5072-10 5080-10 BUGPACK SUPER DIFFS After years of intensive research, we are now able to offer the FINEST transaxle Super Diffs ever made. Starting with a high quality, nonporous steel alloy casting and then we totally machine it using only the latest CNC state-of-the-art equipment. Added to this is a precision made steel alloy spider gear section and high tensile snap rings or alloy threaded inserts. Use the spider gears of your choice. MADE IN THE U.S.A.!!! Additionally, we use Buttress-style right hand threads for superior surface strength on threaded models. 5080-10 Threaded Super Diff, Swingaxle, w/o Spider Gears 5081-10 Snap Ring Super Diff, Swingaxle, w/o Spider Gears BUGPACK IRS DIFFS These units provide the needed strength to withstand the abuse of high horsepower engines. They eliminate the stock housing flex problem in addition to providing for an extra pair of spider gears. Units also allow infinite ring gear lash adjustment and do not affect steering or steering brake operation. 5072-10 IRS Differential w/o Spider Gears 5084-10 ALUMINUM SPOOL Weighing in at approximately 7 pounds, this billet aluminum spool is ready to bolt-on to any swingaxle drag car with an eight bolt pattern. Made of 7075-T6 aircraft aluminum, this spool will deliver even traction every pass. This is a must to run hard and consistent!! 5084-10 Aluminum Drag Spool, Swingaxle 5073-10 5075-10 BUS DIFFS & SIDE COVERS It s a known fact that the strongest transaxle available for the air-cooled engine starts with either model 002 or 091 bus trannys. Now add to their strength with these precision made components. Designed to withstand high horsepower and off-road abuse and machined to fit. We also offer the ultimate racing diff, with matching chromoly side cover, identical to the ones that can be found on the top running off-road race cars. 5073-10 002 Bus Diff, 10 Tooth 5073-11 002 Bus Diff, 11 Tooth 5074-10 091 Bus Diff 5074-50 091 Bus Chromoly Side Cover (for 5074-10) 5075-10 Race 091 Chromoly Diff w/matching Side Cover 5081-50 SUPERINGS We utilize the latest technology to have these bullet proof snap rings made from billet. Made exclusively for us by the only factory offering the required process, special hardened steel plates are made to specification in Germany then cut into snap rings with computer controlled lasers. These rings are 160% thicker and have a tremendous resistance to dishing. The radial force is also 160% greater than stock. Stock snap rings fail (two just fail in series) because end gear forces cause the weak ring to dish thus moving the ring tips together. These Superings are stiff and require a good snap ring pliers to install. Also, any existing diff will have to have it s snap ring groove machined wider. 5081-50 Supering For Swingaxle Diffs, Pair 80

SUPER AXLES Crafted from aircraft steel, these axles are precision machined, heat treated and then ground smooth. The middle diameter is not tapered like stock axles. Instead, the middle diameter is constant all the way to the spline, thereby permitting the axle to twist under heavy load which helps prevent transaxle breakage. A must for racing or other high performance applications. 5040-10 Super Axles, 61-66 Bug, Short 26-11/16 5040-11 Super Axles, 67 Bug, Medium 27-13/16 5040-12 Super Axles, 68 Bug & all T-3, Long 28-7/16 5040-13 Super Pro Stock Axles, 3 Shorter 23-11/16, Short Spline 5040-11 TORSIONAL AXLES Torsional axles are a must when racing or off-roading an IRS chassis. By allowing the axle to wrap up like a torsion bar, the shock load to the transmission final drive is reduced. Larger serrations allow both hubs to float and find their natural centers.
