Dr. KDSS FAQs
Are Dr. KDSS parts made in the USA?
Dr. KDSS says its products are USA-made, including its billet aluminum KDSS parts.
What warranty comes with Dr. KDSS parts?
Dr. KDSS does not publish a written warranty. It accepts returns of unused, uninstalled items with approval and a 20% restocking fee.
How fast do Dr. KDSS orders ship?
In-stock items ship from NVMOS in 24–48 hours. Items from Dr. KDSS are usually processed within 24–48 business hours, though custom or high-demand parts can take longer.
What does the B.O.T.C.K. fix?
A lifted solid rear axle puts the track bar at a steep angle, so the axle moves side to side as the suspension cycles. The B.O.T.C.K. raises the axle-side pivot to flatten the bar.
Which B.O.T.C.K. size do I need?
Use the Shorty for about a 1.5 to 3 inch bolt-height difference and the Standard for 3 inches or more.
Does the B.O.T.C.K. require welding?
No. It is fully bolt-on and clamps around the factory mount, with no welding or cutting.
