Endurance S330100803 Gas Rear Shock Absorber Set – Royal Enfield Bullet (Old)

Endurance S330100803 is the aftermarket/OE-vendor gas-charged rear shock absorber listed by Endurance for Royal Enfield Bullet (Old). This Under The Hood listing is sold as a complete pair of 2 shock absorbers for the left and right rear suspension positions.

The actual stock photographed by Under The Hood has a black coil spring, chrome upper cap and damper tube, and silver/grey lower body with external gas chamber.

Exact Product Details

Why This Listing Is Different From a Single Rear Shocker

Royal Enfield twin-shock motorcycles use two rear suspension units. Replacing only one worn shock can leave one side with an old damper and the other with a fresh damper.

This product is therefore sold by Under The Hood as a matched 2-piece replacement set:

• 2 × Endurance S330100803 gas rear shock absorbers
• One complete pair for the rear suspension
• Same part number and finish supplied as a set

Manufacturer-Verified Application

Endurance's own two-wheeler shock absorber catalogue lists:

S330100803 – Shock Absorber Gas – Suitable For: Royal Enfield Bullet (Old)

Endurance aftermarket price lists also describe the same code as:

S/A REML BULET GAS (OLD) / Rear Shocker Gas Bullet 350cc Gas O/M.

The physical box supplied to Under The Hood carries the matching description S/A REML BULLET GAS (OLD).

What Does “Bullet (Old)” Mean?

Endurance uses Bullet (Old) / O/M (old model) as the application wording for S330100803. Buyers commonly search this category as:

• Royal Enfield Bullet old model rear shocker
• Bullet Standard old model shock absorber
• Bullet 350 old gas shocker
• Royal Enfield old Bullet gas shock absorber
• Bullet Standard BS3 shocker
• Old Bullet short gas shocker

Because Royal Enfield used multiple chassis, engines and rear-shock versions over many years, the safest purchase check is the old shock / Endurance part number / exact model-year configuration. Do not rely only on the words “Bullet 350”.

Important: Endurance Makes Several Different Royal Enfield Shockers

This is where many incorrect online listings go wrong. Endurance has separate catalogue numbers for different Royal Enfield applications.

Do not substitute these numbers only from colour or appearance.

Why Do Some Websites Call S330100803 an Electra Shocker?

Some third-party sellers currently list S330100803 under older Electra 4S/5S applications. However, Endurance's own catalogue and the physical box supplied to us identify this exact code as Bullet Gas (Old). For return prevention, Under The Hood follows the manufacturer/box identification as the primary fitment.

If your motorcycle is an Electra and the removed shock is stamped / boxed as S330100803, contact us or compare the old unit before ordering. Otherwise, use the correct Electra-specific Endurance part number.

Actual Finish of the Stock Shown

The product photos on this listing show the actual current Under The Hood stock:

• Black coil spring
• Chrome upper cap
• Chrome centre damper tube
• Silver / grey lower cast body
• External gas chamber / reservoir-style body
• Preload-adjuster collar visible on the supplied shock

Finish can change across manufacturer production batches, so the part number S330100803 remains more important than colour alone. The photos are the best reference for the stock currently being sold.

Gas-Charged Twin-Shock Design

Endurance classifies S330100803 in its gas shock absorber range. The shock combines a coil spring with hydraulic damping and a gas-charged damper design.

A good rear shock helps control spring movement after bumps so the motorcycle does not continue bouncing excessively. It also contributes to rear-wheel control during braking, cornering and uneven-road riding.

When Should Rear Shock Absorbers Be Checked?

Have the rear suspension inspected if you notice:

• Excessive bouncing after a bump
• Rear end feels unstable or wallowy
• Shock absorber leakage
• Rear suspension has become unusually harsh
• Bike sags excessively with rider/pillion
• Knocking or clunking from the rear suspension
• Bent or damaged shock after a fall
• Uneven behaviour between the left and right sides

These symptoms do not automatically prove the shock absorber is the only faulty part. Swingarm bushes, wheel bearings, tyres and shock mounting hardware should also be checked.

