Exotek Racing is always making innovative upgrades to the most popular race rigs on the market. Aluminum, Carbon Fiber and Titanium are the choice materials and my Hot Bodies D413 was screaming for some "Exotek Orange"!!! In this video I show the products I picked up directly from Exotek Racing and how they look installed. Visit my Facebook page to keep up to date at what's going on at The RCNetwork as well as getting sneak peek photos as things come in! https://www.facebook.com/pages/The-RCNetwork/473999849329994 Here's the items I picked up: Aluminum Steering Rack: http://www.exotekracing.com/d413-steering-rack-7075/ Heavy duty machined 7075 alloy steering rack for the HPI D413. Designed for use with ball bearings for the smoothest and most precise operation. Includes 4 ball bearings, 2 shims and hardware. Polished and anodized in factory orange. The rack allows you to set the same bump steer and ackerman setting as the stock rack. Originally Posted by T. Deguzman the +/- raises and lowers the rack 0.5mm for bump steer adjustment. if the + is facing up it is higher, with the - facing up the rack sits lower. you can also put shims under the rack if you need more than 0.5mm. Aluminum Clamping Rear Wheel Hexes: http://www.exotekracing.com/d413-12mm-rear-clamping-hex-set-d4/ Precision machined alloy rear clamping 12mm hex set for the HPI D413! Replaces the stock floating pin hex design. Machined and anodized in factory orange and matches the stock geometry. Includes 1.6mm hard steel pins and 2mm screws. Center Diff Aluminum Cap: http://www.exotekracing.com/d413-diff-cap-alloy/ Sleek low profile bulkhead cap for the D413. Includes 4- M3 CSK screws that insures the bulkheads are lined up straight thanks to the countersunk holes in the heavy duty alloy bulkhead cap and the alloy construction offers increased heat dissipation. Uses common hardware so that center gear acces only requires a 2mm wrench to save time. Machined, polished and anodized in factory orange. Center Diff Aluminum Cap and Machined Spur gear: http://www.exotekracing.com/d413-machined-72-spur-gear-and-mounting-plate/ New heavy duty machined spur gear with alloy mounting plate for the HPI D413. The much stronger machined delrin spur gear does not flex like the stock spur gear so will reduce stripped gears. Includes the machined 7075 mounting plate. The 2 piece design makes for easier spur gear changes- you do not have to open the gear diff and remove outdrives with our 2 piece design. The alloy mounting plate also provides cooling of the diff fluid for more consistent diff action. A 72 spur gear is included. We also offer a spare 68 tooth spur gear separately for stock spec class gearing. Includes alloy steel hardware.
