TMB Sirris R38 Linkage | Arctic Leopard XE Pro S, Enduro, XE Pro R, & Vetra Blazer

The TMB Sirris R38 Linkage is a purpose-built suspension component designed specifically for installing the Sirris R38 rear shock on Arctic Leopard XE Pro S, Enduro, and XE Pro R electric dirt bikes.

The Sirris R38 uses a much larger, performance-focused shock design than the factory Arctic Leopard rear shock, so the stock lower linkage cannot be reused. TMB Motorsports developed this linkage to provide the proper mounting configuration for the R38 while adding the strength and durability needed for aggressive riding.

Required for Sirris R38 Installation

Important: The stock Arctic Leopard lower linkage is not compatible with the Sirris R38 shock. This TMB linkage is required when installing an R38 on the compatible Arctic Leopard models listed below.

The TMB R38 linkage is also not compatible with the stock Arctic Leopard rear shock. It is designed specifically around the Sirris R38 shock.

CNC Machined for Strength & Durability

Precision CNC machined by TMB Motorsports, the linkage uses billet aluminum construction to provide a strong and precise connection between the R38 shock and the Arctic Leopard rear suspension system.

• Construction: CNC-machined billet aluminum
• Bearings: Oversized premium bearings
• Finish: Hard-anodized protective coating
• Lubrication: Factory-applied waterproof grease
• Shock Compatibility: Designed specifically for the Sirris R38 rear shock

The oversized bearings and waterproof grease are particularly useful for bikes that regularly see dirt, mud, water, and repeated suspension movement. Combined with the hard-anodized finish, the linkage is built for long-term use in demanding trail, enduro, and off-road conditions.

Fitment

• Arctic Leopard XE Pro S
• Arctic Leopard XE Pro S Enduro
• Arctic Leopard XE Pro R
• Required Shock: Sirris R38 rear shock

Compatibility Warning: This linkage does not work with the stock Arctic Leopard rear shock. The stock Arctic Leopard lower linkage does not work with the Sirris R38. The TMB R38 linkage and Sirris R38 shock are designed to be used together.

Who Is This For?

• Arctic Leopard riders upgrading to the Sirris R38 who need the correct lower linkage for installation.
• Enduro and aggressive trail riders building a stronger, more capable rear suspension setup.
• Performance-focused builds pairing the Sirris R38 rear shock with upgraded suspension such as the Sirris F43 CMX fork.
