Detroit Speed 041740-DRDS Decalink Rear Suspension, 17 Spline

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 Detroit Speed (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.

Details

The DECAlink™ Independent Rear Suspension features no compromises and exclusive Detroit Speed 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 DECAlink™ IRS works with an original 17-spline differential assembly 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 Detroit Speed aluminum uprights and a two-piece cast aluminum/steel cradle assembly which eases differential housing removal. DSE/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.Remote Canister Monotube Double Adjustable Shock This DSE/JRi shock has all of the qualities of the double adjustable shock and incorporates a gas charged bladder to provide high frequency and low speed dampening control.Remote Canister Shock MountsThese billet aluminum black anodized shock mounts are manufactured for securing your remote shock canisters to the vehicle.
