TMR Customs Lifetime Heims are a premium rod end that will last you a lifetime of abuse! They are 100% manufactured in house under the most strict quality controls. 
Lifetime Heims are greaseable, sealed and fully rebuildable. They are intended to be serviced after years of operation and every individual part is available to rebuild them to factory spec. 
Lifetime Heims have the strength and misalignment you want from a chromoly rod end - paired with the greaseability and serviceability you expect from a Johnny Joint. 
Lifetime Heim bodies and spanner nuts are machined from heat treated chromoly. The ball is machined from heat treated stainless steel and the races are made from a proprietary blend of bearing grade bronze. All together they make the toughest and most durable heim on the planet!
