Poly coil spring spacers for a Jeep wrangler TJ ( 97-06 ) are exactly the same as the 3/4 and 1" poly spacers just to give you a few more options for shopping. I bought 3/4" from TGC. I thought they looked familiar so I checked my assortment of Jeep spacers and matched perfectly. I eventually swapped the 3/4" for a pair of TJ 1" spacers I had and have been just fine .
