Are you a proud owner of a 1967-1972 Chevrolet or GMC Glamour/Action line pickup truck? If so, you understand the challenges of maintaining these classic vehicles. One of the most common upgrades is converting your truck's manual drum brakes to front disc brakes. This not only enhances the safety of your vehicle but also improves its handling.
However, if you're planning to lower your truck by about three inches, it's important to note that converting to a front disc brake system may cause some compatibility issues with the existing 6 lug to 5 lug conversion you're also considering. Additionally, ensuring you have the right rear axle is essential to ensure proper installation and alignment.
But don't worry, we've got you covered. With a few modifications here and there, your '68 GMC C-15 2wd long bed fleetside can be transformed into a beautiful masterpiece. One of the first things you'll need to do is purchase a rear axle from a later model truck that's compatible with the 5 lug system. While there are several of these available, we recommend removing the brand name since our primary focus is on the conversion process itself.
Next, ensure that the selected rear axle matches the gear ratio of your existing axle. You can do this by checking the tag on the axle or by counting the teeth on the ring and pinion gears. Once you've confirmed compatibility and gear ratio, it's time to install the rear axle.
The next step is converting your front brakes to disc brakes. This involves replacing the existing drum brake components with new disc brake components, including the calipers, rotors, pads, and brake lines. While this may seem like a daunting task, it's a relatively straightforward process that can be accomplished with basic mechanical skills and a bit of patience.
Finally, it's time to lower your truck by three inches. You can achieve this by installing lowering springs or a lowering kit. Additionally, you may need to modify your shock absorbers to accommodate the new ride height.
By completing these upgrades, you'll not only improve the safety and handling of your truck but also take its appearance to the next level. Your '68 GMC C-15 2wd long bed fleetside will be the envy of every pickup truck enthusiast for miles around.
In conclusion, upgrading your classic 1967-1972 Chevrolet or GMC pickup truck requires a bit of technical know-how and mechanical ability. By following these steps, you can safely and efficiently convert your truck to a front disc brake system, lower it by three inches, and convert from 6 lug to 5 lug. With a little time and patience, you can transform your truck into a masterpiece that will turn heads wherever you go.
