Question:
Product number number TRA 15252 Timbren suspension enhancement system. am I accurate to believe that the rubber spring is 4 inches tall the directions say you need four and three-quarter but does that number come in to play because of the brackets are 3/4 of an inch high the rubber Spring itself is 4 inches?
asked by: Richard W
Expert Reply:
Yes, that all sounds accurate Richard. I checked with Timbren and the spring on their Trailer Suspension Enhancement System item # TTRA15252 measures 4" tall without weight placed on it. The spacers and plates add up to right below 3/4".
