ADS 2.125" and 2.5" Air Shocks feature extra large diameter shock shafts, and heavy duty internal seals to provide maximum support, durability, and performance. A unique feature to ADS 2.5" air shocks is the OD top caps that threads outside of the shock bodies to reduce their overall length by 1" that may allow you to run a longer air shock compared to other brands. All shocks include gloss black anodized components, zinc plated steel shock bodies, and a 7075 aluminum billet shock pistons. ADS air shocks are ideal for light weight rock crawlers, sand rails, and buggies.

Shock Tuning Options
As soon as you place your order, one of our experienced shock tuning experts will review your shock specifications and contact you to finalize the details of your order. All ADS shocks are available with standard or custom tuning. For custom tuning, one of our shock tuning experts will work with you one-on-one to ensure your shocks are built perfectly for your application to provide the best balance of performance and ride quality. Standard valving is also available for do-it-yourself clients or those that plan to re-valve the shocks themselves. Our standard valving is calculated to work well for most typical applications that would utilize this size shock.