Why Replace as a Pair?

If both existing shocks have similar age and mileage, replacing the pair together is generally the cleaner repair because the motorcycle then has two fresh units rather than one new damper paired with one worn damper.

This listing makes that easy by supplying 2 pieces as one set.

Endurance vs Royal Enfield-Branded Packaging

Endurance is an established two-wheeler suspension manufacturer and supplier to major vehicle manufacturers. This product is supplied in Endurance aftermarket packaging; it is not being sold as a Royal Enfield-branded boxed spare.

If you specifically want a shock absorber in Royal Enfield Genuine Parts packaging, Under The Hood also stocks genuine Royal Enfield rear shock options. Match the exact Royal Enfield part number and model before buying.

Already Looking for the Classic / Electra Endurance Shocker?

Under The Hood also has a separate Endurance rear-shock listing for Classic 350 / Electra 350 BS3/BS4. That product should not be confused with S330100803 just because both are Endurance gas shocks.

Before You Buy – Return Prevention Checklist

• Confirm Endurance part number S330100803
• Confirm your application is the older Royal Enfield Bullet / Bullet Standard type
• Compare the removed shock and mounting style
• Do not buy for J-Series Bullet 350 (2023+) – completely different platform
• Do not buy for Classic 350 Reborn / Meteor / Hunter / 650 models
• Do not assume Classic / Thunderbird / Electra fitment merely from similar appearance
• Remember: this listing contains 2 shock absorbers

Installation Notes

Rear suspension affects vehicle stability. Installation by a competent motorcycle technician is recommended.

• Support the motorcycle securely before removing the rear shocks.
• Inspect upper/lower mounting bolts and bushes.
• Inspect swingarm play and rear-wheel bearings.
• Fit both shocks without forcing misaligned mounts.
• Use correct Royal Enfield torque specifications for the exact model.
• Set spring preload equally on both sides if adjustment is used.
• Check tyre clearance, chain clearance and suspension movement after installation.
• Road-test carefully before normal use.

Buyer FAQs

Is this one shock or a pair?
Pair of 2. Under The Hood sells this listing as a complete 2-piece rear shock set.

What is Endurance S330100803?
It is Endurance's gas rear shock absorber for Royal Enfield Bullet (Old).

Does it fit Royal Enfield Bullet Standard?
S330100803 is manufacturer-catalogued for the old Bullet application and is commonly sold for older Bullet Standard setups. Because Standard models span many years and suspension changes, confirm your old shock / part number before ordering.

Does it fit the new Bullet 350 J-Series?
No. The 2023+ J-Series Bullet 350 uses a different rear-suspension platform.

Does it fit Classic 350?
Do not assume so. Endurance lists separate part numbers for Classic 350 applications. Use the exact Classic-specific shock listing for your model.

Does it fit Electra?
Some third-party sellers map S330100803 to older Electra variants, but Endurance's own catalogue and our current box label identify it as Bullet Gas (Old). Verify the old shock before using it on an Electra.

What colour is the current stock?
The photographed current stock has a black spring, chrome upper/centre sections and silver/grey lower body.

Is it gas charged?
Yes. Endurance catalogues classify S330100803 as a gas shock absorber.

Is this genuine Royal Enfield?
No. This listing is for a genuine Endurance product in Endurance packaging. Endurance is an OE/OEM-vendor-level suspension manufacturer, but this should not be represented as a Royal Enfield-branded boxed spare.

Do you also sell Royal Enfield original packaging?
Yes, Under The Hood stocks genuine Royal Enfield rear shock absorbers separately. Match your Royal Enfield part number and exact model before ordering.

What MRP is printed on the current box?
The current 06-2026 stock photographed shows ₹1,361 MRP per shock. This listing contains two shocks, so the combined printed MRP is ₹2,722.

Why should I replace both rear shocks together?
If both shocks have similar age/wear, replacing the pair helps avoid combining one fresh damper with one worn damper. This listing is therefore supplied as a complete set of two.
