How these guides are put together

Each guide starts from published sources, not impressions. We read manufacturer documentation — fitment charts, torque specs, warranty language — and put the numbers side by side, naming where each figure came from.

Nothing here is presented as a dyno result or a measured figure unless the source is cited on the page. Where a claim cannot be verified from a primary source, the guide says so rather than repeating it as fact. Most parts content repeats manufacturer marketing as though it were independent testing; that is the difference worth paying attention to.

What you’ll find

Fitment and buying guides — offset, load rating, spring rate, pad compound, exhaust diameter. The numbers that decide whether a part works, explained without the marketing layer.

Install reality — what the documentation does not tell you: seized hardware, steps that assume a lift, torque values that differ between the manual and the forum. The part that determines whether a job takes an afternoon or a weekend.

Spec comparisons — published figures side by side, with the source named on the page.
