Harley-Davidson X440T Rear Shock Absorber Pair Pearl Red HDHR4AAC3J0010ARGS | Genuine Twin Rear Suspension Set

Harley-Davidson X440T Rear Shock Absorber Pair – Pearl Red – HDHR4AAC3J0010ARGS

Genuine twin rear suspension set for the Harley-Davidson X440T. Part number HDHR4AAC3J0010ARGS is identified in the supplied X440T R4AA catalogue as CUSHION REAR ASSY (PEARL RED). In normal buyer language, this is the rear shock absorber pair, rear suspension set, rear twin shocks, or rear cushion assembly for the X440T.

This listing is sold as a SET OF 2 rear shock absorbers. The X440T uses a twin-shock rear suspension layout, so this product is packaged and sold as the complete left + right rear shock pair rather than as a single shock.

This listing targets the search terms X440T owners and workshops actually use: Harley X440T rear shock absorber, X440T rear suspension, Harley X440T twin shock set, X440T rear shock pair, X440T genuine suspension, X440T Pearl Red rear shock, and the exact SKU HDHR4AAC3J0010ARGS.

Important: This Listing Is for X440T Owners

This is the X440T-specific Pearl Red rear shock absorber set. It should not be ordered merely because you own a Harley-Davidson X440-series motorcycle.

If you own the standard Harley-Davidson X440 or X440 OBDII and need the earlier Force Silver rear shock absorber pair, use our separate X440 listing:

Harley-Davidson X440 / X440 OBDII Rear Shock Absorber Pair – Force Silver – HDH52400RAA001AS

Keeping the X440T and earlier X440 suspension listings separate helps prevent customers from ordering by appearance alone and receiving the wrong finish or generation-specific part.

Fitment is intentionally kept conservative. The supplied X440T catalogue confirms this exact SKU for the January 2026 X440T application. We are not treating this Pearl Red X440T part as automatically interchangeable with the standard X440 or X440 OBDII suspension.

Factory Suspension Context

Official Harley-Davidson / Hero specifications for the X440T describe the rear suspension as gas-charged twin shocks with 7-step preload adjustability. The owner's manual also instructs that the left and right rear shock absorbers should be adjusted equally.

That is one of the reasons this product is being sold here as a matched set of 2: both rear shocks work together as the motorcycle's rear suspension pair.

Why Replace Both Rear Shocks as a Pair?

• Helps keep damping behaviour consistent from left to right
• Maintains equal preload adjustment on both sides
• Avoids mixing a new shock with an older worn shock
• Useful when restoring the motorcycle after accident or suspension damage
• Preserves the intended Pearl Red appearance on both sides
• Makes it easier to restore balanced rear suspension behaviour

When Should Rear Shock Absorbers Be Replaced?

Rear suspension should be inspected if you notice any of the following:

• Oil leakage from a rear shock absorber
• Rear of the motorcycle feels unusually bouncy
• Rear suspension feels weak or poorly controlled over bumps
• One shock appears to sit differently from the other
• Visible bend, dent, impact damage or damaged mounting eye
• Abnormal noise from the rear suspension
• Corrosion or physical damage affecting the shock body or spring
• Motorcycle has suffered an accident or heavy rear-side impact

What This Part Does

The twin rear shock absorbers control the movement of the rear swingarm and help manage spring movement as the motorcycle travels over bumps, braking loads and road undulations. The spring supports the motorcycle and load, while the damper controls how quickly the suspension compresses and rebounds.

Correctly functioning rear shocks therefore contribute to:

• Rear-end stability
• Controlled rebound after bumps
• Better tyre contact with the road
• Predictable handling
• Rider and pillion comfort
• Proper suspension response under varying loads

7-Step Preload Adjustment

The X440T rear twin-shock system provides 7-step preload adjustment. Preload changes the spring's initial compression to suit load conditions; it does not turn a damaged or worn shock into a serviceable one.

When adjusting preload:

• Both rear shocks should be kept on the same setting
• Use the correct adjustment tool
• Select the setting appropriate for rider / pillion / luggage load
• Do not intentionally run mismatched left and right settings

Pearl Red Finish – Check Before Ordering

This SKU is listed in the X440T catalogue specifically as CUSHION REAR ASSY (PEARL RED). The finish is therefore part of the product identity, not just a generic description.

If your motorcycle requires a different rear-shock finish or you own an earlier X440 / X440 OBDII, use the appropriate model-specific listing instead of ordering based solely on shock shape.

Difference from the Earlier X440 Rear Shock Listing

We already stock and list the earlier Harley-Davidson X440 / X440 OBDII rear shock absorber under a different part number and finish:

• X440 / X440 OBDII: HDH52400RAA001AS – Force Silver – separate listing
• X440T: HDHR4AAC3J0010ARGS – Pearl Red – this listing

Do not use these two SKU references interchangeably unless an official supersession or cross-fitment is documented.

Installation & Pre-Fitment Inspection

• Compare the supplied SKU with the required motorcycle catalogue before installation
• Inspect upper and lower shock mounting points for bending or damage
• Inspect swingarm alignment if the motorcycle has been in an accident
• Install both shocks as a matched pair

Safety Note

Rear suspension directly affects motorcycle stability and handling.

Professional installation is recommended where accident damage or suspension misalignment is suspected.

Use our separate X440 / X440 OBDII Force Silver rear shock absorber listing rather than this X440T-specific listing.

This product is sold as a pair. Using two matched units helps keep the rear suspension consistent from left to right.
