Initially developed for our ATV shock conversion kits made in 2004, we set out to develop the best adjustable shock under $250.

Due to popular demand, we have created the DIAMOND+ model shock with added compression adjustment and a high quality machined body for only $399!

After years of feedback and improvements, we are happy to provide a shock that can be used on ATVs, Motorcycles, and other off-road vehicles to upgrade stock suspension performance.

 

Compatible with our Adult ATV Shock Conversion Kits. (Same size as 400ex stock shocks)

These shocks are adjustable in preload, compression, and rebound:

Preload can be adjusted using included tool to tighten the nut/collar above spring coils.

Compression can be adjusted by twisting the top knob on the reservoir.

Rebound can be adjusted by twisting the bottom knob on the reservoir.

 

Spring Rates:
400mm x 9mm Coils: 146 lbs/in
400mm x 10mm Coils: 212 lbs/in (Sold Separately)

Shock Warranty:
Diamond J Customs will replace any shock components that fail within three months of purchase at no charge. This warranty covers one replacement per purchase.

Shock Bushing Upgrade:
For customers seeking enhanced performance and durability, we offer Delrin shock bushings as an upgrade. These bushings are available for purchase at an additional cost.

*Please note: The warranty does not cover normal wear and tear, or damage caused by improper installation or misuse. If shocks are installed at an improper angle, it may increase bushing wear rate.
