These coil over shock absorbers are CUSTOM BUILT to order and designed for the 246 Dino/ all 308 series/ Mondial /328 applications, which allows us to set specifications on weight, weight distribution and bounce/rebound performance requirements. These coil overs offer a wide variety of damping adjustment and coil-over spring tensions, allowing you to dial in your shock to meet the specific weight characteristics and overall ride/handling needs of your vehicle. According to the manufacturer the goal has been to design and build a shock absorber with true high-performance capabilities that will deliver superior suspension control and excellent ride comfort. I believe that they have not only met these goals but can deliver better quality than any competitor. Stock production shock absorbers are designed to function in production cars, all of which are built exactly alike. Their shock design parameters are carefully engineered for a single application. These shocks meet the special needs of highly specialized vehicles that have a great variety of ride and handling qualities. Travel is one of the most frequent problem areas in specialty cars, which usually sit lower than production vehicles, thus limiting the room available for suspension mounting. Lowered vehicles are prone to bottom out with soft springs and shocks, while stiff springs cause a harsher ride. This adjustable shock minimizes this problem by providing the builder/tuner with a wide choice of heights, spring weights and six positions of valving, from soft for normal loads, to extra firm for maximum load conditions. The shock valving does not support weight; however, the stiffer the setting the slower the suspension moves because of increase damping effect. The way your car rides is a combination of several factors: travel, shock rate and spring rate. Your suspension system must be able to move freely without bind or the car will tend to move with suspension movement. Suspension bind is caused mainly by incorrectly designed suspension systems. Proper shock positioning is crucial.
American made rebuild-able high performance shock absorbers are designed to perform and built to last. Properly installed, they will give your car superior suspension control and excellent ride comfort for many years-they look great, too!
This shock absorber is machined from 6061 T-6 billet aluminum stock, which provides superior heat dissipation, maximum strength and quality appearance. Special features are an easy six-position damping adjustment, an internally vented oil chamber which protects the top seal from excess pressure and stops leakage, nitrogen gas charging for fade-free damping and consistent operation, and hydraulic anti-topping. Internal 3-stage valve control automatically accommodates variations in sudden shock impulses for consistent damping under all road and speed conditions. Bottom threaded nut quickly changes spring preload to adjust ride height. A 9/16-inch piston rod and 1.25-inch diameter sintered metal piston operating in an inner steel cylinder assure rugged, dependable service. Assembly and spring changing are simple; a press is not required.
Numbered Control Knobs Adjust Both Rebound (12 Positions) and Compression (6 Positions)! The shock absorber is machined from 6061-T6 billet aluminum stock, which provides superior heat dissipation, maximum strength and quality appearance.

Internal, three-stage valve control automatically accommodates variations in sudden shock impulses for consistent damping under all speed conditions. The bottom-threaded nut makes for easy changes in spring preload to adjust ride height.

Valving: All shocks are valved for either street (light) or road race (stiff). Typical springs for street set up are 300 lbs front springs & 250 lbs in the rear - 90% of our packages are set up that way. We have a few twin turbo cars running 300 lbs in rear & 300 in front.
Springs are cold wound, chrome silicon wire then powder painted gloss black. Chrome springs are available as an option. All springs are color coded reflecting the amount of weight necessary to compress the spring one inch.
SHOCK ADJUSTMENT This adjustable shock has six valve damping positions, so you may dial in the ride you like. To increase firmness, rotate the adjusting knob (located at the top of the shock absorber) clockwise. When the knob is rotated all the way out (counterclockwise), the shock damping is at its softest setting.
FRONT UPPER INNER A ARM MUST BE MODIFIED LIKE IN PHOTO BELOW FOR FRONT SPRING & SHOCK INSTALLATION
Note, this modification is simple & easy & does not change the structural integrity of the A arm, many hundreds of these assemblies have been sold world wide & installed since the mid 90's.
Call to discuss your spring rates, we also offer set ups that start off one inch lower than the OEM length. We have versions to fit Dino 246/ 308 gt4/ 308/328.
Prices start at $1995.00 for all 4 coil overs with adjusting wrench. We ship world wide.
