1963-72 C10 Leaf Spring 1½" Drop Shackles
Until now, GMC and Chevy Truck owners with rear leaf springs have found it next to impossible to find drop rear shackles for their trucks because of the 2¼-inch spring width. Our 1½-inch Drop Rear Shackles solve this dilemma, and also offer an additional drop to our 4-inch rear leaf springs. Our shackles come with Polygraphite Bushings and a durable Black powder coat finish.
1963-72 C10 Rear Leaf Spring U-Bolt Set
1963-72 C10 4" Drop Rear Leaf Springs
For Classic Truck owners with rear leaf springs, we offer 4-inch Drop Leaf Spring Assemblies to lower your truck, as well. These brand new multi-leaf assemblies are made right here in the U.S.A., and come assembled and ready to install. Combine with our 1½-inch shackles for a 5½-inch rear slam.

1960-72 Rear Trailing Arm Bushings (Poly-Graphite Upgrade)
1965-70 12-Bolt Rear-End 5-Lug Conversion Axles (Pair) Converting your 1963-'69(and narrow 1970) 30 Spline C-10 truck rear end to 5 lugs just got a whole lot easier, thanks to Early Classic's new conversion 5 on 5" bolt pattern axles. These precision machined parts eliminate the need to re-drill your original axle flanges to accept the newer 5-lug wheels.
With Early Classic's One-Piece Side Window Kit, you can eliminate your '67-'72 truck's vent windows and give it a cleaner appearance. This kit includes clear glass and all necessary hardware to complete two doors. The installation of these kits are fairly involved requiring the removal of both doors along with some cutting and drilling. (These items ship UPS Oversize 2 Class, and bill for shipping at 70 lb.)
Got Horsepower? Early Classic's new Trailing Arm Reinforcement Kit is what you need. This kit consists of two pairs of laser cut upper and lower reinforcement plates, polygraphite bushings, all necessary mounting hardware, and new U-bolts, allowing you to upgrade and rebuild at the same time. While installation does require welding, this kit will give you a much stronger rear suspension capable of handling most anything you can throw at it!
