The Proma Star AL is designed specifically with Sportsman Class racing in mind, from Brackets and Super Classes to Shootout Street Car Classes. It is simply the best performance adjustable coil over shock available. The Proma Star AL has been proven to deliver unmatched consistency, reaction and durability.

The Proma Star AL utilizes a 5/8” centerless ground, hard chrome piston rod for unparalleled precision. The one piece body is machined from forged aluminum and bright anodized for unmatched structural integrity and show-winning appearance. No. 8 Acme threads offer easier and quicker ride height adjustments. Valving adjustment is made with one knob that controls both rebound (extension) and bump (compression). Unique in the industry, the Proma Star AL valving is designed to compensate for high shaft speeds while allowing for low shaft speed control. This valving design increases mechanical grip at both ends of the track throughout the 12 clicks of setting adjustments.

The Proma Star AL sealing system beats any design used in the industry. Utilizing aerospace materials, the sealing properties are unequalled and seal drag is virtually eliminated.
 

The combination of superior valving design and ease of adjustment makes the Proma Star AL the best externally adjustable shock on the market today.
