Questions

Common Questions

Quick answers before visitors choose a product, service, or next step.

01What do you help with?+

We build custom upgrade kits, check part fit, and give install notes for DIY builders and small shops on each job.

02Do you sell only full kits?+

No. You can order one part, a full kit, or a parts list with notes for your build when you only need a few items.

03Can you check my parts first?+

Yes. Send your model, year, and current parts, and we check fit before you buy more. That keeps bad orders out.

04Do you help during install?+

Yes. We give step notes, answer questions, and flag common trouble spots before they slow you down on install day.

05Can small shops work with you?+

Yes. We plan jobs, match parts, and keep build sheets clear for teams that do repeat installs across the week.

06How fast do you reply?+

Most requests get a reply in one business day, and rush jobs can be handled when parts are ready for the week.
