WrenchConnected is an independent installation marketplace operating in partnership with Diesel Power Products.
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.
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.
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.

"Worth every penny! This product does what it says it will do."
"Helps the shifting"
"My truck is mostly stock and haven't done much hauling yet, so I haven't noticed any difference."
"I just added Hot Shot's Secret Shift Restore. Leaving today for a long trip pulling a heavy trailer over passes. Just trying to ease the strain on the tranny. Will let you know!"
"Used some in both the transmission and transfer case, haven't noticed a bigger difference yet. But long run I imagine it works the great."
