*Freight includes shipping BOTH ways and it must be a commercial address with a forklift
We build a complete transmission that is ready to bolt in and go. All of our Allisons are built the same (clutch pack stackup) whether you're looking for a 1000+RWHP truck or you're looking for a reliable transmission for your 500HP daily driver. Our transmissions have been in multiple trucks well over 1000+RWHP with lots of abuse drag racing, dyno runs and sled pulling all on the same build for a full season. We set them up according to your predicted power level and we can add billet shafts/hub, C3 PTO oiling holes or a pan for the cost of parts. It is preferred to use your current transmission that is in your truck but we do have cores on the shelf which we can build to order.
