About WrenchConnected
WrenchConnected is an independent installation marketplace operating in partnership with Diesel Power Products.
How it works
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
Pricing
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
Your privacy
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.
