clearance measures the truck as it sits. A rub nobody has checked stays an open check.

Review
Review and keep
Travel and the ramp score before and after, what changed against Actual, and the open checks.
Each step opens a calculator with your truck filled in. Most of them are Suspension: springs, shocks, bumpstops, limit straps and sway bars, with the travel and ramp score they give. Links covers link geometry after a lift, and Clearance measures the truck as it sits. With JavaScript on, this page keeps your place and your answers in My garage.
More flex, answered
Does a lift add wheel travel?
Not by itself. A lift moves where the wheel sits in its travel. Travel ends at whichever limit comes first: the shock bottoming or topping out, a bumpstop, a limit strap, or a joint running out of angle. Suspension names the limit at each corner, so you can see which part to change.
What does the review compare?
Wheel travel and the ramp score (RTI) before and after, next to the lift, the parts, the sway bars and roll on the road. Before is what’s saved for the truck, or the factory figure on file, labeled as such. A figure nobody has worked out stays unknown.
Should I disconnect the sway bars?
On the trail, a disconnect lets each wheel drop further. On the road, the bars are a big part of what keeps a loaded truck composed in a lane change. Suspension shows both sides of every bar choice: its ramp score, and roll per g against stock.
Use at your own risk. These calculators are here to help you plan and to inform your decisions, not to sign off on a build. Many numbers are estimates worked out from factory figures, and some factory figures are not yet confirmed. Check every number against your own truck, its manuals and a qualified shop before you buy parts, cut, weld, lift, regear or drive on it. Long Range Desert Tools is not liable for anything you do based on these calculators or their results. The full terms are in our policies.
