TR4A remanufactured Chassis unpainted Left hand side view (IRS version shown for reference)

TR4A Rigid axle Remanufactured Chassis Frame sold on an exchange basis, untreated, using a combination of new and original second hand parts where they are in good enough condition, typically rear hump, rack supports and turrets, taken from your chassis or our stock.

We offer a comprehensive chassis service supplying complete chassis in a variety of finishes and also supplying individual chassis parts, many of which were not available originally as separate items.

The chassis can be supplied: -
  • Unpainted. 
  • Etch primed only.
  • Etch primed and painted black.

TR4A-6 chassis are supplied on an exchange basis completely remanufactured. We use as a minimum the steering rack mounting cross brace and brackets, the main turrets and rear hump along with other small parts from your chassis for inclusion in the remanufactured chassis build. More information about this process can be found HERE.

It is therefore imperative that these parts are returned to RevingtonTR when ordering a remanufactured chassis.

Should you choose to take your remanufactured chassis away prior to returning your old chassis, a deposit RTR7286 will be charged until usable parts as detailed above are returned to us.

NOTE: All TR4A‑6 chassis incorporate our front suspension and differential support (not live axle)  strengthening modifications, as the standard chassis is weak in design in these areas.

Be aware that there are slight differences between the differential mountings to TR4AIRS cars and TR250, 5 and 6. The differential support pins protrude downwards 57mm on TR4A cars and 62mm at  the back on TR6 cars, as the rear mounting arrangement is different between the two cars. Therefore a TR4A chassis cannot be used for a TR250-6 unless the engine mount and the differential mounts are changed.

Please remember that chassis ordered under this part number will be supplied in bare steel as taken out of the assembly jig with no treatment at all, Revington TR offer the treatments below.
The photographs show a TR4A IRS (for reference) chassis just taken out of the jig and on it's way to shot blasting prior to painting.
