Cush Rubber (Cush Drive Rubber / Sprocket Carrier Damper) for Royal Enfield Himalayan 450 & Guerrilla 450 – RAT00289/D (Rear Wheel)

Royal Enfield RAT00289/D is the rear wheel cush rubber (also called cush drive rubber / sprocket carrier rubber / hub damper rubber). These rubber dampers sit inside the rear sprocket carrier and absorb shock loads from throttle on/off, reducing driveline lash and protecting the hub, sprocket carrier and bearings.

Replace the cush rubbers if you notice clunking/knocking from the rear wheel, jerky throttle pickup, excessive play in the rear sprocket carrier, or uneven chain snatch—especially after monsoon riding, hard touring, or high mileage. Using the correct OEM-spec rubber matters because hardness and shape control how the sprocket carrier seats; wrong rubbers can cause premature wear or a loose feel.

Before you buy: confirm your bike is Himalayan 450 or Guerrilla 450, and match by VIN/parts lookup or a photo of your sprocket carrier + old rubbers to prevent wrong orders.

FAQs 

Q1 (Fitment): How can I confirm RAT00289/D is correct for my bike?
Best method: VIN-based parts lookup shows RAT00289/D. Alternatively, share a photo of your rear sprocket carrier/cush drive pocket and the old rubbers for visual match.

Q2 (Fitment): Does this fit both Himalayan 450 and Guerrilla 450?
Yes—both models are confirmed by dealer listings for this part number. Still verify by VIN/photo if your rear wheel assembly has been swapped or modified.

Q3 (Comparison): OEM vs aftermarket cush rubbers—what changes?
OEM typically matches the intended rubber hardness and profile, which affects carrier seating and driveline feel. Aftermarket may be too soft (play/clunk returns quickly) or too hard (harshness, poor seating).

Q4 (Installation): Any precautions while replacing cush rubbers?
Clean the carrier pockets, seat all rubbers evenly, and check sprocket carrier play before refitting. After reassembly, verify wheel alignment and chain slack. Many workshops replace bearings/seals if wear is noticed.

Q5 (Symptoms): What problems does worn cush rubber cause?
Rear-end clunk on throttle changes, jerky pickup, abnormal carrier play, faster sprocket carrier/bearing wear, and inconsistent chain feel.

Q6 (Returns-prevention): What should I send to avoid ordering the wrong cush rubbers?
Send (1) bike model, (2) VIN last 6 digits (preferred), and (3) photos of the sprocket carrier + old rubbers laid out. If your old part differs, we stop dispatch and re-check.
