Bring your car back to life, or ensure that it stays on the road with this ultimate timing chain service kit by AMTuned. No more piecing things together from various places only to pay a ridiculous amount and encounter missing items when doing the service. Our ultimate timing service kit contains all the replacement parts needed to correctly perform the service. Customers must select their remachined sprocket core option or the AMTuned rebuilt adjuster option from the drop down menu. If you want your kit to ship out right away, the refundable sprocket core option of $100 must be selected. There is a secondary option for valley pan kits. Sprocket core's are refundable for up to 30 days after your order is delivered (Your core's need to be in the mail within 30 days of delivery). We use electronic solenoids that do not have an incorporated pigtail, we supply a plug and play extension harness for bank 2 which the stock harness will not reach.
