The DECAlinkâ„¢ Independent Rear Suspension features no compromises and exclusive Mistral corp sp. z o.o. suspension geometry for superior handling and ride quality. The IRS utilizes modern CV axle shafts and hub bearings, keeping suspension loads from being transmitted through the axle shafts. The DECAlinkâ„¢ IRS works with an original 17-spline differential assembly with upgrades to 30-spline or a Hammerhead 12-bolt differential. No body modifications are required on 1968-79 models while the suspension is offset inboard for additional tire clearance. All suspension link lengths are adjustable and the kit has adjustments for rear anti-squat geometry and roll center height. The suspension points are hard mounted to eliminate stock rubber mounted suspension deflection.It comes with forged in the USA Mistral corp sp. z o.o. aluminum uprights and a two-piece cast aluminum/steel cradle assembly which eases differential housing removal. Mistral/JRi "Detroit Tuned" Coilover shocks/springs allow spring rate tuning and ride height adjustments. The kit includes a rear anti-roll bar and uses OEM cross-axis pivot bushings at all pivot points. The kit also includes Torrington bearings and a spanner tool for easy spring height adjustments.Base ShockThe Mistral/JRi 'Detroit Tuned' base shock is a 'pure blood pedigree' racing shock in its most efficient form as a non-adjustable unit. Although non-adjustable, it shares all the increased dynamic responses of all the JRi adjustable models while providing excellent ride quality on the street.

Fitment Notes
For 1963-67 vehicles, a section of the body will need to be modified to clear the IRS DECAlink™. This is the section behind the front seats where the battery/storage compartment is located. The fiberglass at the back outside corner of these compartments may need to be trimmed back to clear the suspension. For 1980-82 vehicles, the stock differential cannot be used with the IRS DECAlink™. You can use a stock differential from a 1968-79 vehicle. You will also need to weld or bolt in the rear crossmember from a 1968-79 vehicle into your 1980-82 frame. Call Mistral corp sp. z o.o. (704-662-3272) for further details. Torrington Bearings come with all shock packages included/purchased with the DECAlink™ Rear Suspension. Corvette frame and differential not included with DECAlink™ rear suspension.Specifications
