Estimate bump travel, droop travel, and wheel movement from shock stroke and motion ratio with this fast, mobile-friendly suspension calculator.

Find your wheel bolt pattern fast. Convert lug pattern sizes between mm and inches and match common equivalents like 5×114.3 and 5×4.5.

A DIY winch mount only works if it sends load into the frame, keeps the fairlead aligned, and stays flat under pull.

Compare vented rotors, brake ducts, and heat shields to fix brake heat based on use: capacity, airflow, or protection for off-road rigs.

Measure bump and droop limits, then size shocks, bump stops and limit straps so stock control arms deliver safe, repeatable front wheel travel.

Disc vs drum brakes for off-road: discs shed heat and water faster and offer better control; drums save space and cost for light-use rigs.

Compare lockers, limited-slip, and selectable lockers for off-road use—tradeoffs in traction, steering, tire wear, and upgrades.

Choose springs from actual loaded weight, wheel rate, motion ratio and use; tune ride height with preload, damping and repeatable test loops.

Match tread to the terrain you drive most, balance on-road comfort vs off-road grip, and confirm fit and load.

Set caster first, camber second, then toe; inspect components, match tire pressure, and tune alignment for desert, rock, or overlanding.
