Trailing arm blocks are used for those raising their suspension by 2" or more. It goes between the TA mount & the chassis rail to maintain the correct rear wheel position & the arc it follows as the suspension articulates.
Most TA blocks on the market are individual blocks, one with 2 holes (rear) & one with one hole (front). The trouble with this is under heavy loads like hitting a pothole, speed hump, rut or dropping a spinning wheel, these individual blocks rock back & forth, causing metal fatigue in the rails. There have been examples of bad cracks & one where the captive nuts were ripped out through the rail! Thats a catastrophic failure!!!
By welding the blocks together, this "rocking" is eliminated, also any shearing force is spread more evenly across the 3 bolts.
I also put end plates on the blocks (others are open ended) to further strengthen them & to keep mud out & help prevent rust
They also have crush tubes...I cant believe some kits dont have crush tubes!
A set (left & right) of TA blocks after welding, ready for cleaning up & painting
