TR4AIRS Rear bridge assembly (comprising 1 x 214031 cross member, 2 support 141793 for the rear dampers, differential support brackets 140051 and pins 147671). This assembly is NOT suitable for TR250, 5 or 6 as the differential location pins are a different length. These cars use RTR7004-1.

 
The TR4AIRS and TR250, 5 and 6 rear bridge differ only in that the location pins for the rear differential supports are at different heights due to the  variation in rear diff. mounting.
TR4AIRS = 57mm
TR250. 5, 6 = 62mm
This is measured from the support bracket to the end of the plain section pf the pin, excluding the threaded portion.

This is a fully assembled component, fully welded and ready to install. 
When fitting this assembly be sure to fit strengthening kit RTR7012-1K or RTR7012-2K as the design is inherently weak, a situation which is completely cured by either one of these kits.
 
We also offer second hand original bridges RTR7004SH and RTR7004-1SH that are serviceable and have been removed from chassis with rotten main rails. Ideal for the concourse original look.
 
Owners of TR4A live axle cars should purchase the specific parts required as there are only two part numbers, the cross member and the damper brackets.
