At bpratv our kits come with the same brand name parts as other rebuild kits you see online but we always include items no one else does. This would be the ONLY reason your order might be slightly different when it arrives. Please check your order completely right when you receive it and let us know immediately if there is an issue, that way we can fix it for your ASAP.
99% of problems can be easily solved without returning the entire order. Once items have been installed or used in any way they are no longer eligible for return. We stand behind all parts we sell 100%. Most products we sell ARE NOT DIY.Assembling and tuning an engine is not easy and it has to be done EXACTLY RIGHT. We send an instruction sheet with our kits that lists the steps for assembling an engine and you must follow EVERY SINGLE STEP, and do so correctly. STRONGLY recommend parts be installed by a qualified, experienced mechanic.
The person who installs the parts we sell takes on a large responsibility for them working properly. Also, we want information from customers when their experience is less than desirable so we know what areas need improvement the most. Please work with us and we will ALWAYS work with you.
