Famed inconel radius / trailing arm bolts, supplied as a pair, complete with 2 new Nyloc nuts (don't reuse old ones). These bolts use a "fine" thread, which is different to the original thread.
Where the trailing arms meet the frame there is a bushing and a bolt that goes through the frame/bushing and the trailing arms - these are called the rear suspension trailing arm bolts (TABs), which is also where you can make the adjustment to set the rear alignment on the car using shims. The stock bolts have a tendency to get loose and when they get loose they will bend and eventually can break which can be very dangerous. The bolts are also subject to corrosion which can freeze the bolt into the arm and weaken the bolt.
These bolts are made from the super-alloy "718 Inconel", which is corrosion resistant and developed for use in highly corrosive environments where intense strength is also needed.
As well as replacing the shims with our stainless ones, you might want to consider new washers. Each side uses 1 x SP10868, 2 x 101935 and 1 x 106962.
