I replaced the entire front suspension except for the stock Billstein struts. I still have these on my 2007 Dodge Magnum SRT8 with 116,000 miles. Maintenance grease and rubber bushings are thicker and fit perfectly on upper control arm, upper ball joint, lower outer control arm, lower outer ball joint, lower inner control arm, made by Scitoo, they fit perfectly on my SRT8, time will tell which brand lasts longer than others , but my knocks, pops, bumps, fender skin chafing, scratches and overall rough ride on my 22" rims are gone without replacing the stock Billstein struts. This is a great price for all these parts and they fit my srt8 perfectly
