We recommend that this be installed by a qualified mechanic with experience doing this type of work. Our kits come standard with parts from the best names in the industry, and we stock the exact same parts from different manufacturers. We do this so that when back orders occur like they have been for the last year we have an alternate part to send that is the same quality. This would be the ONLY reason your order might be slightly different when it arrives.
99% of problems can be easily solved without returning the entire order. Orders must be sent back 100% complete and all parts brand new, never installed, in the original packaging. Once items have been installed or used in any way they are not eligible for return. This product is NOT DIY. Over 99% of people in the world are not qualified to build an engine. It has to be done 100% correct, and many parts must be measured down to the. We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic. It is the responsibility of the person assembling and tuning the parts to make sure they work correctly. 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.
