Review on ACDelco Professional 45H1203 Rear Coil Spring Set: Reliable Suspension Upgrade for Optimal Performance by Dang Reid

Let me start by saying that Revain's cross reference/search is not accurate on this part. This is not an OEM part. After calling ACDelco to ask them why there was such a drastic change to the part, they basically told me it was an aftermarket part and using 10 different searches under the Toyota 3.3L V6- engine is compatible. This spring is much longer and thicker than the original spring on my van, so much so that the rear of my car is about 33 3/4 inches from the ground to the highest part of the wheel arch, while my front end with brand new suspension parts is about 29 and 1/4 inch from floor to highest part of wheel arch. The car is very unstable and this part is definitely not compatible with the 2005 Toyota Sienna XLE limited front wheel drive 7 seater configuration. To figure out how to return a part that my auto loans can forgo until a new kit is available and figure out how to deal with the store's labor replacement fee.
