Ask any fleet mechanic who keeps classic KAMAZ trucks on the road which suspension part they order most, and the torque rod 1630-2919010-20 (Russian: тяга реактивная, "reactive rod") will be near the top of the list. It is a 13 kg steel link that lives a hard life under the rear bogie — and when its rubber-metal hinges wear out, the whole rear suspension geometry goes with them. This guide covers what it does, which trucks it fits, and how to spot a worn one before it takes out your tyres and springs.
What the torque rod actually does
On a KAMAZ rear bogie, the leaf springs locate the axle vertically — but they were never meant to absorb the longitudinal and twisting forces of driving and braking. That job belongs to the torque (reactive) rods:
- They connect the rear-bogie axle beams to the frame
- They take up longitudinal and reactive (torque) loads, relieving the springs of driving and braking torque
- They keep the axles aligned so the prop shafts, tyres and spring eyes are not fighting the geometry
The rod is built with rubber-metal hinge joints (RMSh) at its eyes — silent-block style bushings that allow articulation while isolating vibration. Those bushings are the wear item: heat, oil contamination, overloading and age all crack and separate the rubber.

Which trucks does it fit?
One rod covers seven of the most common KAMAZ models:
- KAMAZ-5320 — the classic 6x4 flatbed
- KAMAZ-53212 — long-wheelbase 6x4
- KAMAZ-5410 / 54112 — 6x4 tractor units
- KAMAZ-5511 — 6x4 dump truck
- KAMAZ-55102 — agricultural dump
- KAMAZ-65115 — the modern 6x4 dump still in production
That fitment spread is why this rod is a staple of any KAMAZ spare-parts stock: the 5320/5410/5511 family plus the 65115 covers decades of production still working across Russia, Central Asia, the Middle East and Africa.
Symptoms of a worn torque rod
Catch it early and you replace a rod; catch it late and you replace tyres and spring eyes too:
- Uneven or accelerated rear tyre wear — the axle is no longer held square
- Clunking from the rear bogie when pulling away or braking — worn RMSh bushings letting the eye move
- Visible cracking or rubber separation at the rod eyes, or the rubber pushed out of centre
- Axle misalignment — the truck dog-tracks or the prop shaft angles look wrong
A practical check: with the truck loaded, look at the rod eyes. Fresh bushings sit centred; worn ones show the inner sleeve off-centre or rubber extruded.
Before you order
- Match the catalogue number 1630-2919010-20 against your parts book or the old rod.
- Buy in pairs where possible — if one side's bushings are gone, the other side has lived the same life.
- For wholesale orders, remember torque rods are heavy (13 kg each): they ship efficiently as mixed pallets with other suspension items.
