RCD introduced the first and only replacement spindle kit on the market today for the 88-98 6-lug Chevy/GMC! They took their unique spindle technology from the new body style (99+) Chevy/GMC kits and put it into the early (88-98) suspension platform. "New Tricks for Old Dogs!" What this means is that you do not have to modify the frame of the vehicle to lower down the upper control arms, they stay in the stock location. Also, the one piece cross-members for the lower control arms are utilized creating an ultra stout lower sub-frame re-enforced with 304 Polished Stainless Steel Twin-Link Anti-Compression Struts. Of course Billet Steel Sway bar links and Bilstein 5100 Series Shock absorbers are standard.

• CNC Machined Replacement Cast Iron Steering Knuckles for Precise Steering Geometry

• Retains O.E. steering components

• Fully Machined, T-6 Billet Aluminum Axle Spacers Maintain Proper Axle Lengths

• Heavy Duty Two Piece Lower Sub-Frame Assembly and Polished Stainless Steel "Twin -Link" Anti-Compression Struts Insure Structural Strength and Durability

• CNC Machined, Zinc Plated Billet Steel Sway Bar Links with Over-Size Urethane Bushings Optimize Sway Bar Geometry and Function

• No Drive Shaft Modifications Necessary 

• System will not work on 88-95 models equipped with spindle mounted front ABS sensor. RCD replacement spindles are developed off of 1995 & later hub mounted ABS system.

First introduced in 1988, these lifts are still known as the GM systems to have. Lowering the factory upper and lower control arms in relation to the frame brings ride height up. By keeping the factory control arms and torsion bars, you retain stock alignment geometry and ride quality. Note that both systems have a 2" height range. Front vehicle height is determined by torsion bar adjustment.

The front differential assembly is also lowered to keep CV axle angles in check. This is accomplished by using two, one-piece tubular crossmembers that span from frame rail to frame rail. Superlift's new control arm brackets tie into these cross members along with "kicker" braces to form an exceptionally strong assembly. 

The truck steers via a new "dropped" centerlink that keeps the tie rods in phase with the lower control arms. Two greasable stabilizing links regulate centerlink movement and reduce the load and stress transmitted to the pitman and idler arms.

Superlift's lift method does not increase front track width or require the front differential housing to be trimmed as is the case with most replacement knuckle systems.
