The Regear Decision System
A regear is the most expensive decision most owners make by forum consensus. Gears, install kits and labor run $1,000–$2,700; choosing wrong costs a second round of all three. The Decision System replaces consensus with your numbers: your rig, your tires, your use mix, your quotes.

Decision Worksheet
Your use mix — daily, trail, rock, tow — weighed against restore-stock math to land on a specific ratio, with the reasoning shown. Not a chart: a verdict for your rig.

Install & Break-In System
The install-day checklist, the locker while-you're-in-there checklist, printable build sheets, and the 500-mile break-in protocol that keeps new gears alive.
What's inside, module by module
1 · Decision worksheet. Enter your platform and current setup, set the tire target, and weight your driving — daily commute, highway trips, trail and overland, rock crawling, towing. The worksheet blends restore-stock math with use-case bias and returns a specific ratio with its crawl, cruise RPM and the reasoning. Print it; it becomes page one of your build sheet.
2 · Axle tables. Per-axle carrier breaks, practical max ratios and strength notes for the Dana, Toyota, Ford and GM axles under the platforms we cover — the reference that decides whether your ratio needs a carrier, thick gears, or a different plan entirely.
3 · Cost planner & quote check. The full cost stack with 2026-typical numbers you can edit: gear sets front and rear, master install kits, labor, lockers, programmer, fluids. Then the quote sheet: paste up to three shop quotes and see them against the planner line by line.
4 · Shopping-list generator. Platform + ratio + locker choice in, exact buy list out — including the carrier flag when your chosen ratio crosses a break on your axles.
5 · Install & break-in system. Locker while-you're-in-there checklist, install-day checklist, printable build sheets, and the 500-mile break-in protocol — heat cycles, speed limits, the fluid change — as checklists that save your progress in your browser.
6 · Speedometer recalibration guide. Per platform: which programmer or procedure, what it costs, and what else the correction fixes (shift points, odometer).
