These are brand new, replacement bushings for the hairpins, 4 bars, coil over shocks, and panhard bars on your hot rod. I have both FRONT (1/2" deep) and REAR (3/4" deep) bushings. You MUST specify FRONT or REAR bushings when ordering! Made from black, 90 durometer, urethane. They will replace the bushings in the hairpins, 4-bars, and adjusters of your Ch***is Engineering, Deuce Factory, Magnum Axle, Pete & Jake's (front only, not rear), So-Cal Speed Shop, and Total Cost Involved (TCI), suspension bars. Can be used to replace many of the panhard bar bushings from these companies as well. Can also be used in the Spax coilover shocks sold by the Deuce Factory, and Ch***is Engineering. (Will not replace the bushings in Aldan Eagle coilover shocks.) (Will not replace the REAR bushings in Pete & Jake's REAR bars.) Price is for two bushing halves, making one complete bushing. So, you will need eight (8) to do a complete 4-bar kit, or four (4) to do a pair of coilover shocks, or (2) to do a panhard bar. Shipping cost is $4.00 for the first bushing, and .50 additional for each one after that. (example: 8 bushings would be: $4.00 + $3.50 (7 x.50) = $7.50 total) Please Paypal at: docktor32@hotmail.com (The term 4-bar is a trademark of Pete & Jake's Hot Rod parts.)
