Upgraded Factory Box Options for ISO Shifter Kit

Buy Now with Core Charge

If you can not send your box in to be upgraded it's no problem. We do not always have upgraded factory boxes in stock but if we do they will be available to order. Your order will include a core charge of $100.00 that will be refunded when you send your old box back in, after you swap them out. Core charges will be forfeited after 30 days, please return your old box at you earliest convenience. If we do not have boxes in stock your other options include sending your box in to be upgraded or going with the Billet Box. All three of these options offer the same performance, convenience is the only difference.
